Robot mowers got good fast — and confusing just as fast. Wire-free or buried wire? RTK, vision, or LiDAR? Will it hold a fix under your oak tree? Which "2.5-acre" claim is real? We built this to answer the one question that matters: which one fits your yard.
Specs are compiled from manufacturer spec sheets and published 2026 buyer testing, then normalized so you can compare like for like. Slope is the messiest spec in the category — makers quote degrees or percent grade, and ratings run optimistic — so we tier it (gentle / steep / very-steep-AWD) and tell you to verify your steepest section. We haven't lab-tested every unit; where we're relying on the maker's number, we say so.
When you buy through a link here, we may earn an affiliate commission at no extra cost to you (as an Amazon Associate we earn from qualifying purchases). We're also building a network of local install-and-maintain pros — if you'd rather not deal with setup, tell us your area. Affiliate relationships never change which mower we match you to; the finder ranks on fit, not commission.
