Vacuum has very weak suction even though the motor sounds normal.

Safety first: Turn OFF the vacuum and remove the battery before disassembly.

• 1. Check dust bin seal: Remove and reinstall the dust bin, ensuring it clicks firmly. Inspect the rubber gasket around the bin opening for damage.
• 2. Inspect cyclone: Look at the metal or plastic mesh inside the bin. If coated with fine dust, clean it with a soft brush or rinse if TCL allows washing (dry completely before use).
• 3. Examine wand and joints: Look for cracks or splits in the wand and ensure all joints fit tightly without gaps.
• 4. Verify filter placement: Make sure filters are installed in the correct order and orientation; missing filters can alter airflow.

If suction remains weak: The main motor fan or internal seals may be damaged. Professional service is recommended.
