The Central Vacuum System (CVS) is composed of several components including a cleaner host, pipe network, vacuum port, and vacuum accessories. The main vacuum cleaner unit is typically installed in the garage, balcony, or equipment room. To use the system, you would connect a hose to the vacuum suction port located in different areas of your home. The suction power generated by the main unit will then pull in harmful gases, dust, and other debris through the vacuum cleaning pipes.
