Editors’ note, July 30: On July 27, the Federal Communications Commission issued an update clarifying the ways its national security restrictions on equipment from foreign companies would apply to robots. The FCC confirmed to CNET that it applies not just to humanoid robots but also to household devices such as robot vacuums, robot lawn mowers and pool cleaners. It requires them to obtain FCC authorization to be imported, marketed or sold in the US. However, it won’t affect previously purchased devices. CNET will not change our recommendations at this time until we have more information about conditional approvals. We will revisit our recommendations as more information emerges. YARD AND OUTDOORS DEALS OF THE WEEK Deals are selected by the CNET Group commerce team, and may be unrelated to this article. Robot lawn mowers are still not common in the US. When I’m testing my robot mowers, people often stop to ask me about them. I’ve tested 15 models over the course of two years, but for most people, they’re novelties. They become more interested when I tell them I haven’t manually mowed my 3,000 square-foot lawn in a full year. For me, these machines are worth their weight in gold, which is good, because that’s about how much they cost — but that may also be changing soon. Newer models could bring key features to a more affordable price, a pattern we’ve seen with robot vacuums. I’m also happy to report that GPS is no longer the main game in town and Real Time Kinetic, or RTK, beacons aren’t mandatory. It’s still around, but it’s taking a back seat to vision and lidar sensors, and to be blunt, thank goodness. My biggest headache when testing this crop of mowers was still GPS, but since fewer of them are using GPS nowadays, that concern may be put to rest in the not-too-distant future. The robots are getting smarter and some of them are getting cheaper — that’s a magic combination. Here are the best robot mowers for any budget and lawn size. What’s the best robot lawnmower? Adam Doud/CNET The Ecovacs Goat A3000 Pro takes the crown as our new best overall. At $2,500 at full price and often on sale for less, it’s good value compared to more expensive models without compromising on performance. It has great wire-free lidar navigation, fast mapping, excellent obstacle avoidance and is easy to set up and use. There are also some neat features, like a built-in string trimmer for added functionality. All this earns it our Editors’ Choice. For an even more affordable option, I like the Terramow V1000 at $1,399 it’s affordable and easy to use, earning our Editors’ Choice. The best robot lawnmowers Goat A3000 Pro / Ecovacs Goat A3000 Pro Best Overall Ecovacs Goat A3000 Pro This mower does a thorough job and has an intuitive app. The string trimmer can be a game changer by itself. The mower performed well in all of my testing, including adding new areas to the map and adjusting existing ones. It also did well with obstacle avoidance in my soccer ball test, where I leave a soccer ball lying on my lawn, though it left a healthy portion of lawn around the ball unmowed — it’s conservative with obstacles. For $2,500, it’s an excellent value for what you get and earns our Editors’ Choice award. Now that robot mowers have pretty effectively figured out how to cut grass and keep it short, they can now focus on attacking all the other aspects of lawncare. The Ecovacs GOAT 3000 does that with an on-board string trimmer. Other than that added feature, this one is similar in look to the one I evaluated last year but the string trimmer completes the package. My fence is a typical wood picket-and-post fence, with the posts sticking out about 4 inches into my yard. I did not map my yard to include those posts. Instead, I just ran the mower in a line down the fence. From there, the lidar can detect where the actual barrier is and get close enough to use the trimmer. The only problem is, that the option is buried in the settings and it took some doing to find it. I can see why this option isn’t on all the time, or at least by default, but discoverability can be an issue for a feature that really should be the key selling point. As for the rest of the functionality, the mower works great. It’s fast, efficient, and quiet. It does a great job mowing the lawn and I had no issues with obstacles or other impediments. It neatly navigated its way around anything that got in the way. Lawns with large holes or difficult-to-navigate tree roots could be a problem. The EcoVacs Goat A3000 got stuck on tree roots in my lawn until I made a no-go zone to avoid them. Fast, efficent and quiet performance Built-in string trimmer Smart lidar implementation and effective navigation Cheap plastic chassis Gets stuck near tree roots Terramow V1000 isn’t the same as Eufy, but it looks similar. / Adam Doud/CNET Best ease of use and tied, best budget Terramow V1000 A great option for those with smaller yards and without notable boundaries in between. It’s a small, compact robot mower priced competitively with other budget models like Sunseeker’s S4. It’s one of those robot mowers that does what you want, when you want it. The Terramow V1000 looks a lot like the Eufy E15, which I tested last year, so I asked Eufy and Terramow why. It turns out it’s because they use the same parts bin. Terramow is the customer-facing side of Muxin, which designed the hardware for both companies. After Muxin delivers the hardware, Eufy (a subdivision of Anker) implements its software layer, and then distributes the mower through its channels. Terramow in the meantime, delivers a similar mower, but without the rest of the Eufy ecosystem/distribution channels. The Terramow V1000 is ridiculously simple to set up and get started. Within 20 minutes, I had the mower set up, on the docking station and almost ready to work. There was one hiccup — it needed a firmware update that took almost 30 minutes to complete right after I opened the box. That part was annoying, but from there it was just a matter of letting the mower map itself and go. It only relies on GPS and vision sensors to determine its position and it works like a charm. The V1000 does a great job cutting and obstacle avoidance is spot on. If and when it gets itself into a pickle, it will automatically recommend adding a no-go zone to the map so it doesn’t happen again. Also, at $1,399, it’s competitively priced to other affordable models like the Sunseeker S4. Beyond that, it’s simple to set up and use. People with larger yards, and those with no boundaries between yards, like sidewalks or fences, may have some trouble. The V1000 is a smaller unit, so it takes longer to mow larger yards and may have more trouble climbing slopes. Easiest set up and use out of every robot mower I tried Self-mapping is simple Highly affordable Not for large lawns Not a great climber The adorable and tiny Sunseeker S4 is a great budget pick. / Adam Doud/CNET Tied, best budget Sunseeker S4 The Sunseeker S4 is a great little mower — emphasis on little — that sets up easily and uses a lidar sensor. Last year’s Sunseeker required an RTK beacon, so I’m glad to see that’s no longer the case. The S4 is primarily for someone with a smaller lawn. Since the mower itself is very small (7-inch cutting width), it’s meant for yards under 0.25 acres. While the retail price is around $ 1,300 to $1,800, the Sunseeker S4 is often found on sale for as little as $1,000, making it a better option than the Terramow V1000 if you can get it at the right price. The Sunseeker S4 is a great little machine that’s easy to set up. The S4 is supposed to be able to automap your yard, like the Terramow, but I could never get it to work. It would move off the charging station and fail right away. However, I was able to manually map my yard by driving it around, and once I did, it worked perfectly. The lidar sensor on the top of the mower is protected by a brush that covers it when the mower is docked. Not only does this keep the sensor from getting dirty, but it also brushes off excess dirt when the mower pulls in and out of the station. It’s a nice extra touch that none of the other lidar-toting mowers had. The mower I received from Sunseeker included red-and-black decals you could stick on it. They were supposed to make the mower look like a ladybug, but I got strong Deadpool vibes off of them. That’s why I named the mower “Wade.” It was a nice little touch that added a bit of personality to the mower and I very much enjoyed it. If it isn’t obvious by now, the S4 is not meant for larger lawns at all. The cutting width is narrow, so larger lawns would take forever, and likely multiple sessions. That’s not ideal. If your lawn is too big, you should spend more money on a mower that can handle the bigger lawns, like the Segway Navimow X430. Smart lidar sensor protection Adorably tiny, doesn’t take up much room at all Inexpensive and often on sale Smallest yard trimming capabilities Never got the self-mapping feature to work right Dreame A3 AWD Pro / Adam Doud/CNET Best design Dreame A3 AWD Pro The Dreame A3 AWD is the company’s first shot at a mower and it’s impressive for a first-generation product. The mower itself is sleek-looking, comes with lidar and, as has been the theme, has no RTK beacon. Notably, it also has dual spinning discs, providing a wide cutting path for quick mowing. The mower has dual spinning discs under its chassis, which makes short work of the lawn with a 15.8-inch cutting width. It works fast. The mower is driven by spiked wheels in the back and all-wheel wheels on the front that spin and rotate around an axis, which are fine, but I’m not a fan of those kinds of wheels — they’re not efficient and don’t do your grass any favors. But you can’t argue with the cutting width. Lidar is also optimal. This mower mapped my lawn quickly and performed very well every time I set it out, with one notable exception, which I’ll outline below. One cool part that no other mower offers is the ability to capture photos that the AI recognizes as obstacles, so you can check them out remotely and decide whether the robot should avoid them. This is from the same company that uses AI and a robotic arm in its vacuum to sort your socks and is working on a stair climbing model, so I like what Dreame has brought to this space. At $3,100 at full price, it’s also one of the more expensive models we recommend and comes in configurations for lawns ranging from 0.62 to 1.2 acres. The most expensive unit will cost you around $3,500. People whose lawns get stuck on the ground — those who have a large tree like me — might find this mower to be a headache. On multiple occasions, the mower stopped working because it picked up a stick off the ground and got it wedged into one of its discs. If you don’t have a tree, you shouldn’t have a problem. The app itself is intuitive, except for one major annoyance — ads. There is a persistent ad for other Dreame products at the top of the app, and every now and then, you’re asked to subscribe to get updates and promotions. No, thank you. Beautiful machine and design Wide cutting path and fast cutting Smart AI functions Prone to disc jams Multidirectional wheel design may damage grass Persistent ads in the app Segway Navimow X430 / Adam Doud/CNET Best for big lawns Segway Navimow X430 The Segway X4 performed admirably at mowing a larger yard, up to 1 acre. My yard itself isn’t particularly large, but when you add my elderly neighbor’s front lawn, it becomes significantly larger. That’s where the X4 excelled. The Segway X4 primarily relies on a GPS signal, but it uses Network RTK to find its position. That still relies on an initial GPS signal to get things going, but once acquired, there are no issues. The Mower can pilot itself around obstacles and in and out of tight spaces. The app is also intuitive. It can even use its vision sensors to map your yard — assuming you have barriers, like sidewalks and fences. Otherwise, you can pilot the mower around your yard’s periphery. The mower moves quickly and efficiently, often covering almost 4,000 square feet of my and my neighbor’s lawn and rarely dipping below 50% of a charge on any occasion it went out. Plus, the mower is among the best at getting itself unstuck. That doesn’t sound like a big deal, until you’re mowing your 2-acre property and you don’t have to go rescue it. I particularly like the mower’s front wheels, which turn 180 degrees individually to give it a zero-turning radius, which helps it maneuver — to a point. But this is a big machine that can mow quite a bit before the battery gives up. Plus, it can handle getting nearly run over by an SUV, and that’s based on a true story. Overall, this is a reliable machine that can cover a lot of territory for you, and at $2,500, it’s reasonably priced for something that can tackle lawns up to 1 acre. This is a great mower with two flaws. The first is its ability to maneuver in a tight space. The area where I kept this mower is the same place I kept its predecessor last year. Despite its rotating wheels giving it a tight turning radius, leaving and returning to the charging station posed challenges. So if you plan to keep this mower in an open area, you’ll be fine. If it’s a tight space, you may want to reconsider. Excellent battery life Can cover lawns up to one acre Very wide cutting path Tough design Relies heavily on GPS signal which can face interference Can struggle to manuevur in tight spaces The tank-like Lymow One Plus. / Adam Doud/CNET Best all-terrain and toughest build Lymow One Plus Put simply, nothing stops the Lymow One Plus. I stuck this mower into my dramatically overgrown garden, featuring weeds over 4 feet tall and 0.75 inches thick. This mower ate them for breakfast. This is a tough little machine. The Lymow One Plus is the only mower I tested this year with two unique features not offered by any other mower: First, it has treads. That allows the Lymow One Plus to crawl over just about any terrain, including the legs of my trampoline. The second feature the One Plus has is rigid metal blades. Every other mower I’ve tested thus far has had spinning discs with razor-sharp blades attached. Both of these attributes make the Lymow One Plus ideal for thicker vegetation — for example, if you have thicker brush on the edges of your lawn, this mower is for you. The app is user-friendly; it even gives you real-time GPS signal information, which is nice, but it has some downsides I discuss below. Adding zones and setting schedules are easy and the mower does a complete job. It’s not as tough as last year’s Yarbo Core — I towed my car with that machine once — but it’s a nice, happy medium between that and the other mowers I tested. The price is not too high either, but it is in the highest bracket of the mowers I tested. Bear in mind this mower does not have lidar, using GPS and RTK for navigation instead. This mower is heavy and solid and well-built and the rigid blades mean you won’t have to change them frequently — if at all. This mower has an RTK beacon and naturally, this was the one mower I had technical problems with. My backyard is where GPS signals go to die, so this mower gave me the most trouble setting up. If you are not using this mower in a wide open field with clear views of the sky, skip it. Yes, it’s a tough little machine, but if you can’t get a GPS signal for it, all you can do is drive it around like the RC lawn mower from Honey, I Shrunk the Kids, which is still fun, but also defeats the purpose. Finally, at $3,200 for its larger 10-amp battery model, it’s one of the pricier options next to the Segway Navimow X430. If you need its rugged capabilities, it’ll probably be worth it; if you don’t, you’ll be overspending. Tank treads can climb over any obstacle Powers through tough vegetation Can handle large lawns up to 1.73 acres Fun to drive on remote control Loudest mower I’ve tested Relies on GPS and RTK beacons Recent updates Adam Doud/CNET June 2025: This best list is brand new with the Segway Navimow, Eufy E15, Sunseeker X3 Plus and the Husqvarna 410 iQ, tested through May and June 2025. September 2025: Added a new section covering robot lawn mower industry developments in 2025. October 2025: Added the robot lawn mowers I’m currently testing. April 2026: Tested three new models and added the Ecovacs Goat A3000 as a new recommended pick. September 2026: A complete overhaul with six new robot mowers tested. What’s new in robot mowers in 2026? Mammotion says the Luba 3 AWD Series can handle inclines up 38.6 degrees. Ajay Kumar/CNET Lidar is in One delightful surprise about this year’s batch of robot lawnmowers is the fact that they’re all working! I know, that doesn’t seem like a high bar, but here we are. In reality, some of the mowers I tested last year never actually mowed my lawn, and the main problem — by a long way — was GPS. In order to use GPS successfully, you need to have a clear view of the sky, and be clear of obstructions. That’s why every robot lawnmower manual you used to receive told you to place the robot more than 7 feet away from buildings and not under trees. Further, most of the robot mowers I tested had an RTK beacon that required its own set of wires, and building clearance. Adam Doud/CNET This year, most of the mowers I tested didn’t even have an RTK beacon. Instead, lidar was the star of the show. Companies are now able to use weak GPS signals, along with visual and lidar data to determine positioning, which makes the mowers much easier to set up. But, lidar also makes mowers more expensive, so it’s a big trade-off. Fortunately, I got every mower sent to me up and running. There are still some rough edges to figure out, but 2026 was a big and positive step forward in robot lawn mowing. RTK beacons are (almost) a thing of the past Adam Doud/CNET One interesting innovation that’s come to consumer mowers in the last year is networked RTK beacons. Like an RTK beacon, network RTK uses a series of fixed points on Earth, such as cell towers, to find its place on the planet and communicate its position to GPS satellites. This allows consumer mowers to use RTK without requiring the extra RTK hardware. One of the mowers I tested (the Lymow One Plus) still ships with an RTK beacon and that’s the one I had the most trouble with. The Segway mower is the only one that uses network RTK, and it experienced some trouble with connectivity throughout the testing period, but it managed to mow the lawn most of the time it was scheduled — in fewer than 10% of the scheduled mows, the GPS couldn’t get a good enough signal to begin mowing, but that was the exception, not the rule. The future of mowing seems to be lidar and vision sensors. These mowers still rely on GPS, but they store a database of visual data. The GPS gets the location close, and the vision data pinpoints the location. IFA Berlin showed wire-free navigation and all-wheel drive are here to stay The S2 Max comes with a trimming arm to clean up tight edges.CNET Robot mowers were all over IFA Berlin this year and all of them had wire-free navigation. They could also handle steeper slopes and inclines with all-wheel drive. Roborock’s RockNeo Q2 Lidar, as the name suggests, uses lidar to navigate complex yards. It can handle slopes of 45% and passages as narrow as 60 centimeters. Eufy similarly showcased the S2 Max, the first Anker robot mower developed entirely in-house. It uses vision-based SLAM navigation and real-time 3D mapping. It has all-wheel drive and can handle terrain up to 80% slopes and has an extendable trimming arm. Many robot mowers give you a first person view of your lawn while mowing.Adam Doud/CNET Mammation also showcased its new Luba 4 AWD, which similarly uses a 360-degree lidar and a four-camera array for its vision system and spatial awareness. It also has bidirectional driving with independent front-wheel steering and tight trimming against fences and lawn borders. The company also showcased the heavy-duty Maston commercial robot mower, designed for large landscapes, turf maintenance and other heavy landscaping needs. Finally, Yarbo unveiled its M series, a compact mower with the company’s classic tracked chassis. It can handle a variety of mixed surfaces, grades of 35 degrees and edges of around 2 inches. It also uses network RTK and optional lidar, so there are no boundary wires. Robot lawn mowers compared Other robot lawn mowers we’ve tested Adam Doud/CNET The following robot lawn mowers are ones I tested, but which didn’t make the cut (for a variety of reasons), are discontinued or have been recently replaced by newer models. Segway Navimow X390 The Segway Navimow X390 will cost you $4,500 at full price, but it once had the best performance. Adam Doud/CNET The Segway Navimow X390 was our previous best overall and Editors’ Choice pick, but it’s been replaced by newer models, and it doesn’t seem broadly available anymore. If you can still get it, it’s relatively easy to set up and covers a huge area on a single charge. This model is definitely for people with larger lawns. Using a mower like this in an urban setting might be overkill. The mower was also the easiest to set up and use with an RTK beacon, which is a nice bonus. It’s small and fast, with spiked wheels for easy driving. It smartly negotiates difficult terrain, which doesn’t sound like much. But not only does it climb hills well, but when it gets stuck, it uses a variety of techniques to get back underway. You can tell that Segway put a lot of thought into how the mower can free itself. The app is easy to use and set up. Adding to and editing the map is straightforward. The one hiccup I had from a software perspective was getting the mower to mow the area I wanted it to when I accidentally assigned it to the wrong space. Convincing it to do something else was tricky. The Segway’s initial cut left tufts of grass uncut, which was not ideal. A second trip around the lawn largely corrected things, but I was hoping for better results on the first pass. When it was released, the Navimow X390 was fairly expensive at around $4,500, so unless you can find it on a substansial sale, it’s hard to recommend these days. Eufy E15 The Eufy 15 robot lawn mower was the easiest to use. Adam Doud/CNET The Eufy E15 was one of my favorites earlier because it worked without an RTK beacon or satellite coverage, using vision sensors and benefiting from an easy setup. That’s no longer unique, so it drops off our main list, but if you can find it on sale for less than its retail price, it can still provide good value. It’s still easy to love the Eufy E15 mower because, within 20 minutes of taking it out of the box, it was already mapping out my lawn. Less than an hour later, it was mowing, and it finished its first pass almost flawlessly. When it had trouble, the app quickly let me know, and it even suggested setting up no-go zones on the fly wherever it ran into trouble. The cutting was quick and effortless, with good results. Cutting efficiency is excellent — this mower didn’t leave anything untouched. The reason this mower is so simple is that it doesn’t use an RTK beacon to correct its GPS coordinates. The Eufy E15 has a standard GPS receiver (with accuracy down to a few feet) and supplements that with visual data to determine its position. That means two things. First, it cannot run at night because there is no visual data. Second, if there is no physical barrier between your property and your neighbors — a fence, sidewalk and so on — the mower may wander out of its zone If you have a big yard, the Eufy E15 isn’t going to be the best fit. It’s better suited for a small yard like mine (3,000 square feet). It’s also not a good option if being able to set a no-go zone to keep it out of your neighbor’s property, since that’s not something it can do without a physical barrier to contain it. It also won’t work at night since it relies on visual data. Sunseeker X3 Plus The X3 Plus has its drive wheels up front, together with its camera for navigation. Adam Doud/CNET The Sunseeker X3 Plus was another mower I liked due to its adorable design and useful features, but it also falls off our list unless you can get it on sale for less than its $1,600 retail price. I currently see it at $900, which is a much better deal, though there are issues with its sensors and navigation that still hold it back. This model is best for people with medium-sized lawns, and especially those with no barriers at property lines. Beyond that, the mower performs well, and it’s worth noting that robot mowers in general aren’t meant for cutting long grass — they’re meant to maintain short grass. The bump sensor can still be tripped by shorter grass, though. Sure, it’s also tripped by things it shouldn’t mow, like brick borders, but the bump sensor is so low to the ground that it’s maddening. This is even more of a problem during initial setup and even after a few turns around the lawn, so it doesn’t quite make it as our favorite. Husqvarna Automower 410 iQ The Husqvarna Automower 410 iQ has the widest cutting path of the ones we’ve tested at 9.4 inches, but it suffers from poor obstacle avoidance. Adam Doud/CNET Husqvarna has been involved in robot mowers for a long time. It developed the first robot mower in the mid-1990s, which is surprising on several levels. From a sheer looks perspective, the Husqvarna 410 iQ looks like a luxury vehicle in its lines and design. I love the way it looks. It dwarfs most of the other mowers I tested. Unfortunately, its 410 iQ model doesn’t hold up as well these days at its $2,600 retail price, even if you get it on sale. The Husqvarna mower doesn’t have a camera system, relying instead on a radar module on the nose. I didn’t find that radar module to be very helpful, though, since the mower tried to run over my foot twice. I did indeed test this. Not to worry, all my little piggies are still there, but that was a tense moment. The lack of a camera also caused the mower to pop a wheelie on a low brick wall I have around a garden, so it’d be fair to say it didn’t handle obstacles well. If your lawn is curved or has obstacles to avoid, you’ll also want to look elsewhere. Ecovacs Goat A3000 The Goat A3000 is a lidar equipped mower that gives you wire-free navigation. Adam Doud/CNET This Goat A3000 shouldn’t be confused with its Pro sibling, which makes our list. This is a different, earlier model, though there are many similarities, and it was intended for lidar early adopters, which made it more expensive at $3,000 when it launched. The newer Pro model has a built-in string trimmer, while this one doesn’t have it. These days, this is a more common feature, so the main selling point is gone unless you can find it on sale for less. Mowing is fast and efficient, as is charging. Ecovacs advertises that you can charge it to full in under an hour, which seems consistent with my testing. My backyard doesn’t push the mower to its limits, so I never have to wait for a full charge. Speaking of which, Ecovacs also says the mower can cover up to 5,383 square feet in 2 hours, including recharge time. That’s fast for a robot mower. One last little fun point, the Ecovacs Goat A3000 has point-of-view mowing and control. If you want, you can view the mower’s front camera to track its progress. You can also use the remote in the app to navigate the mower and look around if you want. I’m not 100% convinced this is a feature as much as a party trick, but it’s still fun if you have some time to kill and want to clean up a few spots yourself. Hookii Neomow X The Hookii mower is one of the more unique looking ones I’ve tested. Adam Doud/CNET The Hookii Neomow X i starts with the glowing “Hookii” branding across the mower’s front. It glows red, green or blue, depending on what’s happening as it works. There’s a lidar sensor on the top of the machine for guidance and obstacle avoidance. As expected, that means it does not rely on RTK beacons or GPS for navigation. It relies on its lidar and optical sensors to determine its positioning, so I was optimistic about the mower until I ran into trouble. The mower tends to get stuck in a particular area of my yard where troublesome tree roots are growing. So I should have simply created a no-go zone and called it a day. However, every time it got stuck in that area, I absolutely could not get the mower to do anything after that. I couldn’t get it to resume mowing after I moved it. All three of the new robot mowers I tested: the Mammation Yuka, Goat A3000 and Neomow X. Adam Doud/CNET I couldn’t even get it to go back to its charging station. I followed the instructions in the app, which told me to press Resume, then Go, or press Home and then Go, but it just stayed on its error code. I tried pressing the buttons separately and together, but nothing worked. Every time, I ended up having to pick up the 30-pound mower and carry it back to the charging station. Now, if you never have trouble with the mower in your yard, or if you properly set boundaries for exclusionary zones, you likely won’t have this trouble. But in my world, how a device behaves after a failure is almost as important as how it behaves when everything is fine, because in my experience with tech, everything is rarely fine. At $2,300, it’s competitively priced with other wire-free mowers I’ve tested, but its performance didn’t live up to my expectations. Mammation Yuka mini 2 The Mammation Yuka can sweep up leaves in addition to mowing. Adam Doud/CNET The Mammation Yuka mini 2 is another mower I was excited to test out. Mammation’s big feature is that it doesn’t just mow the lawn; you can also get an optional kit that lets it patrol your yard and sweep up leaves. That’s not bad value for a robot mower that only costs $1,560. Plus, it will empty its leaf bin in a designated place, making leaf raking simple. The Yuka also has vision sensors that it can fall back on to help navigate if both the GPS and the RTK beacon fail. At least, that’s what it says it can do. Because my backyard is a Bermuda Triangle of GPS signal that’s led more than one robot mower to failure, the Mammotion Yuka never got enough of a signal to even map my yard, let alone mow the grass or rake leaves. I had hoped that trying the mower later in the season, when the leaves had started to fall, might allow the Yuka to get up and running, but ultimately, that wasn’t the case. Yarbo Lawn Mower Adam Doud/CNET The Yarbo robot mower is an absolute clinic in overengineering. Every other mower on this list arrived at my house in a box that weighed between 40 and 60 pounds. Yarbo’s mower arrived in six separate boxes, two of which weighed over 100 pounds each. There’s a reason for all of this, and it comes back to Yarbo’s mission. Yarbo built a modular system that has a core component and add-on modules for different functions. One is a snow blower, one is a leaf blower and the one I received is a lawnmower. The “core” module, which is what drives the other components, has rubberized tank treads lights around the perimeter, and by itself weighs around over 100 pounds. The mower module weighs another 50 to 60 pounds. If you want to push around snow, you need a heavy-duty build — I totally get that. But at the end of the day, according to Eric Dowd, Golf and Mobile Solutions Expert at Automated Outdoor Solutions, the Yarbo mower is a commercial unit. It’s not really intended for residential use. Adam Doud/CNET The reason I have it listed in this section is that I had an enormous amount of trouble getting a connection to satellites (this was something of a theme). First, I had trouble with the RTK beacon, but once that got resolved, the mower itself had trouble. I have a large tree in my backyard. I’m fairly sure I’m not the only person with a large tree in the backyard, so this is not ideal. I plan to continue testing the Yarbo Core model and its attachments long term. Airseekers Tron Adam Doud/CNET The most oddly-named and oddly designed mower on this list, the Airseekers Tron will run you $2,000. Most of the mowers on this list have two drive wheels and two omnidirectional wheels, like what you’d find on an office chair. The Airseekers Tron on the other hand has two drive wheels and two powered wheels in the front as well. But the wheels in front are canted inward. Rollers on the wheels allow the Tron to be — in theory — more maneuverable. This all looks good on paper. However, there were some issues. First, the Airseekers Tron shipped with comically short cables for both the RTK beacon and the base station. By the time I assembled the beacon and ran the cable through the pipe that holds it up, there was about 4 feet of cable left. If you’re attaching the cable to the base station (more on that in a moment) that means the mower and the beacon need to be in the same space. That may be OK, depending on your space, but really it’s not OK. Adam Doud/CNET To mitigate this, you can plug in the beacon separately, but that requires a separate cord and plug. Airseekers shipped me the unit with European plugs and an adapter for American plugs — a not-waterproof adapter, besides. Airseekers assured me that when the device ships internationally, there will be appropriate plugs on all the cables for each region. Mine is an early unit. When it comes to driving the mower — to map a space. for example — I ran into trouble. The mower would veer off in odd directions. It seemed like the front wheels weren’t functioning as designed. I’ve been working closely with Airseekers support, and the company has been responsive to the issues I ran into, but as of the time this article was published, the mower hasn’t completed the one job it was supposed to do. Factors to consider when buying a robot lawn mower The main thing to remember when buying a robot lawn mower is that your lawn care days are not done. Eric Dowd from Automated Outdoor Solutions pointed out that most of the company’s residential customers still had a bunch of work to do, even after the mower was done doing its thing. Grass trimming along the edges is a big one — in Chicago we call it “weed whacking.” As with a traditional mower, there’s always some grass left over that the blades can’t reach because of the chassis. You’ll still need to do that with a weed whacker (sometimes referred to as a weed eater or string trimmer). Plus, as mentioned, if you have any narrow grassy paths, you’ll likely have to cut them manually with the same trimmer or a traditional lawn mower. However, some newer robot mowers now come with built-in string trimmers to help you with this task too and they’re getting increasingly better at navigating narrow walkways. Adam Doud/CNET Here are some other things to keep in mind when picking the best robot lawn mower to buy: Yard size compatibility (square footage ranges): Consider whether the mower is designed for larger or smaller lawns. A small yard is typically under 5,000 square feet, which is the case for me. A medium yard is usually between 5,000 and 10,000 square feet. Finally, large yards are 10,000 square feet or more, though this will vary according to urban or suburban areas. Some robot mowers are best for urban settings or medium-sized yards, while others are suited for large areas. Your mower should be able to efficiently and effectively cover your entire lawn without running out of battery or taking an excessive amount of time. Navigation technology (boundary wires, GPS, vision systems): Determine what navigation system the mower uses. Options include GPS with RTK beacons for precise location accuracy, vision sensors that use cameras to map and navigate, or boundary wires that define the mowing area. GPS coverage can also be a factor, especially in urban settings with potential signal obstructions. Cutting performance on different grass types: Understand if the mower can handle different grass types and conditions. Thicker grass or variations in grass length can affect mower performance. Some mowers may struggle with dense or tall grass, while others are designed for more challenging lawns. Cutting width: This refers to the width of the area the mower cuts in a single pass. A slimmer cutting radius might mean the mower needs to make more passes to cover the same area. Slope handling capabilities (maximum degree): Evaluate if the mower can climb hills and handle uneven terrain. Some mowers are better at navigating difficult terrain than others, with varying degrees of slope they can manage. Ensure the mower can handle any slopes or inclines in your yard. Battery life and charging time: Consider how long the mower can run on a single charge and how long it takes to recharge. This affects how efficiently the mower can cover your lawn and how long it will take to complete a mowing cycle. All the robot mowers we tested came with docking stations. Weather resistance (rain sensing, IP rating): Determine if the mower can operate in different weather conditions, including rain. Some mowers may have features to delay mowing if it’s raining, while others are designed to be fully waterproof. Check the IP rating for water resistance level. Obstacle detection and avoidance: Evaluate how the mower avoids obstacles, such as trees, garden beds and other objects in the yard. Options include vision sensors that identify objects, radar modules that detect obstacles or bump sensors that trigger a change in direction upon contact. Noise level (decibels): Consider the mower’s noise level, especially if you have close neighbors or prefer a quiet environment. Different models produce varying levels of noise, so check the decibel rating. Smart features and app control: Almost all robot lawn mowers have smart features and app control for scheduling, mapping and other functions. This can include remote control, scheduling mowing times, creating virtual boundaries and receiving notifications. How robot lawn mowers work Robot lawn mowers of yore started off using a boundary wire to determine where they could and could not go, and they were problematic. The boundary wire had to make a complete, unbroken circle. And if anything happened to the wire, you had problems. These days, robot mowers work via GPS, but it’s GPS with a little bit extra in an RTK beacon. Scott Porteous, head of robotics for Husqvarna broke it down for me. Adam Doud/CNET GPS navigation GPS today is accurate down to a few feet. That’s fine when you’re navigating in your car, or looking for Tupperware in the woods, but it’s not good for things like property lines. The RTK beacon also communicates with GPS satellites to provide a fixed location on Earth that the satellites know about. In essence, the RTK beacon tells the satellites, “I’m always here.” Meanwhile, the mower drives around, and the beacon tells the mower that the satellites think it’s 5 feet to the north, so the mower should take the location that GPS is reading and adjust it accordingly. This allows robot mowers to get accuracy down to the centimeter. GPS coverage Another thing to consider is your general GPS coverage. If you live out in the suburbs, there’s a good chance you’ll be able to find a spot in your yard to set up a base station and RTK beacon. If you live in the city, that might be challenging. Also, wherever you set up your mower, you’ll probably need to be within Wi-Fi range for the mower to operate properly. Adam Doud/CNET Cutting width Robot mowers have a lot of difficulty with narrow paths. The reason for this is due to those blades and its overall construction. For example, the Segway mower’s chassis is 20.5 inches with a cutting width of 9 inches. The Sunseeker, one of the smaller bots, has a 14-inch width accompanied by a cutting width of 8 inches. This is not conducive to cutting narrow paths. Even if the body of the mower fits there, it can’t get the right angle to cut all the grass. Mostly, they just wiggle back and forth, which doesn’t do a heck of a lot. Camera systems Most mowers have camera systems that allow them to avoid obstacles and navigate. Eufy relies on that camera system, so much so that it can’t operate at night at all. Other mowers have the ability to turn off nighttime mowing because obstacle detection is a lot worse for obvious reasons. Adam Doud/CNET Scheduling All of the mowers have scheduling abilities, so the mower only runs when you want it to. Some of the mowers even take weather into account — if it’s raining when it’s time to mow, it delays the mowing. It’s important to remember that consistent mowing times are crucial to the proper operation of the mowers so the grass won’t get too long for it to handle. Human oversight Finally, it’s important to remember that robot mowers are exactly that — robots. A human can look at a patch of grass and know exactly how to move through it. Robots, not so much. It can be frustrating to watch a mower make its way through a lawn and just skip past a piece of grass. If you don’t obsessively watch the mower (like I had to in order to review them), you might come back after it runs a cycle and see patches that it skipped, which can also be frustrating. As a human, you might have to do some tidying up after a robot mower, but it’ll be significantly less work than doing the whole thing yourself. Adam Doud/CNET My backyard is a wonderful minefield of obstacles and grades that embodies just about any condition you might have in a yard. I have a trampoline that none of the mowers seemed to be able to navigate (they can’t climb over the supporting pipes on the ground). My tree is large and has roots sticking out of the ground. I have dogs who were curious about their new robot friends creeping back and forth across the lawn. I also have a fair amount of landscaping and some narrow paths that none of the mowers did a good job of cutting. My front yard is much more straightforward, except neither of my neighbors have a boundary between their property line and mine, so I had to rely on GPS and the RTK beacon to test. I found them to be accurate enough. Adam Doud/CNET During my testing time, temperatures varied wildly from 40 degrees Fahrenheit to over 90 degrees — welcome to the Midwest. We also had a few rainstorms, including one torrential downpour that didn’t kill any of the bots, so that’s a plus. After every mower did its thing, I waited several days for the grass to grow back to test the next one, however I didn’t wait too long because — again — maintenance, not mowing. I put these mowers through their paces for the past six weeks, but I anticipate some long-term testing will be necessary. We plan to keep this list updated with more mowers as they’re released, or even mowers we didn’t get to this time around, so be sure to check back. Robot lawn mowers vs. traditional mowers The most obvious difference between a robot mower and traditional mowers is in the fact that robot mowers mow by themselves. This is going to be a long-term investment in getting your time back. Plus, as I told my wife, “Sure the robot mower takes longer than our 18-year-old son to mow the lawn, but you only have to ask it once to do it.” Beyond that, a robot mower starts itself, mows by itself, parks itself and charges itself. It’s a true “set it and forget it” tool. The cost savings in frustration alone is almost worth it. Adam Doud/CNET Speaking of which, there’s a huge cost difference between a traditional mower and a robot mower. A traditional push mower will cost a few hundred dollars. Our cheapest robot mower is usually around $1,000 if you can get it on a good sale. The other consideration is that a robot mower isn’t designed to mow a lawn, per se; it’s designed to maintain a lawn. All of the robot mowers I tested recommended that you cut your lawn first before implementing the robot. Once you do, the robot can mow two or three times a week and keep your lawn where you want it. FAQs How hard is it to set up a robot mower? Robot lawnmowers aren’t hard to set up, but they may require tools and some advanced planning on your part. If you go wire-free, the setup is usually a lot easier than running wires with RTK beacons (which require a clear view of the sky), but you’ll want to let the mower do the mapping and updates necessary. You’ll also want to look at our lawn and set up any boundaries and no-go zones for areas you don’t want it to go. Aside from that, setting up a robot mower isn’t much more difficult than setting up a robot vacuum these days. What ongoing maintenance do robot lawn mowers require? Robot lawnmowers are largely self-sufficient devices that run when you tell them to, charge themselves and don’t require supervision most of the time. Some newer models I saw at IFA even self-clean and rinse their blades when they dock or automatically seek shelter during inclement weather. Maintenance comes in the winter when you need to store them. It’s a good idea to replace the blade, too. Beyond that, they’re pretty easy. How do robot lawn mowers handle obstacles and boundaries? Boundaries and obstacles are handled through a combination of GPS, visual sensors, radar, lidar and app controls. Once you set the boundaries, you can also set “no-go zones” that the mower will avoid. Other obstacles are detected by onboard sensors, which generally keep the mower out of trouble. As with all things tech, this has been steadily improving over the years and the newer robot mowers are quite good at avoiding obstacles, though sometimes they can be too cautious.
