A Beam Central Vacuum System uses tubing installed in the walls of your home to carry dirt, dust and allergens away from living areas to a collection canister in the garage or basement. To activate the system, simply plug in the lightweight 30' hose into the nearest Beam wall inlet. (The average home has three inlets.) Then attach your choice of cleaning tools and you're ready to go. The flexible 30' hose lets you move from room to room for fast, easy whole-house cleaning convenience. It's quiet, too, because the power unit is usually mounted in the garage.
