Cause:
The mower cannot detect the lawn boundary because it is unclear (slopes, uneven ground, curbs, debris, or overgrown grass).
Solution:
Keep the border flat and even.
Remove leaves, debris, or overgrown grass.
Make the boundary more visible if needed: barriers, magnetic strips, or treating patchy grass.
Cause:
The mower cannot follow the magnetic strip because it is installed incorrectly or covered.
Solution:
Keep strip at least 32 cm from the edge.
Do not bury it.
Install on flat grass.
Remove leaves or obstacles.
Cause:
The mower was placed or started outside the mowing area.
Solution:
Always start inside the mowing area near the charging base.
Do not start from gravel, paths, or outside the lawn.
Cause:
The mower leaves the mowing area due to steep edges, holes, narrow passages, or slipping on wet grass.
Solution:
Fill in holes or make them smooth.
Avoid steep drops.
Widen narrow passages.
Operate on dry grass.
Clean wheels and check treads.
Cause:
Poor lighting (too dark, strong shadows, or glare) prevents border detection.
Solution:
Use mower in daylight.
Avoid very dark or glaring conditions.
Adjust schedule to brighter times.
Clean camera lens.
