As most people do today, I looked for on-line reviews before use. The reviews rated this carpet cleaner as the one to use for best results and you know (tongue in cheek) that you "can't go wrong" using those reviews. (Hahaha !!) But seriously, in this case "THEY" were right. It worked just as the reviews said and it will be the carpet cleaner for me. I know that Bissell haas other cleaners, I didn't try them and probably won't now that I found and tried this one. So thank you on-line reviewers for this one.
