I totally agree, Daniel.
I used it in a health club a few weeks back, and was impressed. But truth be told, it wasn't the dirtiest place around, so I wanted to reserve any judgment until I came across a true filthy dump.
Well, that dump came this past weekend.............my living room!!!
I didn't take any pics, but the carpet in my living room is identical to the stuff in your pics, and the condition was similar. Mine is a cut pile nylon from shaw, the color is called "Koi Pond", looks just like the stuff in your pics.
Anyway, I mixed mine by eyeball, put some #1, #2, and some of the booster in the mytee inline, and have at it. Gave it a good scrubbing with the 175 and red pad, dwell about 20 mins or so, then rinsed at 450 psi. My usual sauce of choice is the Pro's Choice Ultra TLC, but can't stand the way that stuff foams up. I didn't get that with the orangeforce. It cut through the crap just as easily, didn't foam no where near as badly, and leaves a much better fragrance in the house. Too bad I'm already stocked up on chems, cause I'd gladly switch to the orangeforce, and plan to when I need to restock.
