The newest Rainbow should give a good go, did the Rainbow demo vs. new Kirby about a month ago. The Rainbow killed the Kirby with a new bag at that on a demo standpoint. 50 strokes back and forth on the carpet with the Kirby, did 3 inches of that same carpet, 1/2 inch of dirt on the test cloth. Granted that is how it is supposed to work, but 1/2 inch was might impressive for 3 inches of a single stroke. I suppose if you did a very good cleaning with any quality vacuum the demo is going to be a lot less impressive.
