How Does a Vacuum Cleaner Really Work?

Inside the Vacuum Cleaner

Once you drink soda via a straw, you might bein between the bottom of the straw and also the leading of the straw.

With greater fluid pressure in the bottom than the top, then soda is pressed up to your mouth. ­
This is exactly the same fundamental mechanism at perform in a vacuum cleaner, although the execution can be a bit much more difficult.


In this article, we’ll appear inside a vacuum cleaner and discover how and why it puts suction to work whenever cleaning up the dust and debris inside your house.


As we’ll see, the regular vac design is quite straightforward, however it relies on physical principles in cleaning successfully.


If you plug the vacuum cleaner in and turn it on, this really is what takes place:


The electric power runs the motor. The motor is attached to the fan, which uses angled blades (like an airplane propeller).
As the fan blades turn, they force air forward, toward the exhaust port (check out How Airplanes Operate to discover what causes this).
When air particulates are driven forward, density of particles (and consequently the air pressure) increases in front of the fan then decreases behind the fan.


It might look like a complex machine, but the conventional vacuum cleaner is actually produced up of only six vital components:
An intake port, which could include many different cleaning accessories

• Exhaust port
• Electric motor
• Fan
• Bag
• Housing that includes all of the other specifics
• Filters

This pressure lowering behind the fan is like a pressure drop within the straw if you sip from your drink. The pressure level inside the area behind the vac fan drops under the pressure amount outside the vacuum cleaner (the ambient air pressure).


This then will create suction, a partial vacuum, inside the vacuum cleaner. Then an ambient air pushes itself into the vac through the intake port due to the fact that the air pressure within the vac cleaner is lesser compared to the pressure outside.


As long as the fan is running along with the passageway by way of the vac cleaner keeps open, there is a continuous stream of air moving through the intake port and out the exhaust port.
