Vacuum leaves visible debris on carpets even after multiple passes

Safety first: Remove the battery before working on the floor head.

• Check floor mode: Ensure the vacuum is set to the appropriate mode for carpet (brushroll enabled).
• Inspect brushroll bristles: If bristles are worn down, soft, or uneven, replace the brushroll.
• Clean floor head channel: Remove the brushroll and clean the suction channel behind it.
• Adjust height (if applicable): Set the floor head to a lower height setting for deeper carpet cleaning.
