We bought this for cleaning a couple of couches, which didn't seem out of the ordinary. It seems to work well - a noticeable difference and an encouraging bucket of dirty water. It would have been great - and easier - if the instruction book had more to it, or if the Bissell site had tips-and-tricks, possibly from other users. A fair bit of trial and error on our end. The unit is robust and works well though - I would definitely recommend it.
