I have used Rug Doctor quite a bit. The only problem I have with them is the 24 hour thing. I don't like being on a time limit. Also, the last time I rented one as I was turning it in a lady came back with hers & explained that her carpet had just been ruined. Whoever used it ahead of her had run bleach through it & as she started to use it her carpet got bleached. I don't know how that happened, I guess it wasn't completely empty or something. You'd think she would have been able to smell it.
Charles, the one I bought is a Bissell Powersteamer Powerbrush. It was around $90 at Walmart. It has gotten some pretty good reviews. It doesn't heat the water but my tap water gets pretty hot. I also have a cannister one but it attatches to the kitchen sink, my house is too big for it but I l loved the fact that I didn't have to fill it or empty it quite as often. It also wasn't that powerful.
There's a fine line between genius and insanity. I have erased this line.
