Set up in an hour, not a weekend
Walk the mower round your edges with the app, drop the charging station by a socket, and you are more or less done. Redrawing a flower bed no longer means re-laying cable.
Wire-free robot mowers, compared calmly
Most robot mower advice assumes a big, flat, rectangular lawn in full sun. Real gardens are small, sloping, shady and full of corners. We compare the wire-free mowers built for gardens like yours — satellite, LiDAR and camera models side by side, from the manufacturers' own figures.
Honest from the off: we compare specifications and published data, not hands-on tests. Here's exactly how we do it.


Not sure where to start?
Six questions about your plot — its size, its slopes, its shady corners — and the Mower Finder matches you to the wire-free model whose specifications fit it best, with the reasoning shown and any shortcoming named. A minute, no email address, nothing leaves your browser.

Walk the mower round your edges with the app, drop the charging station by a socket, and you are more or less done. Redrawing a flower bed no longer means re-laying cable.
Because these mowers know where they are — rather than bumping about at random — many mow in orderly stripes and cope far better with narrow passages and odd corners.
New patio, new raised bed, a trampoline that migrates with the sun: adjust the map on your phone. Try doing that with 150 metres of buried wire.
If you read nothing else: the sensible all-rounder for small lawns, the climber for banks, and the clever one for shady gardens where satellites struggle.

Gardens where satellite signals are patchy — shade, trees, tall fences.
Check priceA small lawn is not a lesser lawn — it is simply the size most of us actually have. The trick is matching the mower to the plot: satellite models want open sky, LiDAR models shrug off shade, and camera models ask for the least installation of all. Our small-yards guide works through the sums garden by garden.
Slopes deserve respect, too. A mower rated for gentle inclines will sulk on a proper bank, and no specification yet written can repeal gravity. We flag the honest slope rating of every model we list — including the one machine here that climbs like a goat.
