Sebo is the best vacuum system I have ever had. Once you get one, it lasts 4ever. I have two posts and an older guy that you drag, but I love them both. I had a Sebo central vacuum in my previous apartment. Nothing beats picking up dirt and really deep cleaning. Powerheads are self-propelled and really pull through. I go through 2 fan brushes a year and they really clean the carpet. Hospital HEPA filters trap dust, and for the money you can't get much better.
