How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting the unit. Do not use a vacuum with a cracked housing exposing internal parts.
- Visual inspection: Check the body, handle, and dust bin for cracks, gaps, or misalignment that may indicate internal damage.
- Reseat battery: Remove and reinstall the battery to ensure solid contact.
- Power cycle: Leave the battery out for 10 minutes, then reinstall and attempt to power on.
- Check for rattling: Gently shake the vacuum (battery removed). If you hear loose parts inside, internal components may be broken.
- Service recommendation: Internal sensor and PCB issues require disassembly and should be handled by a qualified technician. Continued use may be unsafe if the unit was heavily impacted.
