- Wire-free at a mid-range price
- Independent proof
ANTHBOT M9: What bothers us
- Leaves an uncut strip along borders, in corners and around obstacles, so edges need trimming by hand (PC-Welt, netzwelt)
- In PC-Welt's test it got wedged between chair legs and tore up turf; on uneven slopes it sometimes got stuck (netzwelt)
- Satellite navigation can struggle under heavy shade from trees or buildings (netzwelt)
- 4G and NetRTK are free only for a trial period; PC-Welt names €39.99 a year for 4G remote control
Ecovacs GOAT O800 RTK: What bothers us
- Narrow 22 cm cut, suited to smaller lawns
- Only 45% slope capability
- Warentest found widespread weaknesses in safety and obstacle tests across the field and advises mowing in daytime only
