The Auto Clean mode on the Mijia Air Conditioner Pro Eco A+++ 12K performs a thorough self-cleaning process focused on the evaporator, which is prone to dust and moisture buildup.
During Auto Clean, the system cools the evaporator to condense moisture and trap dust, then lowers the temperature further to form frost that captures more dirt. It then gently warms the evaporator to melt the frost and wash away contaminants, followed by blowing warm air to dry the interior, preventing mold and keeping the unit clean.
This process helps improve air quality, reduce odors, and extend the air conditioner's lifespan.
