Vacuum leaves fine dust on hard floors even after multiple passes.

Safety first: Turn OFF and remove the battery before changing heads or inspecting seals.

• 1. Use correct head: If your TCL vacuum includes a soft roller head for hard floors, install it instead of the carpet head.
• 2. Inspect front seal: Check the rubber lip or squeegee at the front of the floor head. Replace the head if the seal is torn or missing.
• 3. Clean filters: Ensure pre-motor and HEPA filters are clean to maximize suction.
• 4. Slow, overlapping passes: Move the vacuum slowly and overlap passes to capture fine dust.

Result: Correct head selection and good suction typically resolve poor hard floor pickup.
