Why does the Xiaomi Robot Vacuum X20 Pro Omni Station show an abnormal water level in the washboard?

If the washboard of your Xiaomi Robot Vacuum X20 Pro Omni Station displays an abnormal water level, please follow the troubleshooting steps below:
1. Clean the washboard thoroughly to remove any dirt or residue that can interfere with water level detection.
2. Reinstall the dirty water tank properly, ensuring it is securely in place.
3. Check that the sealing ring of the dirty water tank is correctly positioned and tightly fitted to prevent leakage or sensor misreading.
4. Inspect the metal water level detection contacts on the washboard for dirt or debris buildup, and rinse or wipe them clean with fresh water.
5. If the above steps do not resolve the issue, internal inspection can be needed to check whether any internal water pipes are loose or disconnected. It is strongly recommended to have a professional technician perform the disassembly and inspection to prevent accidental damage and ensure proper repair.
If the problem persists after all these checks, please contact the after-sales service center for professional assistance.
