In recent years, thanks to the growth of people's health needs and the in-depth understanding of mite removal devices, the development of my country's mite removal device market has entered the fast lane and ushered in a period of rapid growth, and the scale of demand has continued to expand. At present, mite removal devices can be used to clean dust, mites and other allergens on textile items such as beds, sofas, carpets, and clothing. When using a mite removal device for cleaning, the suction port on the bottom contacts the cleaned surface, and a strong suction force is generated through the fan device. With the cooperation of the roller brush, dust, mites and other dirt on the cleaned surface are sucked into the mite removal dust cup for filtration and separation, thereby achieving the cleaning purpose.
