Getting a Central Vac System installed was a good investment and I don't know how I managed without it! No more impurities being blown back into the air, and I don't have to dust as often. I don't have allergies, but it is certainly a bonus for those that do. Now, if only they could come up with a TRULY dust-free clumping litter, I would be ecstatic! Before the central vac I always had an Electrolux, because that is what I grew up with and my Mom swore by that brand.
