The development history of vacuum cleaners

In 1901, British civil engineer Booth went to the Empire Concert Hall in Leicester Square, London, to visit a demonstration of an American car dust collector. The vacuum cleaner uses compressed air to blow dust into the container, which Booth thinks is not very clever, because many dusts fail to blow into the container. Later, he did the opposite and used the vacuuming method. Booth made a very simple experiment: put a handkerchief over his mouth and nose, and inhale with his mouth to the handkerchief, resulting in a layer of the handkerchief attached. dust. So he built a vacuum cleaner that used a powerful electric pump to suck air into a hose and filter the dust through a cloth bag.

In August 1901 Booth obtained a patent and established a vacuum cleaning company, but it did not sell vacuum cleaners. He installed a vacuum pump powered by a gasoline engine on a horse-drawn carriage, served door-to-door, stretched three or four long hoses from the window into the room to vacuum, and the company employees wore work clothes. This is the predecessor of the late vacuum cleaner.

In 1902 Booth's service company was called to Westminster Abbey to clean the carpet used for Edward VII's coronation. Business has boomed since then. In 1906, Booth made a small household vacuum cleaner. Although it was called "small", the vacuum cleaner weighed 88 pounds (1 pound = 0.4536 kg), which was too bulky to be popular.

In 1907, the inventor of Ohio, Sbangla, made a lightweight vacuum cleaner. He was a manager in a store at the time, in order to reduce the need for cleaning the floor.

The burden of the blanket was made into a vacuum cleaner that uses a fan to create a vacuum that sucks the dust into the machine and blows it into the pocket. Due to his own inability to produce and sell, in 1908 the patent was transferred to Hoover, a fur manufacturer. At that time, Hoover began to manufacture a wheeled "O" type vacuum cleaner, which sold very well. This earliest household vacuum cleaner has a relatively reasonable design and has not changed much in principle since its development.

In 1910, the Danish company "Fisker & Nielsen" (now Nilfisk Advanced) sold the first Nilfisk C1 vacuum cleaner. The weight is about 17.5 kg, but because it can be operated by one person, it was well received by the market at that time.

The earliest vacuum cleaners were designed to be upright. In 1912, Wenler Goering in Stockholm, Sweden invented the horizontal canister vacuum cleaner, and Electrolux Electrolux became the founder of the vacuum cleaner.
