Possible Causes
Weak or aged battery pack, Overheating main motor, Partially blocked airflow causing high load, Loose internal power connector between battery and PCB
How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting for blockages.
- 1. Fully charge battery: Charge until the battery indicator shows full, then test again.
- 2. Clean filters and bin: Empty the dust bin and clean both pre-motor and HEPA filters as per TCL instructions.
- 3. Check for clogs: Inspect the wand, floor head, and all inlets for obstructions and remove any debris.
- 4. Test without attachments: Run the main body alone. If it stays on, the issue is likely in the wand or floor head.
- 5. Cool-down period: If the vacuum feels warm, let it cool for 30 minutes and then retry.
Next step: If the vacuum still shuts off quickly with clear airflow and a fully charged battery, the battery or main motor may be failing and should be replaced.
