The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, creating negative air pressure in a sealed housing to absorb dust.
The internal structure is divided into power part, speed regulator, filtration system, functional part, protection measures, accessories, etc.
You can take a look at the PTFE-coated filter media in the filtration system.
The dust bag, front filter, and rear filter in the filtration system are divided into different filter materials: paper, cloth, SMS, and HEPA (HEPA high-efficiency filter material).
