Generally, the washing machine needs to be used for a period of time, or often after washing hairy clothes and dirty clothes, there will be more wool and dirty debris in the filter screen inside the machine, which should be taken out for cleaning and washing. If there is too much dirt in the filter screen, it will affect the cleanliness of the washed clothes surface. Generally, the filter screen inside the machine is too dirty or even too full to filter lint and dirt. It is recommended to take it out and clean it before use. Some filters are in obvious places.

Washing machine is a kind of clean electric appliance that uses electric energy to generate mechanical action to wash clothes. According to its rated washing capacity, it can be divided into two categories: household use and collective use.

China stipulates that the washing capacity below 6 kg belongs to domestic washing machines: domestic washing machines are mainly composed of box, washing and dewatering barrels (some are separated), transmission and control systems, and some are equipped with heating devices. Washing machines generally use water as the main cleaning liquid, which is different from using special cleaning liquid and dry cleaning which is usually handled by special personnel.
