Round Plate Filter Press

There are many different types of vacuum cleaners and carpet cleaning machines but they all work by using the same principal or idea.  A vacuum is created in a tube or system and air is drawn into the system china filter press
through a filter which catches debris and then the air is diffused from the unit out of an exhaust.
The residential upright vacuum cleaner uses the suction principal combined with a spinning brush at the suction opening which is located on the bottom of the vacuum cleaner.  As the brush, which is commonly known as a beater bar, spins at a high rate of speed this beats the carpet and pushes and debris toward the suction opening.  Once the debris has reached the suction opening air forces the debris into a filter bag which catches the debris but lets the air pass through.  Once the air moves passed the filter bag it is expelled through an exhaust vent usually located on the handle box unit of the vacuum cleaner.  Residential vacuums are given this name because they usually have one motor that runs the whole vacuum cleaner.  This motor spins the brush and also operates the suction fan.  Due to increased stress on one motor these types of vacuum cleaners do not have the longevity of a commercial vacuum but are priced relatively low.
Commercial vacuum cleaners work on the same principal as residential vacuum cleaners but are built for abuse and constant operation.  Commercial vacuum cleaner parts are usually readily available and can be replaced by a vacuum cleaner technician.  Most commercial vacuum cleaners utilize two motors, one running the beater brush and the other running the suction fan or fans.  These types of vacuums also utilize that latest technologies by using circuit boards to distribute the power to the vacuums two motors only when needed.  On Membrane Filter Press
