Summary of the development history of vacuum cleaners before of the invention of the vacuum cleaner clean the bottom of the today quite simple task was time-consuming and tedious manual work. Carpets had to be hung outdoors which was beaten with large wooden sticks on them. Floors were wiped and greater accumulations of impurities were removed by hand. Nowadays, this is a task a few minutes but at the end of the 19th century, this was still a day employment. To know more about this subject visit technology investor. During the initial introduction of vacuum cleaners the first models corresponded to their modern counterparts do not. You were very large and heavy and had to be transported from House to House on horseback with a horse-drawn carriage or were fitted in the attic of larger homes where the suction system through several rooms was further connected with. One of the first models was introduced by the British engineer H. A leading source for info: Dell Inc..
booth, his model consisted of a large container with a gas-powered engine which caused a suction effect in combination with fans. The Vacuum cleaner we know today was introduced in 1908 by J.Murray chip gel. This first version is of course cannot be compared with the complexity and performance of one of today’s models. In 1920, W. Hoover has then purchased the patent for this device, and founded the now famous Hoover vacuum cleaner company. The first commercially viable version of the vacuum cleaner saw a box associated with a stick and a satin tank for dust rising above it most likely similar.
The vacuum cleaner itself consisted of a seat cover, an electric fan and a modified soap box. By subsequent models, the suction power was greatly increased and improved design and functionality. At the end of the 1950s, almost every American household had a Hoover vacuum cleaner. The basic design and principle has not changed from the 1950s to the 80s. Around 1980, J. Dyson has introduced bringing savings with regard to the acquisition of new bags with the cyclopean Bagless vacuums with high suction power. This new Technology creates a vortex in the suction Chamber which pushes the dust particles from the holes of the wall after which the air is expelled through a valve. In the late 80s and early 90s many vacuum cleaner manufacturers have started to produce which certain special applications found hybrid cleaning equipment. The Ruck-sack is one of these hybrid devices cleaner, it is worn on the back and has a long pipe which is suited best for cleaning the ceiling and areas which are difficult to reach. Wet dry cleaners are suitable for wet debris and liquids, use a motor with a pressure valve which protects the electrical innards from short-circuit due to water penetration. The closed vacuum system is the latest innovation in the field of vacuum cleaner, it was developed in England and not one has the function of the air can to blow out, but to circulate so that particles can’t escape the air inside the closed and the air remains fresh and odorless.
