I've seen this thing but have no idea what it is, sorry my attention has been focused on other things for the past 5 years. Some "Wizard" dude was at one of my section 8 complexes today, recleaned a job we did 2 weeks ago, told the new tenant (she just moved in) he used his special Rotovac "which makes the carpet fluffy" (it was grounded down olefin BTW) & presprayed with a "bacteria killing" prespray. Told the tenant that we cleaned the carpet with only water and the complex should drop me because "that guy in the yellow van doesn't clean carpets the right way, blah, blah". This gullible nimrod goes in and tells the mgr all this, we got a good laugh out of it. My question: Is this thing as good as this dude says it is on olefins? We presprayed, scrubbed with a 175 RPM with bristles and rinsed it looked good after we finished. I need some ammo on this because I've seen this guy advertising on the bulletin board at the local supermarket in my neighboorhood, you know the corkboard where people put lost dogs, cats, car's for sale, etc..... heh...heh....
