What reviewers found
Husqvarna Automower 435X AWD
- Tom's Guide: Tested on a front lawn sloping about 25°. The first unit threw collision and docking errors after a week and needed a motor replacement; the replacement ran flawlessly for two months, including through about 10 in of rain. Random cut pattern, very quiet. Source
- PCWorld: Three months of testing. Pro install took under an hour on a small yard. About 100 min runtime and 30 min recharge, rated 62 dB and barely audible, never left the perimeter. A dip in the yard had to be filled for an even cut. Source
Segway Navimow X390
- Pro Tool Reviews: Tested the X390 on a multi acre property with 4 zones and 3 channels. Mapping took under 30 min, it handled narrow paths, wet grass and minor slopes without slipping and dodged toys and beds. Early passes left uneven spots that improved later, and a hilly, thick grass run covered 43% (6,131 sq ft) before a recharge. Source
- Notebookcheck: Testing the X3 series (X315 unit), it called the line one of the best robot mowers of 2025: reliable mowing, systematic paths and near flawless camera obstacle detection. Downsides were high standby power use, the need for an RTK antenna and a high price, with the X390 listed at $4,999 RRP. Source
