Robot vacuum vibrates excessively and rattles when moving, especially on hard floors.

Safety first: Turn off the robot and place it upside down on a soft surface.

• 1. Inspect main brush: Remove the brush and roll it on a flat surface. If it wobbles or is visibly bent, replace it.
• 2. Check end caps: Ensure both brush end caps are present and seated correctly.
• 3. Tighten screws: Check the bottom cover and brush guard screws; tighten any that are loose.
• 4. Clean wheels: Remove debris from wheel treads and around axles to ensure smooth rolling.
