The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at high speed, and the air is sucked in from the suction port to produce a certain vacuum in the dust box. The dust enters the filter bag in the dust box through the ground brush, the nozzle, the handle, the hose and the main suction pipe. The dust is left in the filter bag, and the filtered air enters the motor through a filter. To prevent the dust bag from breaking dust inhalation motor a protective barrier, the air into the motor through the motor outflow, due to the motor operation in the continuous wear and tear of the carbon brush, so outflow vacuum cleaner before adding a filter.
The finer the filter material is, the cleaner the air will be, but the worse the air permeability, which affects the air intake motor, reducing the efficiency of the vacuum cleaner. But for users, comfortable and clean is the main thing. Its air permeability is low, so it is all waved to increase the air permeability area. Some of these filter materials can also be cleaned repeatedly. Any filter material has a "lifetime", that is, after long-term use of the filter material has been blocked by small particles of dust. Therefore, paper dust bags are ideal, disposable, hygienic and convenient. After filtering, the fibers will harden, which will affect the filtering effect and breathability. SMS three layer composite filter material is washable, but the air permeability is slightly lower.
