How does a vacuum cleaner work? - R
A Vacuum Cleaner Works
Vacuum Cleaners are a type of simple machine that are useful for cleaning and making your house beautiful and clean; it even says it in the word! The vacuum cleaner was invented during the 1800’s and was first called the “sweeping machine”. The vacuum cleaner has nine important parts. They are the intake and the outtake ports, the dust bag, a filter, an electric motor, a fan, the vacuum chamber, a rotating brush, and a filter.
How a vacuum cleaner works:
Figure 1: Here is a picture of a vaccum cleaner.
Have you ever wondered why a vacuum cleaner works so well? It’s all because air is trying to get into the vacuum chamber. As the air rushes into the vacuum chamber through the intake port it takes dirt with it. The dirt is contained in the dust bag which can be taken out to be emptied. The dust bag contains micro filters that are helpful for trapping the little tiny pieces of dirt. The air leaves the vacuum cleaner through the outtake port, leaving the dirt to rest in the vacuum chamber inside the dust bag. Vacuum cleaners also have many different speeds. The different speeds help the vacuum cleaner suck up more air and dirt depending on the suction needed for the type of surface.
How each part of the vacuum cleaner is important:
Every piece of the vacuum cleaner helps in some way. Did you know that the vacuum cleaner does not contain any air when you turn it on? The true definition for a vacuum is a space with no air. This is why that the outtake port also known as the exhaust port comes in handy. The outtake port (exhaust port) makes sure that there is no excess air that is in the vacuum chamber. The intake port is where the dirt and the air enters the vacuum cleaner. The dust bag is used to keep
all of the dirt in. The dust bag is disposable and can be replaced. The motor helps power the whole vacuum cleaner. The motor, which is inside the vacuum cleaner, is normally electric. The vacuum chamber is where the dust bag rests, which contains all of the dirt. The fan helps to collect the dirt using pressure. The rotating brush is there to stir up the dirt and makes it easier for the dirt to find its way into to the dust bag. The filter is very important because it helps to keep the tiny particles of dirt away from the motor, which helps maintain the machine in good working order.

Who invented the first vacuum cleaner:
The first vacuum cleaner was not actually called the vacuum cleaner. It was called the sweeping machine. The sweeping machine was invented by Ives McGaffey. The sweeping machine was invented in was invented in the late 1800’s.
Vacuum cleaner attachments:
The vaccum cleaner has many other parts not just the ones inside of it. The vaccum cleaner has attachments like the suction tube, the electrical cord, suction nozzles, and extention tubes. Some vacuum cleaners also have meters that let you know the amount of dirt that is underneath the intake port. Some vacuums also come with charging stations
Vacuum cleaners are like straws. How?
Vacuum cleaner and straws have a lot in common, just by the way they work. The way you use a straw is by sucking on the opening when the other opening is in liquid. As you suck on the opening of the straw (the one that is not in the liquid) air is consistly trying to get into the tube of the straw pushing the luqid with it. It is like what happens when the air tries to get into the inside of the vacuum and sucks up dirt with it.

this attaches to the handle and can be used to get hard to reach places.
- these nozzles attach to the suction tube and are used as the intake port when using the suction tube.
