How to Fix / Troubleshooting
Safety first: Remove the battery and disconnect the charger before any inspection.
- Check battery in another device (if compatible): If you have another compatible iRobot cordless vacuum, test the battery there to confirm it is good.
- Inspect for odor or heat: Smell near the motor vents and PCB area (if accessible) for burnt odor. Do not continue using the unit if you detect burning.
- Hard reset: Remove the battery for 5 minutes, then reinstall and hold Power/Clean for 20–30 seconds to attempt a full reset.
- Try charging cycle: Place the vacuum on the charger for at least 2 hours, then attempt to power on again.
- Service main board: If Err 10 persists and the unit never fully powers up, the main PCB or power regulation circuitry is likely defective and requires replacement.
