Vacuum leaves visible debris on carpets even after multiple passes.

Safety first: Turn off and remove the battery before working on the brush head.

• Check brush rotation: Run the vacuum and observe whether the brush spins. If not, inspect for jams or motor failure.
• Inspect bristles: If bristles are worn down or uneven, replace the Main Brush.
• Clean floor head: Remove any lint or hair from the brush housing edges that may prevent full contact with the carpet.
• Verify suction: Ensure filters are clean and airflow is not restricted.
