Vacuum leaves dust behind and does not pick up well from carpets

Safety first: Remove the battery before inspecting the floorhead.

• 1. Inspect brush roller: Check bristles for wear. If they are very short or uneven, replace the roller.
• 2. Clean floorhead: Remove debris from the suction channel and around the roller.
• 3. Check suction strength: Test suction at the handle with the floorhead removed. If strong, the issue is in the floorhead; if weak, clean filters and check for blockages.
• 4. Use appropriate mode: Ensure you are using the correct power level and floorhead for carpets (e.g. Electrobrush on higher power).
