John Thurman invented a gasoline-powered vacuum cleaner in 1899 and some historians consider it the first motorized vacuum cleaner.

Thurman's machine was patented on October 3, 1899 (patent #634,042). Soon after, he started a horse-drawn vacuum system with door to door service in St Louis. His vacuuming services were priced at $4 per visit in 1903.

Later, on August 30, 1901 a British engineer by the name of Hubert Cecil Booth patented a motorized vacuum that took the form of a large, horse-drawn, petrol-driven unit that was parked outside each building that fed long hoses through the windows.
