"The biggest trucks make a huge difference".
Sounds like a little/short guy with a small penis complex that makes up for it with his
big truck.
"Dry steam". Holy oxymoron.
Anyone with an ounce of sense would see through this statement.
First, not all of us compensate for our, er, shortfalls with big trucks. It is much cheaper to simply lie about how long five inches are...
Secondly, to me, "dry steam" refers to 5% or less water to volume of super-heated steam or "vapor."
I've used it to clean one or two carpets, but I don't think it is very beneficial due to the risk of heat induced changes to synthetic and natural fibers. Reading his website, I think he is simply coining a phrase and doing HWE.
Not knocking that, but as high temperature vapor cleaning becomes more widely used and understood by the public, they'll expect an entirely different process than he describes.
BTW, using vapor really works to clean and freshen rugs and carpet, but you have to be careful. Very careful!
