For starters, BEAM dealers have been educating customers that almost any home can be retrofitted for a central vacuum system without damaging or replacing sections of interior walls. As long as tubing can be routed horizontally between joists and vertically through an interior wall, utility chase or cold air return, the home can be equipped with a central vacuum system. The only openings required in walls are no larger than an inlet valve.
A third factor is that many consumers want the added cleaning convenience a central vacuum system delivers. It's much easier to clean stairs with a hose that covers the entire staircase than trying to balance a portable vacuum on a stair tread, or to extend the central vacuum wand to reach ceiling corners, fans and vents.
