Whether you want to carve out more free time or reduce your carbon footprint, a robot lawn mower could be the answer. But do robots cut as well as a person pushing a mower? Equipped with cutting-edge navigation and obstacle avoidance technology to go along with advanced app-based controls, these autonomous devices leave lawns with the appearance of a perpetually fresh cut. They are easy to use and very reliable, but the technology has rapidly evolved since 2022, when BobVila.com started testing robotic lawn mowers. The latest models no longer require installing labor-intensive boundary wires. They run longer per charge, offer more customization options, and cut better than ever. 

Our current favorite is the Segway Navimow. It cuts the most complex lawns guided by a vision-enhanced satellite navigation system. But it is a bit more expensive than some other options, and has a maximum area limit of a quarter acre. For smaller budgets or larger yards, we have other great options to choose from. In the reviews ahead we discuss how each selected robotic mower performed on our test turf. Afterwards, keep reading to learn about the criteria we used to select the best robot lawn mowers and find one that’s right for your lawn care routine.

What We Like

  • Precise EFLS satellite navigation system 
  • Onboard AI-enabled camera obstacle detection
  • App mapping, scheduling, and mowing on demand
  • Multizone and corridor programming options

What We Don’t Like

  • RTK reference station requires unobstructed sky view

Specs 

  • Coverage area: 0.25 acre (up to 10,890 square feet)
  • Mowing height range: 2 inches to 3.6 inches
  • Slope rating: 17 degrees

Our Ratings: Ease of Use 5/5; Cut Quality 4.5/5; Performance 5/5; Durability 5/5; Value 4.5/5

For ease of setup and reliable navigation, a robot lawn mower with GPS can’t be beaten. Instead of a low-voltage boundary wire, Segway Navimow i110N uses an AI-enhanced satellite navigation system with centimeter-level accuracy to keep it in bounds. An onboard camera, also infused with AI technology, assists the satellite navigation system and helps the mower avoid obstacles.

The Navimow i110N can autonomously mow up to a quarter acre of grass, including slopes up to 17 degrees or about 28.5 feet of elevation change per 100 linear feet. The manual cutting height adjustment ranges from 2 inches to 3.6 inches high to accommodate most lawn grasses. It operates at a quiet 58 decibels, so it is safe for mowing any time of day, even in noise-sensitive neighborhoods. 

Setup took about 2 hours, including installation of the charging base and antenna, downloading the app, and mapping the yard. The instructions were easy to follow. To map the yard, we used the mobile app as a remote control to steer the mower around the zone borders and any excluded areas. Driving the mower took quite a bit of trial and error. Scheduling was easy and very flexible. The app allows for multiple zones, travel corridors between zones, and multiple mowing cycles per day.

Navimow may also be an appealing option for those who like lawn striping. Unlike most other mowers in this guide, Navimow mows in parallel lines, producing a pinstriped appearance due to the 7.5-inch width of cut. During each mowing cycle, it cuts along a different axis: first north to south, next northeast to southwest, then east to west, and finally southeast to northwest before repeating. 

The basic Segway Navimow i110N kit includes the mower, charging station, antenna, and power cord. The one we tested came with a few upgrade features, including the Garage S charging base shelter, the Access+ 4G signal backup module, and the antenna extension kit. We consider the Garage S a necessity as it added a layer of protection against sun, rain, dirt, and debris. Since the satellite signal in our yard was really good, we didn’t notice a difference after adding the Access+ and antenna extension. The mower stayed in bounds at all times, mowed on schedule, and had no problem keeping up with our quarter-plus acre of grass.

What our tester says: “The best new robot mowers don’t need guide wires, and that is just the starting point for Segway. It was the fastest and easiest to set up and the first model I’ve tested that was able to cut perfect lawn stripes instead of a random pattern. Segway really did its homework on this one.” —Mark Wolfe, Product Reviews tester and writer

What We Like

  • Height-of-cut range suits most types of grass
  • Good performance on slopes up to 30 percent
  • Intuitive programming via mobile app
  • Program up to 3 different starting points

What We Don’t Like

  • Only 60 minutes of runtime per charge

Specs 

  • Coverage area: 0.4 acre (up to 17,424 square feet)
  • Mowing height range: 2 inches to 3.6 inches
  • Slope rating: 17 degrees

Our Ratings: Ease of Use 4/5; Cut Quality 4/5; Performance 5/5; Durability 5/5; Value 5/5

The Husqvarna Automower 115H mows all kinds of grass up to 0.4 acre. Its durable 18-volt 2-amp-hour lithium-ion battery delivers 60 minutes of runtime per charge and recharges in just an hour. The cutting head manually adjusts from 2 inches to 3.6 inches for either warm-season or cool-season grasses, and it’s rated for slopes up to 17 degrees. Bluetooth connectivity lets users control the 115H via the Automower Connect mobile app. Adjust the mower schedule, start or stop mowing on demand, monitor status, and order replacement blades all in one convenient location. This wireless remote control lawn mower also has theft protection with a personal identification number (PIN) and alarm system.

The Automower 115H impressed us as a great choice for most suburban lawns. It easily navigated our test lawn’s slope and obstacles, reliably mowing on schedule and docking securely. The lawn’s appearance was consistent throughout testing, without any obviously missed spots. Working with the Automower Connect app, it was easy to program the schedule, set up different starting points, and pause and restart a mowing program during an active cycle. The guide wire helped the Automower navigate efficiently through a narrow corridor from one broad space to another. 

It’s worth noting, however, that the lack of GPS technology makes this a “less smart” mower than some other models out there. For instance, the 115H did not seem to adjust its mowing patterns and obstacle avoidance as quickly as its more intelligent competitors did. But this model makes a great choice for larger yards and maintaining taller grass.

  • Perimeter wire-free navigation
  • Mows up to a quarter acre
  • Navigates rough terrain and slopes up to 38 degrees
  • Multizone management for up to 10 zones
  • Mobile app controls mapping, scheduling, and cut height

What We Don’t Like

  • RTK reference point requires unobstructed sky view

Specs 

  • Coverage area: .25 acres (up to 10,890 square feet)
  • Mowing height range: 2.2 inches to 4.0 inches
  • Slope rating: 38 degrees

Our Ratings: Ease of Use 4/5; Cut Quality 5/5; Performance 4.5/5; Durability 4.5/5; Value 4/5

Until now, yards with shallow tree roots, rocks, and steep slopes have made robotic mowing nearly impossible. Mammotion addressed these concerns with Luba 2. A weight-balanced design and all-wheel drive (AWD) allow it to easily conquer rough ground and steep slopes with up to 7.7 feet of elevation change per 10 linear feet. Even better, it uses a 3D vision and RTK fusion mapping system to achieve precise navigation without the hassle of a perimeter wire. 

I tested the Luba 2 1000H, which is built to manage up to a quarter acre with a mowing height range of 2.2 to 4.0 inches. Other models in the Luba 2 series can cover up to 2.5 acres, and mow as low as 1 inch.

Setting up the equipment was easy, but the interface was less user-friendly to start. I downloaded the app, turned on the mower, and connected to Wi-Fi with no problem, but I did encounter glitches when I attempted to map the yard. After some investigation, I discovered that the mower’s firmware needed an update. When the update was complete, mapping and scheduling went flawlessly.

The Luba 2 was the only robotic mower I tested that was equipped with twin-blade assemblies, offering an impressive cutting width of 15.7 inches. The cutting width is wider than the wheels, so it also cuts closer to the edge than other mowers. But the most obvious point of separation between Luba 2 and the other robot mowers was the AWD system. This mower easily climbed the steepest slope in the yard and had no problems navigating the bumpy corridor between two separate mowing zones. None of the other models could do that.

What our tester says: “Mammotion’s cut quality was really good, but I was blown away by its sure-footedness. Unlike others that were able to ‘just make it’ up the slopes in my yard, the Luba 2 traveled as well on the inclines as it did on the flats. No slippage and no lost mowing coverage.” —Mark Wolfe, Product Reviews tester and writer

What We Like

  • Largest coverage of any robot mower we have tested
  • Up to 240 minutes of mowing per charge
  • Wide, 9-inch cutting disc with six blades
  • Fast mowing speed

What We Don’t Like

  • One of the most expensive mowers tested
  • Only moderate slope performance

Specs 

  • Coverage area: 2.5 acres (up to 108,900 square feet)
  • Mowing height range: 2 inches to 4 inches
  • Slope rating: 27 degrees

Our Ratings: Ease of Use 5/5; Cut Quality 4.5/5; Performance 5/5; Durability 5/5; Value 4/5

For those in need of a large lawn robot mower, the Segway Navimow X390 is built to handle up to 2.5 acres of grass. It moves fast, cuts a wide swath, and can mow up to 240 minutes per charge. This boundary wire-free robot mower uses satellite guidance through an RTK reference station, paired with AI-enhanced vision capability, to stay on track and avoid obstacles. 

In our test yard, setup only took about 30 minutes. That included unpacking the kit, downloading the app, assembling the base station, connecting power and WiFi, and mapping the yard. Half of the time was spent mapping, so larger, more complex yards will take longer. Still, it was a far cry from the typical 90-plus minutes it used to take to set up perimeter wires. A cool feature that we did not test was the dual antenna system (we only had one antenna), which supports large, complex landscapes where signal drop could become a problem.

Like most of the other newer robot mowers, the Navimow X3 series is compatible with Amazon Alexa and Google Home. Unlike most of the others, it includes four layers of advanced security features: an out-of-bounds alarm, a lift alarm, GPS tracking via the mobile app, and secret compartments where third party item trackers may be stored onboard. As far as mowing is concerned, it also comes with a “Doodle” feature, a series of preset patterns that it can cut into the grass for a fun, decorative touch.

This machine is fast, averaging 1 meter per second. During the 2-week test period, the Navimow X390 mowed an average of 2,810 square feet per hour. It only took 1.9 hours to mow the same amount of space that required 2.25 hours or longer from the others in the test group, including some with dual cutting discs. The two key points of separation were the X390’s fast pace and big battery. It was one of only three mowers that was able to cut both zones without stopping to recharge. It made perfect parallel stripes, alternating the stripe directions from one cut to the next, and never left an uncut strip.

  • AWD system works almost anywhere
  • “H” model we tested is ideal for tall grass maintenance
  • AI vision-enhanced mapping and obstacle detection
  • Excellent cut quality

What We Don’t Like

  • Vision sensor malfunctions if not kept clean
  • Premium price point

Specs 

  • Coverage area: .38 acre (up to 16,553 square feet)
  • Mowing height range: 2.2 inches to 4.0 inches
  • Slope rating: 38.6 degrees

Our Ratings: Ease of Use 4/5; Cut Quality 5/5; Performance 4.5/5; Durability 4.5/5; Value 4.5/5

For small yards with varying terrain, the Mammotion Luba Mini offers the most effective, carefree robotic mowing in our experience. It does not use a boundary wire and easily climbs slopes up to 38.6 degrees. The model we tested (1500H) covers up to .38 acre per charge, with a height-of-cut ranging from 2.2 inches to 4 inches, making it ideal for taller, cool-season grasses. For the smallest yards, model 800H covers up to .2 acre per charge, and saves a few hundred dollars. The Luba Mini also comes in 1500S and 800S versions with a lower cut height that is better for warm-season grasses.

The Luba Mini mowed our entire test area in about 2.75 hours, including a break to recharge. It cut beautifully without missing a spot. We selected a random cut pattern, which varies the stripe angle each time it mows. We noticed that when two adjacent zones were both mowed randomly, the pattern did not match up. So, visually, it’s best to create map zones with this in mind and create the zone boundaries in inconspicuous areas. The only challenge we encountered was after mowing a large area of slightly overgrown, damp lawn. Some of the grass clippings adhered to the vision sensor, making it difficult for the robot to return to charge. This happened twice during the test. 

As with all satellite-guided mowers, the question of where to place the RTK station is important. It needs full exposure to the sky, but shouldn’t be in the most obvious location to avoid theft. Thankfully, the kit included lots of extra wire and an extra power cord, just in case we wanted to locate it far from the base station. We even had the option to mount it on a wall with the included wall anchors. For our tests, we simply mounted it on a fence post near the charging station.

What We Like

  • Syncs with popular EufyHome app
  • No perimeter wires or RTK antenna needed
  • Several incorporated safety features
  • Onboard camera for real-time view

What We Don’t Like

  • Best for low-growing grass
  • Wi-Fi range limited to about 50 feet

Specs 

  • Coverage area: 0.2 acres (up to 8,712 square feet)
  • Mowing height range: 1 to 3 inches
  • Slope rating: 18 degrees

Our Ratings: Ease of Use 4.5/5; Cut Quality 4/5; Performance 4/5; Durability 4/5; Value 4.25/5

We’re big Eufy fans. So when the Eufy E15 robot lawn mower arrived for testing, we had high expectations. Setup was refreshingly simple—it’s about as close to plug-and-play as robot mowers get. The mower arrived well-packaged, and all we had to do was place the base station in a permanent location and plug it into an outlet. That’s the only wire involved. Unlike many robot mowers, the E15 doesn’t rely on boundary wires or an RTK antenna; instead, it uses advanced visual navigation to define its mowing zone. The E15 allows height adjustment from 1 to 3 inches, but in our testing, it performed best on grass 2.5 inches or shorter—making it a solid match for low-growing grass, such as buffalo. 

Once fully charged (about 1.5 hours), we powered on the mower and the EufyHome app walked us through the setup and let us define the mowing boundaries. Like most robot mowers, the E15 works best on a frequent schedule—mowing daily or every other day keeps the lawn consistently neat and prevents it from getting overwhelmed. It cut well on our buffalo grass, navigating slopes up to 18 degrees and avoiding obstacles with ease. Still, it struggled to cut thicker, taller fescue.

The only real hiccup was with Wi-Fi connectivity—the mower began dropping signal once it ventured about 50 feet from the base. That’s something to keep in mind for large yards or weak Wi-Fi coverage outdoors. However, for those looking for a hands-off way to keep low-growing grass trim and tidy, the E15 delivers. It features a safety shutoff if it’s lifted or tipped, rain detection, and even GPS tracking and app-based locking to help prevent theft.

What our tester says: “I loved how easily the Eufy robot mower synced with my EufyHome app. Now, I can control my Eufy security system and the mower from the same app.” —Glenda Taylor, Product Reviews tester and writer

Testing Stats
Products tested 14
Time spent testing 6 months

Price range$600 to $5,000

When we started testing robot lawn mowers just a few years ago, they all used perimeter guide wires for navigation. Some of our early favorites included Worx Landroid and Husqvarna Automower, and they are still great options for affordable automated lawn mowing. In order to keep up with the latest technology and showcase the best of the best, we test new mowers each year. Now, nearly every new model features perimeter wire-free navigation, powered by either satellite guidance or AI-empowered vision technology. 

To test them, we set up each mower, programmed a weekly schedule, and let it go for two weeks. Our test yards include typical obstacles and mowing challenges like trees, landscape beds, slopes, uneven ground, narrow corridors, and different types of grass. Our “Best Overall” robotic lawn mower has to reliably navigate the lawn while avoiding permanent and temporary obstacles, always stay in-bounds, mow with accuracy and consistency, reliably return to its charging station, and automatically avoid working in poor conditions. We use our observations to rate each mower on ease of use, cut quality, performance, durability, and value. 

What to Consider When Choosing a Robot Lawn Mower

Shopping for a robotic mower is a lot like shopping for a normal one, but there are a few extra things to consider when assessing this new gadget for your home. The following factors should help decide which robotic lawn mower is right for you.

Yard Size

To begin the search for a new self-mowing robot, get an accurate measurement of the area it will mow. Measure the lawn’s square footage, not the size of the lot, and exclude square footage taken up by the house, driveway, landscape beds, and any other feature that is not grass. Often only half of the square footage of a residential lot is lawn space, and sometimes even less. 

Light-duty or portable lawn mowers are best for areas up to a quarter acre, or about 11,000 square feet. Midsize models cut up to a half acre, or about 22,000 square feet. Large machines can cut an acre, or 43,560 square feet, or even more.

Factors that affect how much space a mower can cut include battery runtime per charge, the mower size, and the speed it travels. The “up to X square feet” amount that manufacturers claim is calculated with ideal mowing conditions in mind. Mowing conditions including slopes, obstacles, and irregular lawn shapes, as well as grass type, thickness, and growth rate, may all inhibit a mower’s efficiency and capability. 

Look for a mower that can cut the entire yard on a single battery charge, if possible. For larger yards, it may be necessary to divide the lawn space into two or three smaller mowing zones that the mower can cut on different cycles. Not all robotic mowers have the ability to create and schedule multiple zones, so be sure to buy a mower with that capability if necessary to suit the property size.

Terrain Handling

Basic robot mowers work on flat yards and slopes of up to 15 percent (1.5 feet of rise per 10 feet of linear distance). Yards with garden beds, boulders, pathways, and/or steeper slopes require a more capable model. Look for one with onboard collision-detection systems, GPS, all-wheel drive, and/or multizone programming capability to navigate complex yards.

Mowing Height

Grass type, weather conditions, and terrain influence a lawn’s optimal mowing height. Warm-season grasses like Bermuda, zoysia, and centipede should be mowed to from 1 to 3 inches high, while cool-season grasses such as fescue, bluegrass, and perennial ryegrass should be mowed to between 2.5 and 4 inches. 

That said, allowing grass to grow taller than normal in extreme heat and drought helps protect the roots from dieback. Smooth, flat ground makes it easier to mow lower, while rough terrain requires additional clearance. We recommend buying a robotic mower that allows as much mowing height flexibility as possible within the range for the particular lawn type.

Controls

Robot and remote control lawn mowers are kept in the yard either by a low-voltage electric perimeter boundary wire or more commonly by satellite guidance or AI-supported vision technology. The wire or the smart features help the mower locate the edges of the lawn and steer around permanent obstacles like trees, paved areas, and buildings. An onboard computer tells the mower when to mow and when to recharge. Just program the mowing schedule and set the blade height, and the lawn mower does the rest. Many robotic lawn mowers are Bluetooth capable or Wi-Fi connected, so it’s an option to program them with an app on a smartphone.

Power Source and Battery Life

Robot mowers charge automatically at a home base station. The base station serves as the charging port and the boundary wire hub. The same power source that charges the mower’s battery also sends a low-voltage current through the boundary wire, if installed, to guide the mower. A single power cord plugged into a nearby ground-fault circuit interrupter household outlet provides the needed electricity.

These mowers typically use rechargeable lithium-ion batteries, though some use lead-acid batteries or other types. Depending on the model and mowing conditions, an electric mower can operate between 1 and 2.5 hours per battery charge. Batteries typically need 30 minutes to an hour to recharge. Robot lawn mower batteries tend to last approximately 3 years on average.

Smart Technology

Onboard sensors, Bluetooth connectivity, mobile apps, and compatibility with personal digital assistants all let users program a robotic mower. On its programmed mowing schedule, the mower starts and recharges itself, returning to its docking station when it has finished the job. The mowers’ programming keeps it on the lawn and protects non-grass areas.

Some robotic mowers have a manual mode used to trim enclosed spaces. In manual mode, the robot mower can be moved to a secondary location—inside a fenced area of the yard, for example—and it will mow without further programming. 

Many robot mowers will alert smartphones when there is a problem, if its blades need to be changed, or if the machine is moved off the premises. Mobile apps can also allow the robot mower to be monitored and controlled remotely via a smartphone or digital assistant.

Noise Levels

Robotic mowers are quiet but not silent. They produce an average of 50 to 70 decibels, which is similar to the sound levels of a quiet refrigerator, a calm conversation, or the noise inside a car traveling at 60 miles per hour. A gasoline-powered push mower produces 95 decibels, or about 50 percent more noise than a self-cutting lawn mower.

Security

Robot lawn mowers are small enough that a thief could carry one away. For that reason, many models require a PIN for operation. Others feature alarms, security alerts, and GPS tracking that kicks in if the unit is removed from the owner’s property. Since robot lawn mowers are fairly quiet, people often program them to run at night as a theft deterrent.

Safety Features

Robot lawn mowers have safety features to protect the user and others in their cutting area. The machine moves slowly so pets, children, and others can see it coming and get out of the way. Collision sensors slow or redirect the mower as it nears an obstacle. An automatic shutoff kicks in if the machine is lifted, stopping the blades from moving. And the mower has recessed blades mounted away from the edges of the machine to reduce the chance of cutting hands and feet that come too close.

Weather Protection

Most motorized lawn mowers are built to withstand outdoor conditions during the mowing season. Some robotic mowers can run in the rain, but it is not recommended since wet grass doesn’t cut as smoothly, and wet conditions can spread fungal diseases to the lawn. Some robot lawn mowers have rain sensors that stop, skip, or delay a scheduled mowing in rainy conditions. Other robot mowers can have their cutting schedule manually overridden, so users can turn them off if rain is in the forecast. Still others link to a weather app that will turn the mower off if rain is predicted.

Docking stations are weatherproof during the mowing season. Still, in stormy weather where lightning is predicted, unplugging the system provides the best protection. Extended periods of damp, subfreezing weather shorten the mower’s lifespan, so the mower and its docking station should both be stored indoors in the winter.

FAQs 

An automatic lawn mower can be a great asset for homeowners who want to spend less time mowing their lawn. Still not sure if a robot mower is right for you? Read on for info and tips to facilitate your decision.

Q. How often should I use a robotic lawn mower?

Robotic mowers are designed to cut several times per week. When grass is growing really fast, the robot mower should run every day or every other day. When grass grows more slowly, mowing two or three times per week is sufficient. Follow other best practices for how to mow a lawn.

Q. Can I use a robot lawn mower while it rains?

Some robotic mowers can operate in the rain; others cannot. However, mowing only while the grass is dry results in a cleaner cut and reduced disease spread in the lawn.

Q. How long do robot mowers last?

A properly maintained mower should last 10 years or more. Mower blades last 1 to 2 months. They cannot be easily sharpened; they must be replaced—think of them as disposable razor blades. Rechargeable batteries for robot mowers last about 3 years, on average.

Q. How big of a yard can a robot mow?

Manufacturers will provide an “up to X square feet” amount for a particular model. However, this number is calculated with ideal mowing conditions in mind. Slopes, obstacles, and irregular lawn shapes as well as grass type, thickness, and growth rate may all affect how much a grass cutting robot can handle in one charge.

Q. What are the disadvantages of a robotic mower?

Some models require a perimeter wire, which increases setup and winterizing time. Depending on the mower and the size of the lawn, it can potentially run out of charge in the middle of a job and require recharging before continuing. The device can also leave an unmowed strip around the edge of a lawn that will later need to be trimmed by hand.

Q. Are robotic lawn mowers loud?

Robotic mowers produce an average of 50 to 70 decibels, which is similar to the sound levels of a quiet refrigerator. In comparison, a gasoline-powered push mower produces 95 decibels. 

Q. Does a robot mower mulch leaves?

Yes, an automated lawn mower can chop leaves into smaller pieces that can then be used to mulch a lawn. Some models even have a mulching function. However, although most models can chop up a few incidental leaves, they’re not designed to mulch large quantities.
