Vacuum Cleaners

Vacuum cleaners are a common household appliance used for cleaning most surfaces. On the outside they comprise of a rectangular or oval body with a piece of flexible hose at one end connected to a snout used for sucking up dust. Inside the main body of a vacuum cleaner is a fan attached to a powerful motor. When switched on, this fan begins to suck in air through the hose. As the snout at the end of the flexible hose is pointed at a surface, the particles of dust on that surface are sucked into a porous dust bag. Since it is porous, this bag allows the air to escape out, from the other side of the vacuum cleaner, but it retains the dust within it. Once full this bag is emptied. In case the bag is not emptied or replaced at regular intervals, the suction power of the vacuum cleaner tends to diminish.
