If the Xiaomi Dust Mite Vacuum Cleaner 2 Pro experiences reduced suction, excessive noise, or shuts down automatically and stops working, these issues could be caused by one or more of the following conditions. Please make sure to promptly clean out any debris. If any components have been washed, ensure they are completely dry before reassembly, as residual moisture can damage internal electronic components.
The causes are as follows:
The dust compartment is full of dust and debris.
The air inlet filter is clogged with dust.
The HEPA filter is overloaded with dust.
The suction port is blocked.
The vacuum has been left running on a soft surface (e.g., bedding) for too long.
The roller brush is tangled with debris, or the rubber strip on the brush is loose.
The power plug is loose, unplug and reconnect it, then restart the device.
