Robot vacuum repeatedly avoids certain areas or refuses to cross dark-colored rugs.

Safety: Turn OFF the robot.

• Clean cliff sensors: Wipe all underside cliff sensor windows with a soft, dry cloth.
• Lighting check: Reduce direct sunlight or strong spotlights on the problem area.
• Test on different surfaces: Verify that the robot behaves normally on light-colored floors.
• Virtual boundaries: If the robot cannot reliably cross a particular rug, consider setting a no-go zone in the app.
• If behavior worsens: The cliff sensor module may require replacement.
