jhfc Ron dont you realize that your damn Truckmount will remove soil as well?
I tried to explain that one to him too....
Tried to explain the idea of surfactants in your tlc'er makes the dirt float so you can rinse it out. And solvents break down the stuff that hold the dirt to the carpet. And a vacuum cleaner is to get the large stuff so that you don't make mud.
I think the problem is he can't see what's in his truckmount tank after extraction, and is going by what he can see his vacuum cleaner get out. But if he took the time to evaporate all the water and know how much dirt was extracted with the truckmount he'd understand, may even change his philosophy.
That's why I asked him if he ever did any tests to see how much more soil he would remove doing his method on one side of a room then a rotovac/rx-20 extract on the other side of the room and see what the difference was.
Just because you think the way you're doing something cleans better, doesn't mean it's true. You need test.
