What is the purpose of hotel training employees to use vacuum cleaners?

Throw the dust into the dust cup and the air will be exhausted.

The working principle of vacuum cleaner is that the motor drives the blades to rotate at high speed, which generates negative pressure in the sealed shell and sucks dust. Generally, vacuum cleaners are popular now, and the dust is centrifugally thrown into the dust cup in the motor, and the air is exhausted. Vacuum cleaners are divided into household vacuum cleaners and industrial vacuum cleaners. Household vacuum cleaners are divided into hand-held, vertical and horizontal. Now horizontal vacuum cleaners are gradually eliminated, and hand-held and vertical vacuum cleaners occupy a large market share.
