The vacuum cleaner can be divided into vertical, horizontal and portable according to the structure. The working principle of the vacuum cleaner is to use the electric motor to drive the blades to rotate at high speed, generating negative air pressure in the sealed casing to suck the dust debris

The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at high speed, and the air is sucked from the suction port to make the dust box generate a certain vacuum. In the dust bag, the filtered air enters the motor through a layer of filter. This layer of filter is a protective barrier to prevent the dust bag from breaking into the motor and the air entering the motor flows out through the motor. Because it is worn out, another filter is added before it flows out of the vacuum cleaner.

But for users, comfort and cleanliness is the main thing.
