Vacuum Cleaner History
In 1901, British civil engineer Booth visited the Imperial Music Hall in Leicester Square, London to witness a demonstration performance of an American car dust collector. This vacuum cleaner uses compressed air to blow dust into the container, but Booth believes that this method is not clever because many dust particles cannot be blown into the container. Later, he took the opposite approach and used the vacuum method. Booth conducted a simple experiment: he covered a handkerchief on the armrest of a chair and sucked it off with his mouth, resulting in a layer of dust adhering to the handkerchief. At that time, he made a vacuum cleaner by using a powerful electric pump to suck air into a hose and filter dust through a cloth bag. In August 1901, Booth acquired and established a vacuum cleaner company, but did not sell vacuum cleaners. He installed a vacuum pump driven by a gasoline engine on the carriage, provided door-to-door service, and inserted three or four long hoses from the window into the room to vacuum. All company employees put on work clothes. This is the predecessor of later vacuum cleaners.
In 1902, Booth's service company was summoned to Westminster Abbey to clean up the carpet used for the coronation ceremony of King Edward VII. Afterwards, business flourished day by day. In 1906, Booth created a small household vacuum cleaner, named "Small", which weighed 88 pounds (1 pound=0.4536 kilograms) and was too bulky to be widely used.
In 1907, Ohio inventor Spengler made a lightweight vacuum cleaner. He was working as a store manager at the time and created a vacuum cleaner to reduce the burden of cleaning carpets. He used an electric fan to create a vacuum and sucked dust into the machine, which was then blown into a pocket. Due to his own inability to produce and sell, it was transferred to fur manufacturer Hoover in 1908. Hoover began manufacturing a wheeled "O" - shaped vacuum cleaner back then, which sold quite well. This earliest household vacuum cleaner had a reasonable design and has not undergone significant changes in principle since its development.
The earliest designed vacuum cleaner is upright. In 1913, Wenler Goering from Stockholm, Sweden invented the transverse can shaped vacuum cleaner
