snow wash craze around here!

Currently round my region, I've seen couple of people offering these snow wash type of washing and they are mushrooming. Are they good or are they whack? Found a link in google http://www.yetmachine.com/prod10-Snowash.htm

Personally I don't like to subject my car paint to this high pressure washing.
:dunno

Looks to me that they would have to use strong soap to cut the dirt, that makes me think that its also taking the wax off the car at the same time.
Would be great for RV's or large trucks
