A brief history of the vacuum cleaner

The first to patent a machine for cleaning was David Hess in 1860. become housewives across America was to help the carpet, a property on the waves of immigrants from Europe brought to cover their bare wood floor and keep the dust and dirt to a minimum. If they were dirty, had to be made, somehow suspended in the air and then hit with a wooden stick or a heavy metal rod.

A little 'later someone invented a small, tennisRacket-looking device called a beater for precisely this purpose. Mr. Hess soon realized that there's probably an easier way to clean carpets without all the confusion and disorder and invented the carpet sweeper, which had a rotating brush with a bellows system that created suction combined. to capture his amazing invention, two chambers of water, dust and dirt end. The only problem with the car Mr. Hess' is that there's no evidence was ever produced.

After the invention of Mr. Hess' iscome for a period of wild and crazy inventions, which sought to achieve the same thing. In late 1870, Melville Bissell (sound familiar?) Marketed a carpet sweeper that picked up dirt and dropped it into a pan behind the rotating brush. In 1899, John Thurman invented a vacuum cleaner than gasoline powered version is credited as the first. In 1901 Hubert Booth of London invented the electric vacuum, a unit so large that it was parked outsidethe house and a pipe 100 feet long snaked its way inside and did the dirty work.

The device was so popular that in all parts of London held vacuum housewives enjoy the event. It was not until 1908, when James Spangler, a janitor in Ohio, the cleaner invented the first portable, suction - the forerunners of today's high technology machines. He sold his patent to his cousin's husband, William Hoover (also familiar?) And the rest, as they say, is history.
