A central vacuum system (also known as built-in or ducted system) is a type of vacuum system appliance, installed into a building as a semi-permanent fixture. Central vacuum systems are designed to remove dirt and dust from homes and buildings, sending the dirt and dust through PVC pipes installed inside your walls to a collection container (or canister). The central vac canister is typically installed in your garage or basement. Conveniently located inlets that attach to the vacuum hose are installed in walls throughout your home. Strong suction power and central vacuum accessories like motor driven power heads remove the deep down dirt and dust and small debris. Central vac hoses are easy to use and have an on/off control switch located right on the handle.
When buying a central vacuum system, it is very important to match the power unit to the house so that the unit is powerful enough to effectively pull dirt through the system from every nook and cranny on every floor. Buying the right size unit isn’t rocket science, but it can be a little tricky. You must take into consideration the square footage of your house, the length of pipe required to service the system, and the suction necessary.
