How to Fix / Troubleshooting
Safety first: Turn OFF the vacuum, remove the battery, and disconnect from charger before working on controls.
- Check for physical obstruction: Inspect around the trigger or button for dirt or debris. Clean with a dry cloth or compressed air.
- Test actuation: Press the trigger repeatedly and note if it feels sticky or fails to click. A mushy feel suggests internal damage.
- Try reset: Reinstall the battery and perform a reset (hold Power/Clean 10–20 seconds). Test again.
- Replace switch assembly: If the trigger remains intermittent, the internal switch or trigger mechanism likely needs replacement, which requires opening the handle housing.
