This list is for large lawns, and a mower qualifies if the brand rates it, or its largest version, for 1 acre or more. Some models come in several sizes, so make sure the version and price you pick cover your lawn. Compare deck width and runtime too, since a big lawn takes many charges to finish. How we score.
LiDAR, vision and NetRTK flagship for steep, complex lawns
Did better than the mini 2 in published tests, with 5/5 for performance from TechRadar and 4.5/5 from Gear Diary, but its higher price pulls it level at 8.0. It sits well clear of the Dreame A3 on test results. Reviewers flagged front wheel scuffing during zero turns and app glitches.

Four wheel drive RTK and vision mower for complex yards up to 1 acre
Rated for 1 acre and 84% slopes, with four wheel drive and a 17 in deck. Bob Vila named it Best Overall and PCWorld gave it Editors' Choice, but neither published a numeric score, so it is not ranked yet. It is also large, heavy and among the priciest mowers here.
