Robot Mowers for 1 Acre, 2 Acres and Large Lawns
Which models their makers rate for an acre or more, why those ratings cannot be compared from one brand to the next, and how to size a mower for your own lawn.
AcreMower
Robot lawn mowers, explained from the makers’ own figures
What size of lawn each model is rated for, how the wire-free ones find their way, what they cost and how one brand’s models differ from each other. Every figure points back to whoever published it, usually the maker, and every price carries the date we checked it.
Five guides so far. We do not test mowers, so you will not find verdicts, scores or best-of lists here.
Start with your lawn
Two numbers decide most of the choice: the lawn size a mower is rated for, and what it costs.
Buying guide
How Much Does a Robot Lawn Mower Cost?
Prices on the makers’ US stores, grouped by the lawn size each model is rated for, and the costs beyond the sticker price: 4G and RTK subscriptions, boundary wire, blades and installation.
How they navigate, and how the models compare
One guide to the mowers that work without a boundary wire, and one guide per brand.

Before you buy
Robot mower prices change often and models sell out. The cost guide groups the makers’ own US store prices by lawn size, for the models in stock on the day we checked. When a guide links to Amazon, the link opens a search for the model rather than a listing we picked.

How this site works
Every figure has a source
Lawn size ratings, slope limits, run times and prices each point back to whoever published them, usually the maker’s US product page, comparison chart or owner’s manual.
No tests, no rankings
We have not run these mowers on our own lawns, so we publish no verdicts, scores or star ratings. We compare what the makers publish and say whose figures they are.
Prices with a date
Prices change and models sell out. Every price in a guide says the day we checked it and where, which is usually the maker’s own US store.
