Why is there an odor or burning smell when using the Xiaomi Dust Mite Vacuum Cleaner?

During initial use, it is normal for the heat vents to emit hot air and a slight odor. This odor will dissipate over time with continued use.
If a burning smell occurs after extended use, it is due to dirt and blockage in the dust compartment or filter, preventing proper ventilation and causing overheating. Please follow the cleaning instructions for the dust compartment and filter, or replace them if necessary. Allow the device to cool down before using it again.
Note:
After cleaning the filter, ensure it is completely dry before reinstalling it to prevent blockage.
