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: a handkerchief was placed on the armrest of the chair, and the mouth was attached to the handkerchief. As a result, the handkerchief was attached with a layer. dust. At that time, he made a vacuum cleaner, using a powerful electric pump to draw air into the hose and filter the dust through the cloth bag. 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.Robot Vacuum Cleaner M800
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 worked as an administrator in a store to reduce the burden of cleaning the carpet. He made a vacuum cleaner, which used a fan to create a vacuum to draw dust into the machine. Then blow 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, which sold quite well. The earliest household vacuum cleaner was designed reasonably, and there is not much change in principle since its development.
The earliest designed vacuum cleaners were upright. Wenle, Stockholm, Sweden, 1913. Goering invented a horizontal can vacuum cleaner
Vacuum cleaner classification
At present, civil vacuum cleaners are mainly divided into the following major categories:
1. Horizontal vacuum cleaner (Canister)
The types of vacuum cleaners that are more common in the Asian and European markets account for more than 80% of the overall market. It is characterized by its small size and convenient storage. Horizontal vacuum cleaners are also divided into "dust box vacuum cleaners" and "dust bag vacuum cleaners"
2. Upright vacuum cleaner (Upright)
American market is more common, suitable for large area carpet cleaning
3. Handheld vacuum cleaner (Handy)
It is compact and easy to carry and use. It is mainly used for cleaning inside the car, and it also has good effects on keyboards and electrical appliances. The disadvantage is that the power is small and the suction is not strong enough.
4. Bucket vacuum cleaner (Pot)
Commercial vacuum cleaners, mostly used by cleaning companies, hotels, and office buildings, are characterized by large capacity and water absorption.
5. Rod vacuum cleaner (Stick)
In recent years, it has gradually increased, mostly for charging type. It is characterized by compact size and convenient use.
6. Robot vacuum cleaner (Robot)
The high-end vacuum cleaner can be automatically cleaned and recharged, but the cleaning effect is limited, suitable for a very clean home environment.
