And if you're worrying about damaging fibers on a rug, the rug needs to be in a rug washing shop.  Team up with a rug washing business and have them set up a pick up and drop off from your place
Or, if you are wanting to play with a few delicate rugs yourself and are messing with those rugs that might get damaged if vacuumed, get the dry dirt out another way by vacuuming the back of the rug upside down.  YOu'll be surprised how much dirt vibrates down out of the rug just through vibration.  Actually, it's the same concept of vacuuming normally from the beater bar, but instead of the suction of the vacuum removing the dirt, gravity is doing the removing.
