How to Fix / Troubleshooting
Safety: Disconnect from charger before handling.
- Check charger and outlet: Confirm the charger and outlet are working by testing with another device or charger.
- Try a different battery: If possible, install a known‑good battery. If the vacuum powers on, replace the original battery.
- Inspect for damage: Look for signs of impact, cracks, or liquid damage on the main body.
- Service main body: If there is still no response with a good battery and charger, the internal electronics or trigger are likely faulty and require professional repair or main body replacement.
