Robot vacuum leaves hair and debris along wall edges and corners.

Safety first: Turn OFF the robot and flip it over.

• Check side brush: Ensure the side brush is installed, not missing, and that its bristles are not bent or worn flat. Replace if needed.
• Clean hub: Remove the side brush and clean hair from the hub and shaft.
• Verify speed: Run the robot briefly and observe side brush rotation. If it is slow or intermittent, the side brush motor may be weak and need replacement.
• Use edge mode: If available in the app, enable an edge-cleaning pass to improve wall coverage.
