Hoover Industrial Vacuum Cleaners?

[betam64]

Hey all! I recently came into possession of some old Hoover advertisements, and among those, are a few "Industrial Vacuum Cleaners."
These are the models of the advertisements:
- 7310 / 7315
- 7330 / 7335
- 7390 / 7395
- 7350
- 7370

I liked some of them, and wanted to get an idea of the availability; I can't even find a mention of those cleaners online. Granted, my search wasn't thorough or comprehensive by any means, but it was enough to give me the idea that these cleaners aren't common.

Does anyone happen to own one of these machines, and if so, what are your experiences with them? I'm not interested in buying one right now, but I would like to learn more about them.

I attached two example images (not all of them) so you get an idea of what I'm talking about.

@betam64 can I have a picture of all the literature about? If so have I permission to save to my device?
Thanks.

Damien, just sent you all the files. You're welcome to save them and/or distribute them wherever!
