A vacuum cleaner
A vacuum cleaner is a device that collects dust and dirt from various surfaces due to its absorption by air flow. The first model working on gasoline was invented by English engineer Hubert Booth in 1901. The device was very inconvenient and bulky, it was installed on the street and used for cleaning carpets. But in 1921, the housewives saw a model from Model V, which was the parent of the modern device.
The operation of all types of vacuum cleaners depends on the power consumption, which figures range from 1300 to 2000 watts. As well as the power of suction of dust, which varies from 250 W for small and from 300 W to 350 W for cleaning highly contaminated rooms or high-speed cleaning.
There are several types of vacuum cleaners, differing in design and functionality. Vacuum cleaner for dry cleaning is used to perform small areas of work. Floor, carpet, furniture, clothing, parquet - the main objects for cleaning. Vertical vacuum cleaners are used when cleaning large areas.The range of actions of such devices is wide, but they are noisy and massive. The washing vacuum cleaners carry out functions of dry and damp cleaning. Appliances not only collect dust, but can wash tile and windows, collect spilled liquid, sanitize a room, and even clean a clogged sink or bathroom.
