Robot vacuum repeatedly avoids certain areas of the floor even though there are no visible obstacles.

Safety first: No internal access is required.

• 1. Observe floor type: Note if the avoided areas are very dark, glossy, or patterned. Some sensors misinterpret these as drop‑offs.
• 2. Adjust lighting: Reduce direct sunlight or strong reflections in the problem area and test again.
• 3. Clean cliff sensors: Wipe the underside cliff sensors with a soft cloth.
• 4. Use app tools: If your model supports it, adjust virtual boundaries to guide the robot differently or manually clean those areas.
