The origins of this vac lie in the debut of a sleek bagged upright by Eureka in the 1990's. It was called the Eureka Victory and I think it was Eureka's second clean-air, bag first bypass upright after the Excalibur. This Victory featured a "Back-Saver" handle which was bent in a certain way to allow you to get under furniture without too much stooping. It had the same on-board hose as this Electrolux which allowed you to grab it at any time for above the floor cleaning, similar to Panasonic's "Quick Draw" hose.
It only rated a mediocre "good" for carpet cleaning in Consumer Reports testing, and I was never a fan of the cheap combination dusting brush/upholstery nozzle which stored on the back of the handle.
At some point, Eureka adapted the design to create a bagless version featuring the dust container shown on this Electrolux. They branded this "The Whirlwind."
That's a bit of the history of this vac!
