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
Sunseeker X5 Gen 2
- inside digital: Mixed verdict. Edge cutting was praised and the six blade floating deck cut cleanly, but it missed a garden hose and refused to mow where network RTK signal was weak in a city garden. Its IPX5 rating was the lowest in the comparison. Source
- instalki.pl: Positive verdict after two weeks on a 337 m² flat lawn: about 122 m² per hour, about 100 minutes per charge, about 60 dB, no escapes from the map. It left about 8 cm uncut along walls versus 3 cm claimed and hit a small ball and a porcelain snail. Source
