I have a Royal 8000 from about 1990 I think. It has a 6 amp. motor, and a brushroll with stiffners, and does a great job on my plush cut pile carpeting. It's not loud at all to me, but the newer ones with the higher amped motors are screamers. It's one that's in my rotation that I use on occasion, and love the way it handles. Mine has the old screw type height adjuster as opposed to the step on type, which suits me since all my carpet is the same pile. This may have been the model when they changed the setup mid-production and gave it a new model number, not sure though. It has maroonish color trim similar to the Kirby Legend II.
