Vacuums and How It Goes Down

There are a few other factors that come into play and we will take a look at those and see how it all goes down inside your vacuum.
The modern day vacuum is made up of an electric motor, an intake, an exhaust, a fan, a bag, the rotating brush, and the housing that encases it all inside.
Some that you will find are bag less but for this discussion we will keep to a bagged model.
Upon plugging in the vacuum the motor starts up spinning a fan which closely resembles a propeller.
As the fan turns it will begin to force air towards the exhaust.
This in turn increases air pressure in front of the fan and decreases it behind it.
Once this happens it creates a suction that allows the vacuum to suck in outside air into the vacuum.
So you know have air moving from the intake to the exhaust of the vacuum.
The friction caused by the air allows it to pick up any debris small enough for it to lift.
This is also the reason for the rotating brushes, it allows the dirt to be kicked up and sucked into the vacuum.
The bag is situated in between the intake and the exhaust allowing it to collect the debris particles while still allowing air to pass through.
The bag is just like an air filter in your home air conditioning.
It uses the same principle.
This is why sometimes your vacuum may act a bit sluggish.
This is do to the bag being to full and not allowing air to flow through the vacuum properly.
You will find other vacuums as well ranging from a canister one to a cyclone.
All working off the same principles, just with slightly different variations.
