In 1901, British civil engineer Booth visited the United States for a demonstration of a car dust collector in the Imperial Concert Hall in Leicester Square, London. This type of vacuum cleaner uses compressed air to blow dust into the container. Booth believes that this method is not very clever because many dusts are not blown into the container. Later, he did the opposite. With the vacuum method, Booth made a very simple test: put a handkerchief on his mouth and nose, inhale the mouth with his mouth, and the result was a layer of handkerchief. dust. So, he made a vacuum cleaner, using a powerful electric pump to draw air into the hose and filter the dust through the cloth bag.handheld vacuum cleaner
In August 1901, Booth patented 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, and the door-to-door service put three or four long hoses out of the window into the room to vacuum, and the company employees wore overalls. This is the predecessor of the late vacuum cleaner.
In 1902, Booth's service company was called to Westminster Cathedral to clean up the carpet used in the VII Edwards coronation ceremony. Since then, business has become increasingly prosperous. In 1906, Booth made a small household vacuum cleaner. Although it was called "small", the vacuum cleaner weighed 88 pounds (1 pound = 0.4536 kilograms). It was too bulky to be popular.
In 1907, the inventor of the United States, Ohio, made a lightweight vacuum cleaner. He was a manager in a store, in order to reduce the cleaning.
The blanket is made up of a vacuum cleaner that uses a fan to create a vacuum that draws dust into the machine and then blows it into the pocket. Because he was incapable of producing and selling, he transferred the patent to fur manufacturer Hoover in 1908. At that time, Hoover began to manufacture a kind of "O" type vacuum cleaner with wheels, and began mass production of the vacuum cleaner. Hoover was established for this purpose, and the sales were quite good. The earliest household vacuum cleaner was designed reasonably and developed. There aren't too many changes in principle today.
In 1910, the Danish "Fisker & Nielsen" company (now Liqi Advanced) sold the first Nilfisk C1 vacuum cleaner. The weight is about 17.5 kg, but because it can be operated by a single person, at the time, it was well received by the market.
The earliest designed vacuum cleaners were upright. In 1912, Wenler Goering of Stockholm, Sweden, invented a horizontal canister vacuum cleaner, which became the founder of the vacuum cleaner. Vacuum cleaners have a history of more than 150 years.
