I know several of you also have central vacs with and without HAH. Does anyone know the difference between the Turbocat and the Turbocat Zoom nozzles? I know that the Turbocat is the older model but does the Zoom do a better job grooming the carpet? My system came with the Edge electric powerhead which does a wonderful job but I also purchased a Turbocat to keep upstairs with the bedrooms. It seems to just float over the surface and doesn't even remove footprints from the carpeting. The difference between the Turbocat and electric nozzle is night and day in terms of those awesome "lines" in the rug. Do you see the same thing in your house? If the Zoom is truly better I may invest in one, I just don't want to spend more money on a product that will do the same job. Thanks in advance!
