The Vacuum Cleaner
By Paul George
2nd March, 2007
Summary
The vacuum cleaner is a household appliance that cleans by suction. It is generally used on a textured surface, such as carpet, and is pushed over the surface, sucking up dust and dirt as it goes. The suction is created by an air pump, a partial vacuum; it creates a difference in pressure between the inside of the machine and the outside air and dirt and dust is taken in to the lower pressure zone. Friction on the carpet causes the dust to be removed from the carpet, or other surface.
