Robot vacuum repeatedly avoids certain areas or stops at edges of dark rugs

Safety first: Ensure there are no actual drop‑offs where the robot is operating.

Step-by-step:

• Clean cliff sensors: Wipe all underside cliff sensors with a soft cloth.
• Increase lighting: Turn on room lights to improve sensor performance.
• Test on lighter surfaces: Move the robot to a room with lighter flooring to confirm normal operation.
• Use boundary strips: If the robot will not cross a dark rug, consider using boundary strips to exclude that area or manually vacuum it.

Some ILIFE models have limited ability to handle very dark or glossy floors; this is a design limitation rather than a repairable fault.
