Strangest thing..
When I worked maintenance at a Holiday Inn, they had a fleet of a dozen sanitaires of varying age and models. I kept them all in great running order and the last time I checked they still have most of them. Anyway, I have removed the following from a lot of vacs (not just those) the nastiest thing was a condom and more often than not the wrappers from such, nail clippers, jacks (the metal toy thingys), book of matches (what was left of it) straws, sugar packets, change, and lastly my absolute favorite a Barbie head. No joke, it was stuck inside a Clarke wide path machine.
