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 X430
- Bob Vila: Named Best Overall. Handled thick St. Augustine grass and steep side yards better than the other six mowers tested; mapping was the easiest in the group; the RTK antenna was never needed. Source
- PCWorld (TechHive): Editors' Choice. On a 7,600 sq ft test lawn it stayed inside boundaries, climbed slopes without slipping and did not go over a raised edge that a smaller Navimow fell into; cut was even at 3 and 4 in. Source
