Why Cleaning Filters in Xiaomi Vacuum Cleaners and How Often

Xiaomi vacuum cleaners, from the compact Mi Handheld to the powerful Roborock robot vacuum cleaners, require regular filter maintenance.

HEPA-The filter can release up to 70 percent of the microbes it was supposed to trap, and in models with aquafilters (like Dreame). V12) Contaminated water becomes a source of unpleasant odor after 2-3 uses.

The manufacturer recommends cleaning filters after every 3-5 cleaning cycles (for hand vacuum cleaners) or every 1-2 months (for robots). But these figures are conditional: if you remove construction dust, pet hair or work in high humidity, the interval is reduced to 1-2 weeks. The main sign that the filter requires cleaning is that the vacuum cleaner begins to buzz louder, loses suction power and smells of dampness or burn.
