I remember them when they were new. Lots of problems. I'm shocked one survived, but it probably wasn't used.
I just (within the last two weeks) threw away six packages of genuine bags for that machine. I didn't think any of them were still here.
I traded one in on a Rainbow D3 in the early 1980's when the Regina was still young. The power head pushed hard, and was too tall to fit under anything. The neck on the rug/floor tool was already broken when I got it as a trade-in. It did belch dust, but the bags were so thin. Easy to trade for a Rainbow. I'll bet most of the motor bearings shot craps after a short period of time, due to all the dust in the motor.
Interesting machine. What's even more interesting is that Air-Way manufactured it as an "Air-Way" for a period of years in the 1990's.
