How Vacuum Cleaners Work | Vacuum Cleaners | Finding Best Vacuum Cleaners

Even though it may appear to be a very complicated machine, the conventional vacuum cleaner is actually made up of six essential components: intake port, exhaust port, electric motor, fan, porous bag, and a housing that stores all of the other components.

When you plug the vacuum cleaner into the outlet and turn it on, the following happens:
1. First of all, the electric current will operate the motor, which is attached to the fan, which resembles an airplane propeller.
2. As the blades begin to turn, they will force the air upwards, towards the exhaust port.
3. When the air particles are driven forwards, the density of the particles will increase in front of the fan and therefore decrease behind it.

The pressure drop that occurs behind the fan is similar to the pressure drop when you take a drink through a straw. The pressure level in the area that is behind the fan will drop below the pressure level that is outside of the vacuum cleaner.

This will create a suction inside of the vacuum cleaner. The ambient air will push itself into the vacuum cleaner through the intake port because the air pressure that is inside of the vacuum cleaner is much lower than the pressure on the outside.

Picking the dirt up
The stream of air that the vacuum generates is just like a stream of water. The air particles that move will rub against any loose dust or debris and if it is light enough, the friction will carry the material around the inside of the vacuum cleaner.

As the dirt continues on to the exhaust port, it will pass through the cleaner bag. They tiny holes in the vacuum cleaner bag are large enough to let the air pass through, although too small for the dust particles to fit through. Therefore, when
the air current gets into the bag, the dirt and debris will be collected there.

You can stick the bag anywhere along the path between the intake tube and the exhaust port, just as long as the air current passes through.

Suction
The power of a vacuum cleaner's suction will depend on several factors. The suction can be stronger or weaker depending on:
1. Fan power - In order to generate a strong suction, the motor needs to turn at a good speed.
2. Air passageway - When a lot of debris builds up in the bag, the air will face a greater level of resistance on the way out. Each particle of air will move slowly due to the increase in drag. This is the reason why a vacuum cleaner works much better once you've replaced the bag than when you have been using it for a while.
3. Size of the intake port - With the speed of the vacuum fan being constant, the amount of air that passes through the vacuum cleaner per second is also constant.

The Essential Vacuum Cleaner | Finding Best Vacuum Cleaners

The vacuum cleaner is a truly amazing piece of equipment, as it would be very hard to cope without one. There are many people out there who prefer domestic vacuum cleaners for carpeted floors in their home.

No matter how you look at it, the vacuum cleaner is an ingenious piece of equipment. It has an air pump that creates a partial vacuum to suck up the dust and dirt, which it collects by a filtering system or a cyclone to dispose of later.

Vacuum cleaner types
Based on their configurations, there are many types of vacuum cleans. The following are some of the most known types of vacuum cleaners.

Bagless
Bagless vacuum cleaners, as the name implies, don't use bags. They collect the dust in a compartment which you can quickly and easily empty. This will save you from the headache of dealing with messy and frustrating vacuum bags.

Upright
Upright vacuum cleaners have the pump mounted directly above the suction intake, with the bag mounted on the handle that will normally rise to waist height. The designs of upright vacuum cleaners will normally employ mechanical beaters, which are often rotating brushes, to help dust that has yet to settle be vacuumed up. An attached belt to the vacuum motor will drive these beaters.

Canister types
Canister vacuum cleaners have the motor and the bag in a separate cylinder unit that is connected to the vacuum head by a long flexible hose. Even though the upright units have been tested as being more effective, the lighter and more maneuverable
heads of the canister are also popular. There are some canister models on the market that feature power heads which contain the same type of beaters as found with upright units, even though those types of beaters are driven by a seperate electric
motor.

Backpack
Backpack vacuums are a great tool for commercial type cleaning. Backpack vacuums will allow you to move around rapidly in a large area. It is basically a canister vacuum cleaner, except for the fact that the straps are used to carry the canister
unit on your back.

Central Vacuum
A central or built in vacuum cleaner has the suction motor and bag based in a central location of the building, providing vacuum inlets at strategic places throughout the building. This way, you only need to carry the hose and pickup head from room to room. The hose is normally 25 foot long, allowing a large range of movement without having to change vacuum inlets.

A plastic pipe will connect the vacuum outlets to the central unit. The head of the vacuum may either by un-powered or have beaters that are operated by an air driven or electric motor. The dirt bags in central systems are so big that you only need
to change or empty them once or twice a year.

Robotic
Robot type vacuum cleaners will move around your home, cleaning as they wish. They are compact and powered by batteries.

Hand held
Hand held vacuum cleaners are very small and powered by either batteries or electricity, and very popular with cleaning up small spills.

Wet or dry vacs
Wet or dry vacuum systems can be used to clean up both wet and dry spills and dirt.

Vacuums are very helpful with protecting yourself and your family from dust particles. They are also helpful for those who suffer from allergies that
result from dirt and dust. Before you buy a vacuum cleaner, you should always read some reviews and find out other information to ensure that the vacuum cleaner you buy will meet your needs.The vacuum cleaner is a truly amazing piece of equipment, as it would be very hard to cope without one[...]
