How does a vacuum cleaner work and how is it able to suck like that?
In: Engineering
Basically it’s like a ventilator just turned around. A ventilator blows air in a specific direction while taking in air from any direction. If you put a pipe or a tunnel at the entry of a ventilator the air will get sucked into the tunnel. If you then form the tunnel in a way where it get smaller at one end th air gets sucked even stronger.
This is basically what vacuum cleaners do. They have a turned around ventilator inside and some filters.
