I had stains from Cats bringing up hairballs, plus black smuges from a pair of shoes I wore, potato chip grease and last Xmas party 2009 food stains. I also had a few scatter rugs that were very stained from last xmas - 11 months ago!! and all came out like brand new. I had a rug piece I compared it to and it was yes!! like the day I purchased it. Only a wand and a hose came in. The water went through the rug with cleaning solution and then rinsed, and the excess water was extracted and sent to a waste tank on their truck I was so pleased. The fiber were not frayed from being brushed and no excess chemicals were left in my rug. They were so affordable. they were better than that Stanley guy because they did the same thing but were $90 cheaper that the other guy's quote. They are definitely on my phone list.
