I'm am so obsessed with my Hoover SteamVac. It is by far, one of the best household purchases I've made...ever
I use it at least twice a month to either rid my office area rug of marks from foot traffic or use it clean cat vomit from various rugs around my house (of course they can't just puke on the hardwood floors). It cost under $150 -- a steal of a deal. I don't have any wall-to-wall carpets in my house and I STILL think it was a great buy; I can't imagine how amazing I would think it is if I got to clean an entire room of carpeting with it. I also recommend the Hoover cleaning solution, it is the best around.
