In households these days, this appliance is essential. Thanks to vacuum cleaners, your working and living spaces become spotlessly clean. Your chores get more comfortable and time-saving, as well. How can it be that effective? Let’s have a look at the working principle of a vacuum cleaner.
Suction power
How this cleaning device is capable of sucking up debris is similar to how you sip your drink through a straw. The sucking action produces a negative pressure of the air inside the straw. This pressure is not as high as that of the surrounding atmosphere. Like in some space films, the way that a spaceship hull’s breach can suck humans into space, vacuums generate negative pressure inside, causing an airflow into it.
Power motor
A Best vacuum cleaner for home relies on an electric motor which spins the fan, sucks in and pushes out the air to the other side, into the canister or the bag, for negative pressure creation. You may think that it would not function after a couple of seconds because it is only possible to force a lot of air into the confined space. To deal with this, the device comes with an exhaust port venting out the air to the other side, hence letting the motor keep working as usual.
Filter
Still, the air does not simply go through and be removed on the other side. That way, it would harm those using the cleaner. Ever wonder why? On top of the grime and dirt that the machine collects, it also picks up fine particles which are nearly invisible to your eye. If you inhale them in a large enough quantity, they are likely to hurt your lungs.
Since the canister does not entirely trap the particles, the vacuum passes the air through one fine filter or more. It is usually a HEPA filter (high-efficiency particulate air) that helps eliminate just about any type of dust. That is when your breathing air becomes fresh again.
Attachments
The power of vacuums has to do with not only with the motor power but also the intake port’s size. This part works to suck up the dust and dirt. If the intake is small, there will be more suction power created, since squeezing the same volume of air through the narrow passage is equal to faster-moving air. That is why the attachments whose entry ports are smaller tend to have a higher suction than a bigger ones.
The bottom line
Though there are various types of 
best rated vacuum cleaners, all of them function on the principle of generating negative pressure by using a fan, sucking up and trapping the dirt, handling the exhaust air before releasing it. Your house is probably a dirtier place to live in without them.
