Hey Brandon,
The waxer you have pictured is a Handi-Waxer that Kirby replaced the Rollo Waxer with around the time the Sanitronic came out. To use the Handi Waxer, one would put a pouch of Kirby Carnuba (sp?) in the waxer, and slit it open with a knife at the bottom. The cap was used to keep the wax from drying out between waxings. The canister wands were reversed (straight wand on top, curved wand on the bottom) and inserted into the top of the waxer to make the handle. The user would step lightly on the top of the waxer to squeeze out the desired amount of wax, and then apply it to the floor. One would then attach the Miracle Head to the Kirby and buff the wax out to a beautiful shine. I've seen pictures of the Rollo Waxer in older instruction books, but never actually saw one in person.
