Vacuum cleaners work by having powered rotating brushes which loosen up dirt and dust on a carpet. The cleaner also has a strong fan which then sucks the loosened particles up into the into a special multi-layer filter bag. In HEPA vacuum cleaners, the air is then passed through a HERPA filter before entering the air in the room again. To get a carpet really clean, need to pass the suction head over an area eight times.
