Another benefit of the central vacuum is, because of the remote location of the motor unit, there is much less noise in the room being cleaned than with a standard vacuum cleaner. A well-designed cyclonic filtration system loses suction power due to airflow restriction only when the collection vessel is almost full. The most common upright vacuum cleaners use a drive-belt powered by the suction motor to rotate the brush-roll. Atmospheric pressure then pushes the air through the carpet and into the nozzle, and so the dust is literally pushed into the bag.
