Hey there Doug...nice Viking vac from Eaton's (how I mis
You know, one of the reasons I dislike bagless vacuums was because of the Sanyo "Cassette" canister vacuum my father brought home from work one summer evening in the early 1970's. Dad was the advertising producer for Sanyo in Canada from the late 1960's for about 15 years (he created the "Sanyo Makes Life's Good Things Better" slogan).
Anyhow, because Sanyo was so involved with audio "cassette" players at the time (they may have even invented the audio-cassette..... not sure), they decided to use the same term for their "easy-to-remove" dirt container on their bagless vacuums. The model dad brought home was from a few years ealier than the wood-grain model in your pic above. It was a beautiful blue canister vac, with grey tools. The hose was very, very short! About 5 feet! But it was electrified so you turned the machine on with a switch on the hose handle.
Getting back to my dislike of bagless machines: Cleaning this vac was a messy process. And neither my mother, nor our very nice cleaning lady, cleaned out the machine - it became my job! No matter how much dirt was contained in the container, the secondary cloth bag ended up full of fine dust that had to be shaken out. Lucky thing we had an indoor garage because that was the only place I could clean out the vac without making a mess inside the house!
Compared to changing the monster-size F&G bag in our new Eureka golden Rugulator upright twice a year, the bagless canister forced you to go through a tedious and messy process.
On the positive side, it was very powerful little vac, and very lightweight and easy to shlep around. Biggest design flaw was that if you sat it on end on carpeting to clean stairs or high bookshelves, you completely blocked the exhaust.
Sanyo came out with a similar vac the next year that was red and had a transparent dust cassette....
