What reviewers found
Segway Navimow X315
- Notebookcheck: Stable RTK and straight passes on two test areas. Detected a hedgehog dummy and a hose but missed a small tennis ball once in three tries. Ran about 2 hours per charge, recharged in about 1 hour, measured about 55 dB. Left at least 10 cm uncut at edges and did not reliably climb a 50% ramp. Verdict: almost perfect. Source
- PC-Welt: Editors' Choice. On a 120 m² lawn it set up in minutes, mowed in changing lanes and reached edges well, with rear wheels gripping on gravel. First passes left narrow uncut strips that cleared on later runs. Random obstacles were detected reliably; about 60 min to charge. Source
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
