1 First of all, we can choose to open the storage box of the vacuum cleaner, and then pull the protruding place by hand, so that the filter paper or dust sponge can be taken out when the cover is taken out, and a layer of dust will be found when it is taken out. At this time, we will tear off a large piece of dust and then clean the sponge carefully.
2. After cleaning, use toilet paper to absorb water, then use a hair dryer to dry it carefully, or you can choose to replace the sponge.
The last step is to pat the filter paper hard on the ground, and then clean up the dust in the filter paper.
