Hi rugsucker.
As far as I recall, the C-A used the hose that went with the first model G, and the power nozzle hung on hooks at the back of the unit. The complete C-A featured a holding tank and baffle for wet pick-up, as well as a rubber hose, and squeegee floor tool. In most cases however, it was used as a regular vacuum cleaner with standard hose, tools and so on.
Right now I'm saving up to get things at the convention, but in the not so distant future I may consider buying it. Send me a private email on what you're asking for it, as on rare occasions, I've met a 'high offer.' Time is not a factor here, as this would be in my display room which I'm in the process of building.
I'll know more on this post convention.
Alex Taber.
