Not sure if you've read my previous posts, I differ with some on here when it comes to rugs, some will tell you to do in your garage, customer house, w/ a tarp, etc. With VLM it won't hurt the rug much nor will it really clean deep down, even though you will see a difference, I'd still look for someone that has taken the time, money, and training and sub the work to them. Not just some dude that does it in his concrete warehouse floor, I'm talking about someone w/ a rug pit. Call around and see who in you're town does it and work something out w/ them. I make 40-60% from pick up/deliver w/ rugs, and I know they're getting done by someone who does rugs for a living, I won't have to worry about damaging/bleeding/sheeding the rug.
That's my take on it.
