Vacuflo built-in central vacuum system has been showing to me as the best system.  Does anyone have experience?  How would you rate various systems?  Thanks for anyones's advice.

Thanks Greg.  Yes I visited a dealer who cared Beam, Nutone, Vacuflo, and I think one other.  He gave Vacuflo high marks.  We have built two previous new homes and are relocating again, and of course, builting new again.  We have had Fasco and Nutone, and liked the fact of central vacuum systems.  Only draw back we had previously was the weight of the hose, plus length, and the fact we had to plug in the power head separately.  With the uprights coming out with the "windtunnel" concept, I thought Vacuflo may be a better system.  I am not impressed with the carpet beater, but it has a different concept with spaced brushes.  Looks can be decieving.  
 
It looks like this web forum is mainly dealers, who will have personnal benefits on selling what they carry.  Was hoping I could get some good feedback on all the various brands.  I am not too concerned with filtration, since the unit will exhaust outside the house and garage, so not sure a bag is critical.  I appreicate your comments on the capacity.  Anyother comments are still welcome.  We are about 30 days from needed to give the go ahead and the make.
