Very cool. I have often wondered what the old Warsaw Pact used to vacuum their homes with, or if they even had vacuums. Bet they were confined to the elite nomenklatura and not widely available to the proletariate.
I'm sure the motor turned the opposite direction of a Hoover motor.
The Soviets were funny that way. Where all the rest of the world has the "right hand rule" in physics, the Soviets had an equivalent "left hand rule", and where all western helicopters (except the French!) main rotors turn counter clockwise when viewed from the top, Soviet helicopter main rotors all turned clockwise. They were resolutely perverse that way.
