What is that? Some kind of bizarre retro-futurist jet car? - Its actually a vacuum cleaner (sans hose) produced by Panasonic in Japan in the 1960's.

I think that this was the first plastic-constructed vacuum cleaner ever built, and with its swivelling track wheel on the bottom and light weight durability (along with gorgeous futuristic looks) it helped to usher in the new era of plastic consumer goods.
