The Best Robot Lawn Mowers for UK Gardens

Choose in Four Questions

1. How big is the lawn? Measure the grass only, in square metres. Pick a mower rated above it. The lawn-size calculator does the sums and lists matching models.
2. How steep is the steepest part? Most models under £1,000 are rated somewhere between 25% and 45%. Anything steeper narrows the field quickly; our slopes guide shows how to measure it with a phone.
3. Wire or no wire? A boundary wire works anywhere but takes an afternoon to lay. Wire-free models use satellites, cameras or LiDAR, each with a weak spot. Read wire vs wire-free.
4. One lawn or several? If the mower must reach a front lawn too, check how it gets there. See front and back gardens.

Our Six Picks

Each pick links to the full guide for that garden type, where you will find alternatives, owner praise and complaints, and the reasons to skip it.

Every Model We Track

All 25 models in our database, sorted by rated area. Model names link to the manufacturer's UK page or the UK retailer we used.

Figures are from the manufacturer's UK page where published, otherwise from the retailer or source linked from the model name, checked 28 October 2026. "Not stated" means we found no published figure. Prices are the brand's UK price unless labelled otherwise, and retailers' prices change often.

What to Know Before You Buy Any Robot Mower

Daytime Only, for Hedgehogs

Hedgehog Street, run by two UK wildlife charities, advises running robot mowers only in daylight and checking the lawn first. Our hedgehog safety guide explains the research behind that advice.

Edges Still Need Trimming

One of the complaints we see most often in the owner reviews we read, across brands, is that edges and corners are not cut as close as owners hoped. Budget a few minutes with a strimmer every couple of weeks, or look at a model with an edge trimmer.

Line-Ups Change Every Spring

Brands refresh their ranges regularly, and models sell out. We re-check every guide before the mowing season. The "last checked" date at the top of each page tells you when we last did.

Is It Worth It?

For many households, a robot mower replaces a gardener's mowing visits or a weekly hour behind a mower. Our five-year cost comparison shows when the numbers work.
