I have a green Hoover Celebrity Quiet Series and the power nozzle for it is broken (the plastic on the base is broken in half and part of it missing, it's not a motor issue that I can fix)... it happened during a move and I've been looking on Ebay for about a year now and have not been able to find one.
If anyone here knows of one, or has one that they want to sell, please let me know! Mine is green, but I can always use a the base of the donor and use my "hood" to make the color match my machine. Mine is the one with the bare floor on/off pedal and it has the quadraflex agitator.
