What to do if the 2-in-1 Brush Nozzle of the Xiaomi Vacuum Cleaner G20 does not rotate?

A: 1. Verify that the 2-in-1 Brush Nozzle is securely attached to the vacuum cleaner's wand or hose. A loose attachment could prevent the brush from rotating properly;
2. Inspect the brush nozzle and its rotating mechanism for any debris, hair, or obstructions that may be preventing it from rotating. Clean out any blockages carefully;
3. Examine the roller brush within the 2-in-1 Brush Nozzle. Ensure that it spins freely when manually rotated. Clean the roller brush thoroughly to restore proper rotation if it is tangled with hair or debris;
4. Please check if the operating temperature is too high. The motor should be protected against high temperatures. If so, please wait for the brush head temperature to return to normal before using it.
