The clean water tank for the MACH vacuum cleaner may look small but it actually has a large capacity. The capacity of the clean water tank is 820ml, which can hold enough water to easily clean a total area between 150-200m²（1614-2153 ft²).

If the size of the home is larger than the aforementioned area, it is recommended to start the vacuum's self-cleaning process after using a full tank of clean water, then resume cleaning after the vacuum cleaner completes its self-cleaning process.
