I checked out the site you referred to and they have some very nice equipment. Normally I don't recommend at-home cleaning machines because they usually don't get the water hot enough, and they often spray, and leave a lot of water in the carpet which can create mold, etc.
That said, the equipment on the site you referred to is a lot more advance that your usual Bissell or other at home machines. I wouldn't really be that suprised if professional carpet cleaners that don't have van mounted equipment would use one of the diamer carpet cleaners to do the job.
Thanks again for your post and we look forward to having you as a part of our community here on the FindAnyFloor.com forums.
