A good vacuum cleaner should be able to suck out cleanly while also rechargeable handheld vacuum cleanerpreventing secondary pollution. You can see the use of ordinary filter cotton of a dog and a Philips vacuum cleaner, there will be dust flying out during the work process, visible sealing is not ideal. This dust pollution is no less harmful than haze.

The vacuum cleaner's operating principle.

The vacuum cleaner is made up of three major components: dust starting, dust absorbing, and dust filtering, which typically include a series-excited rectifier motor, centrifugal fan, filter (bag), and dust absorbing accessories. It is classified into three types based on the filtration method: dust bag vacuum cleaners, water filter vacuum cleaners, and cyclone filter vacuum cleaners.

Because it has an electric extractor fan in its "head," a vacuum cleaner can remove dust.

Under the action of suction and pressure, the air is discharged at high speed, while the air in the front part of the fan constantly replenishes the air in the fan, resulting in an instantaneous vacuum inside the vacuum cleaner and a negative Zimmermann Kids HKpressure difference with the outside atmosphere, through which the dust-containing air is inhaled.

What can't a vacuum cleaner pick up?

Particles that are harmful to human lungs range in size from 0.1 to 10 microns, with the most dangerous being less than 5 microns. The harm caused by fine particulate matter can be acute or cumulative, resulting in chronic poisoning over time. This type of basic is also impossible for the vacuum cleaner to suck away, or the vacuum cleaner will dry the air purifier work.

The greater the suction power, the less effective the cleaning! The suction power of Jimmy Wongthe vacuum cleaner is sometimes too strong, but it cannot complete the cleaning. To be effective, there must be a small gap between the vacuum cleaner and the object to be cleaned; otherwise, the surface of the object will obstruct the suction head, preventing the vacuum cleaner from sucking out the dust.
