What reviewers found
eufy E18
- PCWorld (TechHive): On a small but complex yard it was running in under 30 minutes and mapped about 400 sq ft in under 10 minutes. Cut was even from the first mow, but slopes needed no go zones, tall weeds were flagged as obstacles, and glare and walkway stones confused it. Rear wheel drive felt underpowered. Source
- Freshly Charged: Setup took about 10 minutes and mapping about 45 minutes, the fastest the site had tested. Detected and avoided toys, furniture and a dog, then went back to mow the missed area. Ran up to 26° slopes without issues; battery drained relatively quickly on larger yards. Source
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
