Answer two quick questions and we will match you with our top-rated picks.
1. What is your budget?
2. What matters most?
Robot mowers have changed a lot in the last three years. Until recently almost every model needed a thin boundary wire pegged around the lawn. Now most new mowers from Segway Navimow, Mammotion, Ecovacs, Eufy and others find their way using satellites, cameras or lasers, and you set the edges by driving the robot round with your phone.
This hub covers both US yards (measured in acres and square feet) and UK gardens (measured in square metres). Start with the size of your lawn and how steep it is, because those two numbers decide which robots are worth looking at. Then choose a navigation type that suits your trees, buildings and phone signal.
Jump straight to a guide: best robot lawn mowers overall, wire-free models, 1 acre and bigger, hills and slopes, small gardens or the cheapest options.
| Type | How it finds the edge | Typical price | Good for | Watch out for |
|---|---|---|---|---|
| Perimeter wire | Buried or pegged cable | From around £380 (UK) | Simple, open lawns on a budget | Installation time, wire breaks |
| RTK GPS | Satellite plus correction signal | From around $549 / £449 | Open lawns with clear sky | Tall trees and buildings blocking signal |
| Vision (cameras) | AI recognises grass and edges | From around $1,400 / £1,499 | Simple layouts, easy setup | No mowing in the dark |
| LiDAR | Laser map of the garden | From around $999 / £999 | Trees, shade, narrow passages | Higher price, fewer budget options |
| Hybrid (two or three) | Combination of the above | From around $849 / £799 | Most lawns | Cost rises with features |
Verdict: The X430 combines network RTK and cameras, so there is nothing to install apart from the dock. Its 84% slope rating and 43 cm cut make it one of the most capable mowers on sale in both the US and UK. It is overkill for small gardens.
Verdict: LiDAR means it does not rely on satellites, so trees and walls are less of a problem. The built-in trimmer is the standout: BGR's reviewer said it replaced most of their manual edging. Confirmed US pricing only.
Verdict: Camera-only navigation keeps setup simple, and independent reviewers consistently praise how easy it is. It cannot mow at night and is not for steep slopes.
Verdict: All-wheel drive, no antenna and a sub-$900 / £800 price make this a sensible first robot. The narrow cut means it is best kept to smaller lawns.
Verdict: There is no dock and no app, so it is closer to a self-driving push mower than a true robot. For a tiny lawn at around £299 that may be all you need.
A robot mower is a small, battery-powered mower with razor-style blades on a spinning disc. Instead of one weekly cut, it trims a few millimetres often, sometimes daily. The clippings are so short they fall into the lawn and act as a light feed, so there is nothing to collect.
When the battery runs low, the robot drives back to its charging dock, recharges and carries on. You control schedules, cutting height and no-go zones through a phone app on most models. Safety features include blades that stop when the mower is lifted or tilted, and PIN codes or GPS tracking to deter theft. Consumer Reports says all its recommended models scored top marks for safety.
Older and cheaper robots follow a perimeter wire: a thin cable you peg around the edge of the lawn that tells the mower where to stop. Newer wire-free robots work out where they are in one of three ways:
Most premium mowers now combine two or three of these so one can cover for another.
For a deeper comparison see our guide to the best robot lawn mowers without perimeter wire.
Manufacturers rate each model for a maximum lawn area. US listings use acres or square feet, UK listings use square metres. Buy a mower rated for at least 20% to 30% more than your lawn, because ratings assume ideal conditions: flat ground, short grass and long mowing hours.
| Lawn size (US) | Square feet | Square metres (UK) | Rough picture |
|---|---|---|---|
| 1/8 acre | 5,400 sq ft | 500 m² | A large back garden |
| 1/4 acre | 10,900 sq ft | 1,000 m² | A large suburban lot |
| 1/2 acre | 21,800 sq ft | 2,000 m² | A bit over a quarter of a football pitch |
| 1 acre | 43,560 sq ft | 4,047 m² | Just over half a football pitch |
Quick maths: square metres x 10.76 = square feet. 1 acre is about 4,000 m².
Slope ratings are given as a percentage, in degrees, or both, and they are not the same thing. A 45% slope is about 24°. An 80% slope is about 38.6°. Most two-wheel-drive mowers stop around 45% (24°). All-wheel-drive models such as the Mammotion LUBA 3 AWD (80%) and Segway Navimow X430 (84%) go much steeper. See best robot lawn mowers for slopes.
Consumer Reports says the robots in its ratings range from about $800 to more than $2,500. In October 2026 we found:

A note for US buyers. On 28 July 2026 the US Federal Communications Commission (FCC) added foreign-made "advanced robotic devices" to its Covered List, and its FAQ confirms robot lawn mowers count. According to the law firm K&L Gates and Techlicious, models that were already approved can still be imported and sold, and mowers you already own are not affected. The rule mainly blocks new foreign-made models from getting approval, so some newer models may be slow to reach US shops. UK buyers are not affected.
Yes, on a lawn that suits them. Independent testers such as Consumer Reports and Reviewed found the best models give an even, frequent cut and handle obstacles well. They are less good at edges, very long grass and very complex layouts, so expect a little trimming.
The main ones are cost, setup time, uncut strips along edges, poor performance in long or wet grass, and the need to clear the lawn of toys and debris. Satellite models can lose signal under trees, and camera-only models cannot mow in the dark.
A good wire-free mower for a small to medium lawn costs around $850 to $1,500 / £800 to £1,500 in October 2026. For an acre or steep ground, budget around $2,400 to $3,000 / £2,100 to £2,900.
It depends on cutting width and speed. Ecovacs, for example, quotes 250 to 400 m² (about 2,700 to 4,300 sq ft) per hour for its GOAT A3000 LiDAR Pro, which works out at roughly 10 to 16 hours of mowing for an acre spread over several days. Robots are designed to run little and often, so that is normal.
Manufacturers do not publish a standard lifespan. The parts that wear are blades, which are cheap and replaced often, and the battery, which loses capacity over time. Check the warranty length and whether replacement batteries are sold before you buy.
Not with most new models. RTK, vision and LiDAR mowers use virtual boundaries drawn in an app. Wired models are still the cheapest option and work well on simple lawns.
