Robot mowers for steep hills

Of 47 US models we track, 23 fit this yard, 1 can't be confirmed from what the manufacturer publishes, and 23 are ruled out.

A 45% slope is about 24°. Manufacturers quote slope in percent or degrees, so we convert everything to percent before comparing. A rated slope is the maker's claim, not a test: wet grass and loose ground can reduce grip.
