what...? that's like every other carpet cleaner out there..
One time I actually grabbed a guy's stainless steel wand from his van and asked him where his jets are?? You could not see the jets from all the lint and hair built up around it!!
I told him he should be ashamed to "clean" with a tool like that and proceeded to clean it with high pressure from my truckmount, followed with Viper Restore acid to make it shiny. Cleaned it up in less then 10 minutes....
