What does the MAX logo on the Xiaomi Vacuum Cleaner G20 Max transparent Dust Compartment mean?

When the dust reaches the "MAX" mark, continued use will affect the vacuuming effect, so please clean it as soon as possible before using it again. Remove the Extension Rod before cleaning the Dust Compartment, and ensure the power adapter is disconnected.
Note:
Before emptying the dust, please remove the Extension Rod and the accessory nozzle, align the Dust Compartment cover end with the trash can and press the Dust Release Button.
