A strong all wheel drive climber for big, sloped lawns that does not need RTK satellites, so it suits yards with trees and buildings. Testers found it reliable at navigation and covering the whole lawn, though it fell a bit short of its 80% slope claim. Skip it if your yard is small and tight, or if you need it to dodge small toys.
Best for: large, hilly lawns with poor satellite signal. Skip if: your yard is small with tight corners.

What independent reviewers found
- Tested the 3500: covered about 600 m² in roughly 4 h per charge, recharged from 15% to 100% in under 1.5 h, measured about 60 dB at 1 m, and showed a robot lifted error just over 70% on the slope ramp versus the 80% claim. Navigation was reliable but it sometimes touched obstacles lightly.
- Notebookcheck
- Tested the 3500 on a steep, dog damaged lawn and got a fast, even cut with easy setup and no docking problems. Obstacle detection was reliable for people and pets but is specified for objects above 5.5 cm, so small toys can be missed. Gave it Editors' Choice.
- M3 · 4/5
- Tested the smaller 2500 version and named it Best for Steep Slopes. AWD kept traction on slopes that slowed other mowers, and it handled thick St. Augustine grass. Category scores: Performance 5, Navigation 4.5, Value 3.5.
- Bob Vila
- Tested the A3 AWD Pro (listed with the 0.62 acre rating) for several weeks. Traction on steep, rough ground never needed a rescue and it stopped short of toys, a ball and dogs. Auto mapping was rough, and the edge mode's fixed 1.2 in height scalped the perimeter.
