The carpet sweeper was invented by Daniel Hess in 1860. The design of this machine had bellows for suction, as well as rotating brushes to collect dirt. An improved version was patented in 1865.
The machine then called the vacuum cleaner was invented in 1901. The author of this development is Cecil Booth. True, the vacuum cleaner worked on an internal combustion engine and was so large that it was transported by horse-drawn carriage, and then by car.
Then in the 1920s, janitor James Murray Spangler invented a carpet sweeper. This device consisted of a broom handle, soap dish, pillowcase, electric motor.
The first plastic vacuum cleaner was produced in the 1930s. In 1952, the forerunner of modern vacuum cleaners appeared. Edited by Hoover.
All vacuum cleaners have used bags to collect garbage from the very first moment. But in the 1970s, a bagless model was introduced, which was successful among buyers. Today, most vacuum cleaners are bagless, just like me.
In addition, in 1996 Electrolux launched the first robot vacuum cleaner. True, its sensors were not very good, so it was eventually discontinued.
