How Do Vacuum Cleaners Work?

Vacuum cleaners! Where would we be without them, one of the many handy inventions of the 21st century! Many people ask themselves how do vacuum cleaners work. Mostly every household has them and makes their lives so much easier, a simple device that has sucked up dust and small particles instead of resorting to wiping it down by hand. These guys have saved us hours of time and we take them for granted, but we are always grateful for their service! But how do vacuum cleaners work?

While discussing how it works we have to know what makes a vacuum. Vacuums usually come with a cord built-in or cordless. A vacuum usually contains all of the same features but may look differently varying from machine to machine. All vacuum cleaners tend to have an intake port. The intake port sucks up all the stuff through it. The intake port can vary from having brushes or not having them, the reason for the brushes to kick up any dust that is around in carpeted surfaces.

An exhaust port, all vacuums have this to blow air out from the vacuum to continue functioning smoothly. The electric motor is where the negative pressure is created with the use of the fan and its blades. The filter is what all the stuff that has been collected has to pass through before ending up in the canister or bag, this is to collect any small dust particles.

The Usage of Negative Pressure

An example of how a vacuum uses negative pressure is like sucking through a straw. When sucking through a straw you create negative air pressure in the straw. Negative pressure is the pressure that is lower than the surrounding area, which causes the flow of liquid to your mouth and in the case of a vacuum cleaner the flow of air and dust. Every single vacuum uses this as a method to clean carpeted and hardwood surfaces.

The motor of every vacuum is what creates negative pressure that causes the suction. The motor has fan blades that force air through. This suction process collects all the dust and other particles that it happens to collect and shoots it out into the canister or bag which collects it all up. To continue this process the vacuum has an exhaust port so that it can continue to suck an unlimited amount of air without it having to stop because it is full. 

The Filter’s Use

Every vacuum bag has a filter, but why? The filter is located between suction and ejection of dust and dirt. If there wasn’t a filter in place it would be very harmful every time we used a vacuum cleaner to clean around the house. The reason behind this is because every time we clean up we pick up particles that are not able to be seen by the naked eye. These particles if built up in our lungs over time can cause very dangerous health problems.

Due to the fact, not all these particles are collected in our container it has to go through at least one filter. This will remove all the particles and now the air is safe once again. Do not forget to clean out your filter from time to time if you don’t the places you cleaned will smell worse.

To discuss more in-depth about attachments for the intake port. As you browse through vacuums you begin to notice several attachments. As stated earlier about a brushed intake port attachment is to kick up dust by causing friction. Another commonly seen intake port attachment is a small one. The reason behind this is because a smaller intake port has the ability to suck with a greater force than one of a larger capacity. This is because the air is able to move faster in a confined area. Those are the two main attachments you see or variations of both combined.

Now learning how do vacuum cleaners work, you get a newfound appreciation for them. Vacuum is one of the best modern inventions that only seem to improve over time. All vacuums seem to operate the same way as I just said, a simple but very helpful device. Without them in our lives, our homes and lives would be much dirtier places, so it is good to be thankful for them.
