Robert-
I know that situation: ".... it was the husband of my next door neighbor who said it to me. His wife simply laughed and said to her husband, "he knows that!""
Our neighbors, in the 1970s, had a M.Wards "suitcase" vac (Eureka), with vibra-groomer, a woven hose, and all the attachments (which btw, I did also end up getting from them in about 1981). I thought it was cool and wanted to play with it. I think I just helped myself to it one day when over at their house, where it was standing in the closet, and proceeded to take it out, but that didn't go over so well. They also had a Hoover constellation he kept in his neat garage for cleaning the car, which didn't do anything for me.
A relative had an green 60s Airway vac, which, when I was really small, used as a go-cart. The handle at the back was perfect for a 3 year old to push.
Later they moved to a new (1973) house with a Nutone Central Vac....
There were other friends who had kids my age and they had an Electrolux 1205. It was cool and I got possessive. It had a cord winder and it looked cool. lol. I remember getting into petty arguments with the kids on how to correctly plug it in. lol It had a neat round plug which was gray and had a unigue groove in it. I think they traded that for a Silverado in 1983.
When they came to visit, they tried the same possessiveness routine with our crappy Silver King vac. I was like, whatever. You can have it. lol.
The memories. lol.
As for the Lewyt: what an interesting concept with the low voltage PN. And what an interesting situation with the motor and it's potential lawsuit credentials.
I think I would get the hose cord set up as I suggested, alter the canister motor, or change it if it's a safety hazard, and put in a 120 volt motor in the PN. Unless, of course, one wants to relive the WHOLE Lewyt experience making sure their vac is plugged into a GFI outlet and they don't touch anything metal.
And yeah, there is certainly nothing on it that makes it "electronic". Back then, most people didn't know what electronic was. I remember now, turning the knob on the top and thinking 'it doesn't do anything' and how our Silver King didn't have a dial like that.
Apparently Lewyt is still made? A couple of vacs, one of which looks like brand new plastic style?
