Those Eureka made canned ham cannisters with PN sure were powerful machines but were SOOO HEAVY to lug and pull around. They were also prone to getting hung up on doorways, furniture, ect.
A neighbor lady we had in the mid 1970s had the orange/yellow version with the push buttons,and woodgrain PN,,i dont remember if it had a headlight tho,,i want to say it did not.
She also had thick wall to wall shag carpet and shag on her long stairway.
She had "Indoor/Outdoor"(very low tight pile) carpet in her kitchen and bathrooms and you would have to lower the suction of the vac or else the PN would stick to it, and you couldnt push or pull the PN. She liked for her wood panel walls to be vacuumed once in awhile, and i remember that extra wide floor and wall brush sure came in handy.
I was just a kid then, but she would pay me a couple of dollars (big money on those days!) to come over and vacuum her house, top to bottom. She would leave and run errands and i would happily vacuum away with the Eureka. Typical of small town, 1970s Midwest.
That Really was an excellent vacuum, but not very user friendly as far as cleaning a large home with alot of stairs, furniture, and thick shag carpet. After about the first hour, my arm would be sore from dragging that thing around, and having to go back and unhook it from whatever it got held up on. Sure was good exercize tho!
