The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed, and the air is sucked from the suction port to make the dust box generate a certain vacuum.

Vacuum cleaners can be divided into vertical, horizontal and portable according to their structure. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at a high speed to generate negative air pressure in the sealed casing to absorb dust.
