11 mars 1901 - vacuum cleaner
Description:
The end of the 19th century saw the introduction of powered cleaners, although early types used some variation of blowing air to clean instead of suction.[5] One appeared in 1898 when John S. Thurman of St. Louis, Missouri submitted a patent (US No. 634,042) for a "pneumatic carpet renovator" which blew dust into a receptacle.[6] Thurman's system, powered by an internal combustion engine, traveled to the customers residence on a horse-drawn wagon as part of a door to door cleaning service.https://en.wikipedia.org/wiki/Vacuum_cleanerAjouté au bande de temps:
