What a fun thread, Doug! Rocket ship / UFO / atomic bomb vacuum cleaners from the 1940s and 1950s are my favorites!!
Here are a few.......
Air-Way 77 on an optional wheeled cart, poised at an angle and looking like it's ready to blast off into outer space!
Another view of the 77.
Hoover Celebrity -- looking exactly like a classic UFO from a 1950s flying saucer movie!
See what I mean?!
Clark commerical floor polishers. I love the robot-inspired motor hoods. "Gort! Klaatu-Barada-Nikto!"
The gorgeous Fairfax, looking like a gleaming chrome cousin of R2D2.
The Haley's Comet, surely one of the most bizarre vacuum cleaners ever conceived.
Space-age poem inside the bag chamber lid of the Haley's Comet.
OF COURSE, the Hoover Constellation!
Another robot-inspired floor polisher, the Johnson-Wax RP59.
Not a rocket ship, but the Kenmore Imperial "Bug-Eye" surely looks like an alien insect from some otherworldly realm in the cosmos.
OF COURSE, the Electrolux air-powered floor polisher attachment, another classic UFO design.
A fleet of Electrolux UFOS ready to blast off into outer space!
The stunningly gorgeous Modern Hygiene.
Designer Brooks Stevens' original design concept rendering of the Modern Hygiene.
We've already seen the Kenmore Commander tank above. Here's one that was disguised as a rocket backpack for the film "Rocketeer." This back-pack, which was stolen by thieves thinking they had stolen the actual backpack and not the mad scientist's vacuum cleaner, plays a key element in the plot of the story.
The Royal tank machine, which looks as much like a giant phallus as it does a rocket ship! (Did I say that??!)
