Prices: YARDCARE M800Plus — Amazon US price checked October 10, 2026; ECOVACS GOAT O1000 RTK — Amazon US price checked October 10, 2026.
Budget wire-free mower using GPS plus a camera, with row-then-random mowing and 35% slope handling.
Verdict: A well-reviewed budget pick for open lawns. Standard GPS isn't centimetre-accurate like RTK, so expect a partly random pattern rather than perfect stripes.
Budget ECOVACS mower for up to 1/4 acre using RTK plus vision and 3D ToF, with TruEdge edge cutting.
Verdict: A lot of mower for the money from a major brand. Choose the LiDAR PRO version instead if trees or buildings block satellite signal.
