Robot vacuum repeatedly bumps into furniture harder than before or fails to slow down before obstacles.

Safety first: Power off the robot before cleaning sensors.

Step-by-step:

• Clean front sensors: Wipe the front IR sensor windows and camera lenses with a soft, dry cloth.
• Check bumper movement: Press the bumper to ensure it moves freely and returns evenly.
• Adjust lighting: Avoid running the robot in very bright direct sunlight that can saturate sensors.

If collision behavior remains abnormal, the front sensor board or camera module may be failing and require replacement.
