Robot lawnmower leaves uncut strips of grass or misses areas of the lawn.

Safety first: Turn the mower OFF before inspecting blades or wiring.

• Check blades: Turn the mower on its side and verify that all pivoting blades are present, sharp, and free to swing. Replace missing or dull blades with genuine Stihl blades.
• Review layout: Compare your perimeter and guide wire layout with the Stihl installation guide. Ensure narrow passages are wide enough and that the guide wire leads through remote areas.
• Increase mowing time: Extend the daily mowing schedule so the mower has enough time to cover the entire area, especially for larger lawns.
• Remove obstacles: Relocate garden furniture, toys, or hoses that may block the mower from reaching certain zones.

After adjustments, monitor the mower over several days to confirm improved coverage.
