The Dirt Devil would be a low end contractor grade unit. I know some central vac guys that really like the MD series. There are many different designs to central vacs as far as the bag or filter or cyclonic. I'm not sure what state you live in but there are some friends in the vacuum world that specialize in this stuff and could offer you service and/ or advice. You'd be surprised how far they are willing to drive for a job too as central vacs are a neat and expanding market niche.
