In 1860 a manual vacuum cleaner was invented by Daniel Hess of West Union, Iowa. Called a 'carpet sweeper', It gathered dust with a rotating brush and had a bellows for generating suction.
The bulky device worked with a belt driven fan cranked by hand that made it awkward to operate, although it was commercially marketed with mixed success.
A similar model was constructed by Melville R. Bissell of Grand Rapids, Michigan in 1876, who also manufactured carpet sweepers. The company later added portable vacuum cleaners to its line of cleaning tools.
In 1901 powered vacuum cleaners using suction were invented independently by British engineer Hubert Cecil Booth and American inventor David T. Kenney. Booth also may have coined the word "vacuum cleaner". Booth's horse drawn combustion engine powered "Puffing Billy", maybe derived from Thurman's blown air design," relied upon just suction with air pumped through a cloth filter and was offered as part of his cleaning services.
Kenney's was a stationary 4,000 lb. steam engine powered system with pipes and hoses reaching into all parts of the building.
