I am shopping for a new auto scrubber. One of the machines Im looking at has this "no chemical" water clean technology. It adds about $1300 to the cost of the scrubber. I would try to explain it but I would just screw it up, so here is the link. http://www.tennantco.com/am-en/equipment/Innovations/Innovations/ec-h2o-nanoclean Is this something that really works? The sales rep said this has been working for over 10 years in their machines and he has demod it hundreds of times with many impressed customers. Im skeptical. Im asking those on here who are smarter than me, is this legit? I clean these floors twice per week(VCT) and they arn't heavily soiled so I don't need really strong chemicals typically. Scott? Mama? SSA? Thanks guys and gals.
