Vacuum leaves dust behind on carpets even though suction feels strong

Safety first: Remove the battery before working on the nozzle.

• Step 1 – Inspect brushroll bristles: Remove the brushroll and check bristle length. If they are worn down or uneven, replace the brushroll.
• Step 2 – Confirm brush operation: Reinstall the brushroll, refit the battery, and verify that the brush spins when the vacuum is on carpet mode.
• Step 3 – Use correct tool: Ensure you are using the motorized floor nozzle on carpets, not a passive tool.

Replacing a worn brushroll typically restores cleaning performance.
