ELECTRIC MOTOR
Vacuum cleaners use an electric motor that spins a fan that sucks in the air – and any small particles trapped in it – and pushes it out the other side, into a bag or box, to create negative pressure. Then you might think that; after a few seconds, it will stop working because you can only push a limited amount of air into a confined space. To solve this problem, the vacuum cleaner has an air outlet port on the other side, allowing the motor to continue to operate normally.

FILTER
The filter lets air just pass through and get pushed out to the other side. It will be very harmful to people whose vacuum cleaners. Why? Well, in addition, the dirt that a vacuum cleaner picks up,It can also pick up very small particles that are invisible to the naked eye. If inhaled in sufficient quantities, they can damage the lungs. Since not all of these particles are captured by the bag or box, a vacuum cleaner will pass the air through at least a fine filter and usually a HEPA filter to remove nearly all of the dust. Only now can the air be safely-breathed.

These are some attachments and how they work.

Upholstery tool: This tool is usually 4-6 inches’ wide. It’s basically a mini vacuum just for stairs, mattresses and things like that.
