How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting the handle or trigger area.
- Check for physical damage: Inspect the trigger for cracks, looseness, or misalignment. Ensure it returns smoothly when released.
- Try different modes: Some models have a separate power button and trigger. Test all controls to see if any response occurs.
- Reset the unit: Remove the battery for 1–2 minutes, then reinstall and test again.
- Limited user repair: The trigger switch and handle PCB are internal components. If the trigger feels normal but the vacuum does not respond, the handle assembly likely needs replacement by a technician.
