How A Vacuum Cleaner Works

Have you ever wondered how it is that the vacuum cleaner picks up dust, dirt, debris, lint, crumbs, and maybe even tiny toys, as it goes across your carpet? More than likely, very few people stand there and question exactly how a vacuum cleaner works. We just want the dirt and debris to disappear, right? The method by which your vacuum cleaner helps you clean your home is very specific and, like most appliances, somewhat scientific.

There are several parts to a vacuum that enable it to work effectively. The internal fan is probably them most important part of any vacuum cleaner. This fan is hidden within the vacuum and works by pulling air from outside the vacuum chamber into the bag that holds all of the dirt, etc.

The bag itself is unique from others in that it is designed somewhat like a filter to allow air to pass through its fibers, while trapping small particles such as dust, dirt, lint, and larger particles or pieces of debris, like crumbs and pet hair. Vacuum bags are made either from woven paper or cloth and are disposable once they are full. "Bagless" vacuums have a plastic tray or cup that captures the debris instead of a thick paper bag. The plastic container is then removed, emptied, and then re-used over and over again. It's key to change out your filter on a consistent basis, regardless of the type, so your vacuum cleaner will always work effectively.

The electric motor, intake port, exhaust port, and housing of a vacuum cleaner are also essential to what makes a vacuum cleaner perform its job efficiently. Think of your vacuum cleaner like this: when you drink from a straw, what happens? As you pull the liquid up with your mouth, the suction causes pressure to drop between the bottom and the top of the drinking straw. Simple science says that when pressure is greater at the bottom than the top, the drink is pushed up to your mouth. A vacuum cleaner operates in a similar manner as it picks up the dirt from your carpet.

The electric motor is attached to the internal fan. The fan is designed with angled blades that force air toward the exhaust port, in a forward motion. As the air particles are propelled forward, the air pressure increases in front of the fan and equally decreases behind the fan. Now, just as the pressure at the bottom of your drinking straw drops and creates suction, so does the pressure outside the vacuum cleaner, creating suction inside the cleaner. The air pushes itself through the intake port of the vacuum and that's when you see your carpet debris disappear.

There are upright vacuum cleaners that pull the air into the canister via the head of the vacuum, which meets the floor or carpet. Hand-held vacuum cleaners utilize a flexible hose instead, which has the air intake built-in to the end, or "nose" of the hose. There are tiny wire "fingers" built into the end of that hose and that is where the dirt enters the vacuum bag as it is dislodged from the carpet.

Now that you know how a vacuum cleaner works, it might be more fun to vacuum your carpets...well it was just a thought.
