I could swallow this better if they hadn't said "your machine did not make a rating at all". Well allrighty then.I can only say, complaining that the Rug Doctor rated high given its intended performance and use compared to a more professional machine which has a completely different intended performance and use, is a bit like complaining that a Maybach doesn't out-perform a fishing boat.
I've said before that a professional with a Rug Doctor will get better results than a homeowner with a truckmount, and I stand by that. Knowing the limitations and expectations of the machine with which you are dealing goes a long way toward getting expected or better-than-expected results.
For being the little "George Foreman grill wanna-be" that it is, the Rug Doctor rated high with the CRI because of its low power draw and dB level, as well as its soil-removal and appearance-correction performance when used according to directions.
This should in no way be taken to indicate that it's "as good as" a more powerful, bigger, noisier, gasoline-powered unit that could suck a bowling ball up the wand tube.
