Hard to rate them as the carpet came up clean and looked fantastic. Actually better than the previous people we have used...but a stain showed through later which I got of very easy and the biggest problem was the spray that was put on the carpet before cleaning was also over the lounge and over furniture..everywhere. So I had cleaning up to do after. Not careful enough with his spraying. Pity seeing the machine he has does a great job. It is not run from a van but the whole machine comes inside and he puts water into it.
