Robot vacuum frequently avoids dark rugs or stops at dark floor patterns

Safety: Turn OFF the robot.

• Clean cliff sensors: Wipe all downward-facing sensors with a soft, dry cloth.
• Lighting adjustment: Try running the robot with different room lighting (dimmed or curtains closed) to see if behavior improves.
• Rug repositioning: If possible, move very dark or black rugs away from stairs and high-risk areas.

Persistent issues may require cliff sensor module replacement or using physical barriers to protect problem areas.
