Top 3 Robotic Lawn Mowers (2026), Tested and Reviewed

Perhaps unexpectedly, the setup instructions for your robotic lawn mower will likely tell you to start by cutting the grass. Robotic mowers often cannot handle tall grass. Unlike traditional mowers, these robots do not collect grass clippings; They mulch instead and are designed to be cut frequently, keeping your lawn short and leaving clippings on the ground, which can also improve the health of your lawn. Most robotic mowers are designed to run two or three times a week during the growing season (late spring to early fall).

It has rechargeable batteries and can last from half an hour to several hours on a full charge. They return to the charging base and are automatically recharged when they run low on power. Most mowers have simple controls, a small display screen, and an emergency stop button. You can generally start and stop mowing, set schedules, and create or edit designated zones using the on-board controls or the accompanying mobile app, just like a robot vacuum.

There are many robotic mower features to consider, and the best option for you will depend on the shape of your lawn.

Grass size and shape

Robotic lawn mowers are generally rated to cover a specific square foot area, with wider coverage requiring models with larger batteries. Besides the size of your yard, you should consider the shape and terrain of your garden, as most robotic lawnmowers will have difficulty on steep slopes. Although you can often draw separate zones so your robot mower can mow the front and back lawn, for example, it will generally need to be lifted and carried between those zones. If you have an uneven lawn or steep slopes, you should look for a four-wheel drive (4WD) mower or all-wheel drive (AWD) mower and check the manufacturer’s slope rating.

Navigation type

There are a few types of navigation used by robotic mowers. We tested five different methods, although some mowers combine multiple technologies for better performance:

• Satellite: These mowers often use what is called Real Time Kinematic (RTK) GPS, need a satellite signal to navigate and will have a receiver that must be placed in an open space with a clear line of sight to the sky. Satellite mowers are not suitable for areas with tall trees or buildings.
• Light Detection and Ranging (LiDAR): This technology sends rapid laser pulses to map a 3D terrain (also used in self-driving cars). It enables mowers to cut grass under thick tree canopies or near tall buildings where GPS signals typically fail.
• Cameras: Onboard cameras and artificial intelligence are used to detect and avoid obstacles. AI vision can map areas and automatically cut grass while avoiding obstacles it encounters, just like how most robot vacuums navigate the home to clean floors.
• Wire boundaries: These mowers require you to install perimeter wire as a boundary around your lawn that defines boundaries that the mower must not cross. It’s a messy task that can be difficult.
• Remote control: You can mow your lawn from the comfort of your home using a remote control or an app on your phone. Some operate only via remote control, while others can also cut automatically.

Power and charging

Robotic mowers generally come with large charging docks, and you’ll need to make room for yourself. They usually have weatherproof cables, but you’ll have to find a way to an external socket.

Wi-Fi and Bluetooth

To connect to your mower and schedule a mowing, update the firmware or control it remotely where supported, you need a suitable Wi-Fi signal or Bluetooth connection. It’s best to set up your mower’s charging station within range of your Wi-Fi network. Some mowers also need a strong Wi-Fi signal to operate effectively, so you might consider adding an external mesh router. If you want to connect your phone via Bluetooth, you’ll have to get quite close.

Most robotic mowers are much quieter than their conventional counterparts, and you can expect them to operate at around 55 decibels, although they can be as high as 75 decibels. We’ve only tested battery-powered mowers, but we expect gas mowers to be louder. Although the operation is often quiet, I found that many mowers made annoying beeping noises when backing up or had a loud registering sound during setup or when receiving a command.

Robotic mowers and their charging stations usually have an IP rating and can handle the rain, but you should pack up and bring your mower inside during the winter months. Many robotic mowers have some type of rain sensor and will temporarily stop mowing when it gets too wet. Some mowers may need to be manually paused. Wheels can move your lawn and get muddy if your mowers keep running in the rain, especially with larger, heavier models.

Mowers of different sizes will have different cutting widths, which indicates the width of strip they can cut in each pass. Most also have floating cutting surfaces that let you choose the length of grass you want (usually 1 to 3 inches). Many robotic lawn mowers seem to have trouble cutting around the edges of the lawn, especially if there’s a wall or fence preventing it from getting close enough.

It’s common to find an uncut edge around the edge of your lawn, so you may need to get out your string trimmer every once in a while. Every robotic mower I tested also had difficulties cutting the area around the charging station, so I recommend placing the unit on a deck or paving if possible.

Yes, anyone can install most robotic mowers, but you may want to set aside an afternoon to work out any snags. Finding the best receiver location for your satellite mower can be difficult. The mapping process can also take some time; Your mower’s remote control will usually prompt you about the limits you want to set. After the first cut, you should review its performance and make adjustments to ensure that it covers the entire area you want to cut.

I test each robot lawn mower for at least a month, in at least two different lawn areas, evaluating ease of setup, mapping process, automatic scheduling (where available), navigation, obstacle avoidance, quality of the final cut, looking for length and uniformity and any missing corrections. Where possible, I try additional features, adjust settings in the app, and check how the mower handles different weather conditions. I also monitor battery performance and charging time to ensure it matches the manufacturer’s claims.
