Is a good pic. As a cleaner I get the idea, i know the history and process behind, but as a client maybe get confusing how all that dirt would be on the rug, Like emptying your waste tank on a rug and showing it. Some may get offended. On the other hand it shows what really is on and in the carpet. I think can be a double side knife.
or better yet one house that was moderately clean and this is what I got out. 13 pounds dirt. they used chemDry for years ha ha haHA View attachment 4839
Did anyone read the recent trade mag article of Saddam Husseins rug that someone had bought and had cleaned, it showed a pic similar to Robs of the pile of loose dirt on the rug.
