SO VERY cool - https://www.youtube.com/watch?v=0qo-ZXw2k-4&list=UUofLIkht-Y37LByIKGHMVGQ I used to fix high end vacuums as a side hobby, and own a Dyson DC 33. I must say, my Dyson is one of the best vacuums I have ever owned. Their customer support is also outstanding (just got done dealing with their CS, above and beyond what I expected). Miele, SEBO, Riccar/Simplicity, and Electrolux are other, outstanding options as well. All these, including Dyson, are really the ONLY options you would want to consider when buying a serious vacuum.
