Ok, since I just turned 16 (May 31st,) I have decided to give myself a birthday present of my own. One of the options for my present would be to get my Kirby DS 50 refurbished. How do I go about doing that? I know you need the manual page that has the serial number on it but, who do I contact? How much will it cost? Can I request a Sani-emptor? Mine has the regular bag right now. Also, where can I get a manual? And where on my Kirby is the serial number located? Thanks!
