How to Fix / Troubleshooting
Safety first: Ensure the robot has sufficient battery before performing resets.
- Update firmware: Open the Ultenic app and check for firmware updates. Install any available updates with the robot on the dock.
- Reset maps: In the app, delete existing maps and allow the robot to perform a full new mapping run.
- Factory reset: If issues persist, perform a factory reset from the app or using the hardware buttons (refer to manual). This will erase all settings and maps.
- Test mapping: Run a full cleaning cycle and confirm if a new map is saved.
- If E19 remains: The main control board flash memory may be failing, requiring board replacement.
