What to do if the water overflow sensor electrodes of the Xiaomi Robot Vacuum X20 Max's omni station turn yellow?

The water overflow sensor electrodes on the omni station are used to detect the water level in the washboard. When the water level rises and is in contact with the electrodes, it begins to drain the dirty water, preventing overflow. This feature is particularly important in maintaining the safety and longevity of the device and ensuring efficient operation during mopping or other water-related tasks.
Since the electrodes are in contact with dirty water for extended periods, yellowing is normal and does not affect regular use. You can wipe them with a damp cloth before use.
