What reviewers found
Husqvarna Automower 435 iQ AWD
- M3 (3.5/5): Tested the 435X AWD NERA, the European model with the same listed specs, for four weeks on a hilly 3,000 m² multi zone lawn. AWD handled the steepest parts; random mowing covered the lawn in 3 to 4 days; it got stuck once. Ran over water bottles and tennis balls, and does not cut close to edges. Source
- Tom's Guide: Tested the older wire guided 435X AWD on a lawn sloping about 25°. The first unit had collision and docking errors and needed a new motor; the replacement kept working through about 10 in of rain. Very quiet. 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
