Around thirty years ago I bought an upright Vorwerk Vacuum Cleaner when we lived in Patterson Lakes in Victoria.  It was demonstrated in-home by a salesman and not sold in shops at the time.  Not sure how I found the salesman.  Could have been one of those shopping centre demonstrations or something.  It was a great vacuum and lasted for years.  About the only thing I didn't like was that it had a cloth dust bag.
Somebody please correct me if I'm wrong, but I'm sure I saw them in Godfreys a couple of years ago.  Wonder if they still carry them.
  The vacuum is in the same colors as Thermie.
 
Ohhhh Lee, that would be enough to make me get one
