Clean air and such
Pete,
Clean air refers to motor/bag position. A clean air upright would have the motor behind the bag, pulling the dirt into the bag, such as the DAM or Panasonic.
Dirty air would have the motor in front of the bag, with the dirt passing thru the fan and being pushed into the bag, such as Kirby, Convertibles ect.
Publicly, Hoover told people they dropped the clean air DAM because they knew the dirty fan cleaned carpeting better.
To Chris(Gizmo):
It took me a long time to get any Hoovers from Australia. My friend John was not finding much of anything at all. He's got some connections now, and has a regular pipeline of them coming thru. I've also sent him quite a few machines, so we just trade back and forth. Its pricey to ship back and forth, but neither of us really cares. I think my most expensive Aussie machine would be the U7008 I won from ebay last year. It was listed as local pickup in Brisbane, and I emailed the seller to see if they'd be willing to ship it to Sydney for me. She was, so I bid and won the vacuum. She shipped it to John, and he sent it Airmail to me. By the time the cleaner arrived on my front steps, I had shelled out about $300 USD. Yeah pricey, but the machine is beautiful, and the wonderful lady I bought it from even sent me the owners manual seperately, as she discovered it after she'd shipped the cleaner.
Turbo-Lark: I like it, very good cleaner, but for me the handle is too short. Mine is not super loud, but I do have a UK made turbopower Jr which is ear splitting.
Roselle is a Chicago Suburb, just as Lockport is. Lockport is a southern suburb, Roselle is northwestern. I'm about 8 miles due west of O'hare Airport along Irving Park road. Distance from Roselle to Lockport would be 40-50 miles I'd guess.
Thats some interesting insight on the Dynamatic name too.
