Those Royal Procisions/Dirt Devil Platinum Forces were awesome machines, I agree with Rob as I've used them before myself. In my opinion the best upright carpet cleaners that's not a Big Green or a Rug Doctor. I should've bought one from my local vacuum store over a Bissell Proheat 2X from Lowe's. I mean my Bissell was good but not even close. I won't buy a new Bissell again unless if it's a Big Green/Rug Doctor or a Little Green I mentioned earlier.
I also agree with Rob, brushrolls or brushes are not necessary for professional carpet cleaning. I don't know where you found the claim that alot of professionals uses brushes from because most members I found on Mikey's Board or Truck Mount Forums say they don't use them unless in under special circumstances but they'd go to use a Rotovac or a Zipper wand instead that doesn't use a brush. According to them it's not only a waste of time and more labor charge but they also do more damaging to the carpets by shedding fibers out. This is a perfect example of carpet that I can tell didn't get brushed yet the results came out fantastic!
