What to do if the dust compartment of the Xiaomi Dust Mite Vacuum Cleaner cannot be installed?

If the dust compartment cannot be installed, it is due to improper installation methods or damage to the latch.
You should align the triangular notch on the dust compartment assembly with the triangular protrusion on the main unit. Push the dust compartment assembly into the main unit until you hear a "click" sound, indicating that the dust compartment assembly is securely installed in place.
