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 X450
- PCWorld (TechHive): Testing the X430 sibling, it climbed an uneven, sloped yard without spinning, sliding or stalling, stayed inside the boundary around trees and a play set, and did not slip over a raised edge where the i215 had. Editors' Choice; cons were price, size and weight. Source
- Expert Reviews: Testing the X4 series (X430 unit), it praised grip on 40° slopes, gravel and kerbs and easy setup. The first pass was very good, the second excellent, and it stayed 5 to 10 cm from beds. It ran about 150 min per charge and measured 68 dBA. Source
