The electric brush bar of the Xiaomi Vacuum Cleaner G20 Max comes with over-current and over-temperature protection. If there is an obstruction or entanglement, or the motor temperature becomes too high, it will automatically stop as a protective measure to prevent potential dangers.
If the electric brush bar is not rotating, please refer to the below steps to troubleshoot:
1. Please check if there is any entanglement on the roller brush. If so, clean the foreign objects promptly;
2. Check if the working temperature is too high, as the motor has a high-temperature protection feature. Please wait for the brush head to cool down before use again.
