How A Vacuum Cleaner Works

How A Vacuum Cleaner Works

As you can read in our article on the different types of vacuum cleaners here: you know there are several types of vacuum cleaners. However, they all function using the same principles.

A vacuum contains a motor, and when the machine is turned on, the motor drives a fan which then lowers the air pressure inside. This is when a partial vacuum is created, so the ambient air pressure outside the vacuum forces the air through the hose and into the appliance.

Once inside the machine, the dust and dirt can be filtered out in a couple of different ways, and this obviously all depends on the type of vacuum you have. For bagged vacuums, the air is able to enter the bag, then pass through the porous material, leaving the dirt trapped in the bag.

Other vacuums using a canister will spin the air round at a very high speed, throwing out the dirt, which then drops down the sides to collect at the bottom.

Who Invented The Vacuum Cleaner?

Over 100 years ago, janitor Murray Spangler's health was deteriating, with the dust from manually sweeping every day causing him asthma problems. This is how the "suction sweeper" - as he called it - was born, along with the beginning of the well-known company Hoover. The Hoover vacuum cleaner was so popular that we now, to this date, still refer to our vacuums as hoovers, even when we own any brand of vacuum.

A more industrial style of vacuum is the wet and dry machines. Here, the dirt is suspended in water particles. Due to being heaving than air particles, the water comes up into the vacuum then drops down into a resevoir.

Obviously, the motor of the vacuum seems to be the most crucial part to a vacuum's suction strength, but don't assume that this means it is broken if your machine has lost suction - the most common problem that occurs with a vacuum.
