When I arrived at one of my commercial jobs tonight, I was quite surprised to see a "Cintas" box truck out front. They were there to do a tile job I was there for my bi-weekly carpet clean. As I traded info with the two hourly techs found that Cintas had been in the commercial tile cleaning business with the Aerotech for about a year or so. Once again a contract job but they had traveled 85 miles one way to do this relatively small tile job, two techs were there ( I guess) around 2.5 hours 3 hours of drive time, heck I wonder what their charge was, mgr on duty wouldn't disclosed but ask me for a bid. I had given them a tile bid when I first took on the contract and I bet they paid these guys 2-3 times as much as my bid. When the contract is up I will have it next time! I was surprised that the AT was fairly quite but upon looking over the situation they were running 1300 rpms, had the heat set on 135 degrees and 2,000 psi. They also were bypassing the waste tanks and dumping the water on the parking lot right in front of the store's front doors. Techs were nice fellows I ask if they did any residentials he laught and said my house and his! However, they do commercial carpet and hotels.
