Robot vacuum vibrates excessively or bounces during operation, especially on hard floors.

Safety first: Power off and flip the robot over.

Step-by-step:

• Inspect main brush: Remove and roll it on a flat surface. If it wobbles or is visibly bent, replace it.
• Clean brush thoroughly: Remove all debris from bristles and end caps.
• Check brush guard: Ensure the guard is not cracked and is latched securely.
• Inspect wheels: Spin each wheel and look for flat spots or wobble. Replace the wheel module if damaged.

After reassembly, test on a small area to confirm vibration is reduced.
