What to do if the Xiaomi Truclean W30 Pro Wet Dry Vacuum roller brush occasionally reports "brush entanglement" when in use?

Question

Accepted Answer

The reasons for the roller brush of the Xiaomi Truclean W30 Pro Wet Dry Vacuum to be entangled are as follows:
This happens because the new roller brush has long fluffy fibers. When the clean water tank is full, the added weight reduces clearance between the tank and roller brush , causing slight contact when the roller brush is still dry.
The solutions are as follows:
In the event of a malfunction, simply power the device off and on in normal. The initial strong water flow will moisten the roller brush, and once the brush fibers soften and flatten slightly, normal floor cleaning can proceed. You can also perform a self-cleaning cycle.
Note: 
The reduction in fluffiness of the brush after being moistened will not affect the cleaning performance.
