Vacuum leaves debris on carpet even though the brush roll spins.

Safety first: Turn OFF and remove the battery before inspecting the floor head.

• 1. Inspect bristles: Remove the brush roll and check bristle length. If they are flattened or very short, replace the brush roll.
• 2. Clean suction channel: Look behind the brush roll into the suction opening and remove any packed debris.
• 3. Use correct head: Ensure you are using the TCL motorized carpet head (if your model includes multiple heads) on carpets.
• 4. Slow passes: Move the vacuum more slowly over the carpet to allow the brush and suction to work effectively.

Result: Replacing a worn brush roll and clearing the suction channel usually restores pickup performance.
