1. If the tire is covered by a lot of mud or grass clippings, it could lose its traction. Clean the tire.
2. Check if the mowing boundary is set on a slope. If so, adjust the boundary, and make sure the slope along the boundary does not exceed 10%.
3. Check if the charging station or antenna is covered or blocked. If so, remove all obstacles covering, blocking, or surrounding the charging station or GNSS antenna.
4. Check if there is any item blocking the surface of the mower. Remove the obstacle.
If possible, installing a Vision Fence also can help the mower work within the boundary.
If the problem persists after that, please contact navimowsupport-us@rlm.segway.com for help.
