My dad really loves the Dyson vacuum. He loves the vacuum so much that when I bought a vacuum a year and a half ago he got mad that I bought a Bissell vacuum. The Dyson is around $300 and the Bissell was a modest $80. Who could blame me and for that matter who could blame him? It's got a ball for a wheel that helps it "turn on dime" and the a container looks like the Mr. Fusion from Back to the Future II
Really, the Dyson looks like like it was built by guy in his garage but it somehow works better than any piece of crap that you or I could purchase at a Bed, Bath & Beyond.
