The working principle of vacuum cleaner is introduced. The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed, and air is sucked from the suction port, so that the dust box generates a certain degree of vacuum. Dust enters the dust bag in the dust box through the floor brush, suction nozzle, handle, hose and main suction pipe, and the dust remains in the dust bag. The filtered air enters the motor through a filter screen, which is a protective barrier to prevent the dust bag from breaking and the dust from being sucked into the motor. The air entering the motor flows out through the motor, because the carbon brush is constantly worn during the operation of the motor.
