Opinions on carpet steam cleaners: which one's the best?

i have a bissle pro heat 2x it works pretty good gets most of the water out, during the colder months if were are going to be walking around the clean area i put towels down (not to soak up water but to keep the kids from getting it dirty again before it drys) when it is hot (80's +) takes maybe an hour to dry i don't regret the purchase and find only thing i don't like if the tank the clean water goes into a bladder and has a seperate tank for the solution that as it is sprayed they mix (this is fine with me) but then the dirty water fills the container around the bladder so to dump the dirty water you have to dump lift the entire tank (if it a smal spot then you are lifting clean and dirty water and only dumping the dirty) this is a bit of a hassle since i do mostly spot cleaning, even though the clean water doesn't dump out with the dirty water still don't like having to carry that weight each time i dump dirty water when i did not use all the clean water (just heavy) but i acctually do like no mixing the water with the solution i like having them seperate, becaue there is a dial to adujst the cleaning setting light clean normal and heavy traffic and clean rinse (the clean rinse will not work if the solution tank is empty it still puts some solution on the water but not a lot (bissel brand solution has scotch guard in it this may be why) but i am overal happy with the machine it cleans well does not over wet gets a good amount of the water out the hose is maliuable and not hard have used it on a matress in the late afternoon (during summer) and the bed was ready that night (it was in the low to mid 80's that day) would buy another one despite the way the the clean and dirty water is done (they do not mix but it is a bit of annoying but not problemsome) hard to explain...very satisfied with my machine......do recomend it can't say what percentage of water is sucked back up but it is most of it
