I have an AirWay New Century vacuum cleaner (sani clean model) that I purchased NEW back in the 1990's. The power nozzle is shot, and I have been given very expensive quotes to replace it. I am thinking of selling the unit now, maybe on ebay, I have original box, manuals, all parts and even air filters. Should I try to sell without the power nozzle, or should I include it and say it is broken? The plastic base is cracked and the pigtail and roller brush are shot. Any comments would be appreciated.
