1. The basic principle of vacuuming. The centrifugal impeller of the vehicle-mounted vacuum cleaner is quickly driven by the motor to quickly discharge the gas in the centrifugal impeller to the centrifugal fan, and at the same time, the gas in the vacuum is continuously filled into the centrifugal fan. In that way, a higher pressure difference is generated with the outside. The floating dust and dirt from the suction nozzle are sucked in with the gas to vacuum a part, and filtered through the filter device to collect the floating dust and dirt in the dust tube.

2. The original of the vacuum cleaner. The adsorption force vacuum cleaner will continue to be equipped with a series of cleaners and suction nozzles to facilitate cleaning the gaps in the corners:
(1) Throat: All adsorption-type vacuum cleaners are equipped with hard throats, which are used to connect soft throats and accessories for cleaning.
(2) Electric brush: The cleaning head of a vehicle-mounted vacuum cleaner is a special part of a hybrid vacuum cleaner.
(3) Round brush head: The suction nozzle is also small and can rotate 360 ​​degrees.
(4) Flat nozzle: also known as the gap nozzle, it is a long, thin, flat and hard nozzle. Especially suitable for cleaning corners, radiant heaters, corners and shallow narrow areas.
(5) Dust sweeping brush: made of long and soft soft hair, suitable for cleaning curtain cloth, walls, etc.
