New Rainbow Power Nozzle
Mark,
I do like the new design but for a regular user, I don't think I would need to upgrade. I never had any problems with my original center belt power nozzle. I just checked my belt on the original power nozzle and it seems fine. It has seen a LOT of use. This is clearly just a better execution for longer belt life and like the Rainbow itself-better air flow and suction over time. I see no decrease in the quality of the new unit.
Since you also have an Electrolux you will undertand but when I used the new power nozzle on the bedroom carpets,I could really tell the difference in the LOOK of the carpet. My Electrolux has a much softer brush roll and although I am SURE it cleans very well, it does not make the carpet look as nice.
This power nozzle gives a very "finished" look to the carpet without wheel or brush roll marks,just a full width of carpet nap standing errect. I also did notice how well the fuller end brushes get the fluff along the baseboards and around the furniture edges. You can tell the suction is the full width of the nozzle because of the design of the vents and grooves built into the bottom plate.
Also you can feel an increased air flow level by just holding your hand above the running nozzle.
