How to Fix / Troubleshooting
Safety first: Ensure the robot is on a stable surface and not cleaning.
Step-by-step:
- Update firmware: Use the Eufy app to check for and install the latest firmware.
- Recreate schedules: Delete all schedules and reprogram them after firmware update.
- Stable charging: Ensure the charging base remains plugged in and the robot stays docked when not in use.
- Advanced repair: If settings still reset, the main control board may have a failing memory chip or RTC circuit and will likely need replacement.
When to stop: Board-level memory repair is not user-serviceable; replace the board or seek professional help.
