Vacuum cleaner
The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners. The first manual models, using bellows, were developed in the 1860s, and the first motorized designs appeared at the turn of the 20th century, with the first decade being the boom decade.
Kirby Company
The Vacuette Electric, introduced in 1925 with its removable floor nozzle and handle, became the forerunner of today's multi-attachment Kirby vacuum models. In 1935, the company introduced the Kirby Model C, the first product to carry Jim Kirby's name. The Vacuette was also briefly offered as a manual vacuum cleaner, utilizing a spring-loaded worm gear driven by pulling the vacuum cleaner backwards, then when pushing the machine forward, the worm gear would power a turbine that provided the suction needed. As long as the cleaner was consistently pulled backwards, tension in the spring would remain constant and the turbine would continue spinning. It was designed for rural areas that didn't have electricity, and was very similar to the carpet sweeper.
