What to do if the Xiaomi Truclean W20 Wet Dry Vacuum experiences a false alarm or no alarm when the dirty water tank is full during use?

1. The water-full detection of the Xiaomi Truclean W20 Wet Dry Vacuum is achieved through a water level sensor. When stains or viscous liquids adhere to the sensor, it will affect the detection of the sensor, resulting in false alarms or no alarms;
2. While using the Xiaomi Truclean W20 Wet Dry Vacuum, the water in the dirty water tank is in dynamic flow, which is likely to accidentally touch the sensor and cause the illusion that the dirty water tank is full. At this time, the sewage in the dirty tank can be cleaned in time and the sensors on both sides can be cleaned and wiped clean to solve the problem.
