If your Xiaomi Ultra Light Vacuum Cleaner suddenly stops working, here is a general guide for your reference to troubleshoot the issue:
1. If your device runs out of its battery, it will stop working. Please check your battery level and fully charge the device, then resume use to check if the issue persists;
2. The vacuum comes with an overheat protection mechanism. The device will turn into the overheat protection mode if it works for a long time and the motor is overheated. Please check and clear any blockages and cool down the device motor, then restart the vacuum to check if it works;
3. Check if its suction port or airway inlet is blocked. Please clear any blockages from the suction port or airway inlet.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
