Kirby history.
In the Kirby timeline in reply #18, it states that the first two models are unknown. They are 'The Domestic Cyclone,' a non-electric, using water to catch the dust. It was Jim Kirby's first vacuum cleaner, and he improved it in 1907, calling it 'The Domestic Cyclone Electric.' He followed that in 1910 with what he called 'The Broomstick.' I hope this clears up any questions.
