A robot lawnmower quietly keeps your grass perfect while you get on with your weekend — no petrol, no pushing, no cuttings to bag. They've gone mainstream and far smarter in 2026, but choosing the right one means matching it to your garden. Here's what to look for.
How robot mowers work
They trim a little grass every day, mulching the tiny clippings back into the lawn to feed it. Older models need a perimeter boundary wire buried around the edge; the newest use wire-free GPS/RTK or LiDAR navigation you set up from an app — no digging required.
What to look for
- Lawn size: match the model's maximum area (600m², 800m², 1,600m²…) to your garden, with a little headroom.
- Navigation: wire-free RTK or LiDAR models are far easier to install and handle complex gardens better than boundary-wire mowers.
- Slopes: check the gradient it can handle if your lawn isn't flat.
- Obstacle avoidance: cameras and sensors stop it bumping toys, pets and flower beds.
- App control and security: scheduling, zones, rain sensors and a PIN or anti-theft alarm are all worth having.
Our picks
- Wire-free and keenly priced: the eufy E15 is a tidy entry into robot mowing.

- Big gardens: the Ecovacs GOAT range (up to 1,600m²) uses dual-LiDAR navigation — see the full robot lawn mowers range.
