Even though it may appear to be a very complicated machine, the conventional vacuum cleaner is actually made up of six essential components: intake port, exhaust port, electric motor, fan, porous bag, and a housing that stores all of the other components.
When you plug the vacuum cleaner into the outlet and turn it on, the following happens:
1. First of all, the electric current will operate the motor, which is attached to the fan, which resembles an airplane propeller.
2. As the blades begin to turn, they will force the air upwards, towards the exhaust port.
3. When the air particles are driven forwards, the density of the particles will increase in front of the fan and therefore decrease behind it.
The pressure drop that occurs behind the fan is similar to the pressure drop when you take a drink through a straw. The pressure level in the area that is behind the fan will drop below the pressure level that is outside of the vacuum cleaner.
This will create a suction inside of the vacuum cleaner. The ambient air will push itself into the vacuum cleaner through the intake port because the air pressure that is inside of the vacuum...
