How Vacuum Cleaners Work

Real Estate Agent with Kims Properties

You use the easiest suction mechanism when you sip soda through a straw, as it drops pressure between the top of the straw and the bottom of the straw. The soda gets pushed into the straw due to the higher pressure of the fluid on the bottom than its top. A vacuum cleaner basically works similarly. In this article, we will explain more how vacuum cleaners work, and the technology involved with how they clean.

Design of a Standard Vacuum Cleaner
The design of a standard vacuum cleaner is very easy to understand, but while cleaning it depends on a number of physical rules. A traditional vacuum cleaner may look like a very complex machine, but it mainly includes six components only, including:
- One intake port that may also include cleaning accessories of various types
- One exhaust port to exhaust the air sucked by the fan
- A fan to create a vacuum in the intake hose
- An electric motor to operate the machine
- A housing containing all the components
- A porous bag to collect dust and debris

How Vacuum Cleaners Work - Removing Dirt and Debris
When the vacuum cleaner is turned on by plugging in it into a wall socket then it starts working as under:
Its motor starts working with the help of the electric current passing through it. This motor is attached to its fan with angled blades to work like the propeller in an airplane. When the blades of the fan start turning, they propel the air towards the exhaust port of the vacuum cleaner. The density of air particles increases in front of the fan when they are driven forward. However, behind the fan, the density of air particles decreases.

The drop in pressure behind the fan resembles with the drop of pressure in your straw when you sip your drink through it. The level of pressure behind the fan becomes lower than the level of pressure outside the machine due to the pressure of environmental air. This drop in internal pressure creates a partial vacuum to suck things inside the vacuum cleaner as the air outside the vacuum cleaner pushes itself into the machine through its intake port.

The passage inside the vacuum cleaner remains open as long as its fan is running as it will allow a constant stream of air to move through its intake port to go out from its exhaust port. This stream of air flowing through your vacuum cleaner works on the principle of friction to collect the debris and dirt from your carpet. The particles of moving air rub against any loose particles of debris and dust while moving in. If the suction of the fan is stronger than the weight of debris particles then they are carried into the vacuum cleaner due to friction.

In Conclusion
When it comes to learning how vacuum cleaners work, knowing the technology involved and the parts it’s made of makes it easier to understand. The power a vacuum uses to run starts a fan to create airflow in the vacuum. Basically, they work by creating a vacuum inside, that changes the air pressure in order to suck dirt and bacteria out of your flooring.
