How Do Central Vacuum Systems Work?

A central vacuum is a three-part system made up of

  1. the power unit where the motor is housed,
  2. the filtration device that holds the canister that collects the vacuumed debris
  3. the interconnection of PVC tunes that are installed in your house walls.

The power unit is a cylinder-like structure that is hanged on the garage or basement wall. The power unit houses the filtration unit and the motor, which creates suctioning power when it spins. This suction power is also known as the water lift and determines the air watts, the real power of the entire vacuuming system.

The first step in setting up the central vacuum system is determining the location of your inlet valves where you will plug the power brush and hose. The best thing about the central vac system is that you can choose convenient locations in your home where you will plug the hose.

You can choose to create as many inlets as possible depending on the size of your home. Professional installers advise that you create a single inlet for a 600 sq ft space in your house. These inlets are linked to an out-of-the way power unit through tubes affixed in your walls. These tubes carry the dirt that you vacuum out of your house and into the receptacle.

When you need to vacuum your house, all you need to do is to plug the retractable hose that links to the power brush to one of the inlets. What makes the power brush unit so convenient is that the ‘on-off’ button is located right on the handle of this lightweight unit so you can control the power button conveniently.

When you start vacuuming, the debris is carried through the hose and into the tubing in the wall and directed toward the power unit where the dirt is filtered and collected in the attached canister. Best of all: one of the advantages of the best central vacs is that you need to empty the canister or dirt bag only 2 times in a year at the most!
