Vacuum Cleaners Discussions

I am 74 and have repaired vacuums as a hobby for many years. This winter has been so bad for my work as an arborist that I have taken to vacuum repairs. I enjoy the challenge and want to declare that the designs of vacuum cleaners prove the old adage"A chain is only as strong as its weakest link". I am new to this Forum but not to Internet forums. Last week I joined www.abbysguide.com forum and today the very small Yahoo Group vacuum_cleaners (only 14 members). I will post photos of the Fantom's electro-mechanical switch mechanism and a plastic spring loaded device that was loose inside it. I cannot find a source for a schematic or parts so I am having to mend broken parts with two-part epoxy. A plastic spacer inside the agitator brush broke into four parts so I will turn a replacement out of dogwood or hard maple on my General-Interational wood lathe. I am doing the best I can without information and my customer has no owner's manual. Manuals seldom have a parts diagram detailed to the full extent. I am also reconditioning my own Bissell 8975 and a Hoover Conquest 14" C-1418 that belongs to our church. Next week while volunteering at a museum I will work on a carpet shampooer that is stuck...probably a gummed orifice. My search thus far has shown that Fantom models kind of entered the market about the time Dyson did. It may be so that AMWAY bought the Fantom line for their distributors to sell from their Catalog. If anybody out there can help my plight please toot your horn and sound off. Thank you!
