What reviewers found
Segway Navimow X350
- PCWorld (TechHive): On a challenging, sloped yard it navigated well day and night and cut as well or better than the i and H series. AI mapping failed on the slope and the front end slid downhill when driving across a slope. Setup took about 30 minutes; recharges took 60 to 90 minutes. Source
- TechRadar: On a 1,000 m² (0.25 acre) lawn with large trees it mowed fast and neat, stayed accurate under trees and respected no mow zones. It avoided a ride on toy and a soccer ball but ran over a tangerine sized ball. Sub scores: design 5/5, performance 4.5/5, app 5/5, value 4/5. 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
