I know my mom had a Kenmore canister vacuum cleaner for decades before it finally broke -- it worked and despite being a plastic canister, it was clearly very well-made; she replaced it with a more "high-end" brand, I think a Sebo, that she doesn't like as much. I know they were always made for Sears by another company, just like Radio Shack's "exclusive" brands, but I don't know who made them in the 1980s. (It appears Panasonic had been making them during the 2000s, but some information I've found suggests that Panasonic got out of that business entirely in 2016.)
