Overview
WORX builds this Landroid around vision AI that recognizes obstacles, maps the lawn and finds edges without a boundary wire. Wheel brushes clear grass from the wheels as it drives, and an app handles control.
Cloud based positioning removes the on-site antenna that other robots need, and the brushes reduce wheel slip and cleaning. The slope rating is modest, and the narrow deck means the machine is best for smaller yards.
Who it's for
Owners of quarter acre lawns who dislike boundary wire and routine wheel cleaning are the fit. Hilly yards should look at all wheel drive models with higher slope ratings.
Pros and cons
- Wire-free vision navigation
- No on-site antenna needed
- Wheel brushes reduce build-up
- Tool-free installation listed
- Two wheel drive limits slope work
- Narrow cutting width
- Rated for small lawns only
Performance notes
Cameras and AI recognize obstacles and edges, while a cloud RTK signal fixes position without a local antenna. Shade can degrade satellite signals, which is why the description credits camera mapping in shaded areas. Brushes at the wheels limit grass packing that causes slipping.
