Vacuum Cleaners Discussions

I am looking for thoughts on a canister type carpet cleaner/extractor.. I was thinking to just use a shop-vac and a spray bottle of mixed solution, but I really would like something I can use in my car so I wouldn't have to pay to have it detailed anymore.. As far as needs. I have area rugs and upholstered furniture and a carpet on the bottom half of the walls in my bedroom that I would like to be able to wash... I started looking around because I was thinking of the little green clean machine but was told those are all crap and they all break... I saw Sanitaire SC6070 and liked that but not really liking the price on it (really can't seem to find a consistent one). I saw http://www.amazon.com/Rubbermaid-Commercial-Bissell-9E01-Xtra-Lift/dp/B0000TZYBG <-- that on amazon but can't find any info on it what so ever so I am not sure. I like the price, and if I can use hand tools with it it'd be perfect, but I can't seem to find anything at all...

Any thoughts or recommendations ?
