The funny thing is I am pretty sure there are many out there cleaning carpet everyday with 1.5 hose, portys in the back of a van or truck.....ETM. They are possibly working everyday and making money, even maybe doing it this way for years. I don't mean to sound coo-coo but I do think we can get overboard on how technical this job is.
I am not saying we are not doing a better job, and I do think that on high end furniture, stone, and even some carpet, you better know what the hell you are doing, but for the average joe carpet, massive TM's, 2.5, 4 2 door, hsk, 18 flow, all these things are kinda just for our own gadget warped minds and we just can't help ourselves.
I remember when I first started I had chems coming out of every window of my van, I have done about every hose set up possible even went as far as running 4 2 wand....yeah Y stuck right on the end of my PC Quad. Even built the VW TM.....I AM A JUNKIE, but it has also helped me in understanding some things.
This goes back to my days when Joe B and I were on better terms.....This is how I got my Nickname "Lumberjack". You need to understand I had just come from owning a Drywall Constuction Co.... Carpet cleaning was childs play to me back then.
