The handheld vacuum is small in size and very convenient to carry and use. It is a household cleaning product between ordinary household vacuum cleaners and portable vacuum cleaners. It is more suitable for cleaning small spaces. It is mainly used for cleaning inside the car, and it also has a good effect on keyboards and electrical appliances. The disadvantage is that the power is small and the suction is not strong enough.

The handheld vacuum can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate suction and pressure at a speed of 500 cycles per second. The air in the vacuum cleaner creates an instant vacuum inside the vacuum cleaner, which forms a negative pressure with the external atmospheric pressure. Brushes, long pipes, elbows, hoses, and hose joints enter the dust filter bag, and dust and other debris remain in the dust filter bag, and the air is purified by the filter. Then, it is discharged from the tail of the body. The handheld vacuum can be equipped with different parts to complete different cleaning tasks, such as a floor brush to clean the floor, a flat brush to clean sofa surfaces, sheets, curtains, etc., and a small suction nozzle to remove dust in small corners and dirt in some household appliances.
Application fields of handheld vacuum: carpet, car cleaning, electrical appliances, home furnishing, etc.
