i used the rug doctor on my cream carpter, as i have 16mth old child, he likes to paint the carpet with food..lol
came up really well
only issue we had was it made it quite damp and smelt damp for a bout 7days, other than that it was ok
he put the heating on after a day or so to help dry it, much better then
maybe we went over the same area a few times, to much, but otherwise very good
