The first successful vacuum cleaner was invented in 1901 by Hubert Cecil Booth, a British engineer.

Booth's machine took the form of a large, horse-drawn, petrol-driven unit, which was parked outside the building to be cleaned with long hoses being fed through the windows, and it took four to six people to operate it.

Of course, these early versions of vacuum cleaners were bulky, noisy, smelly and commercially unsuccessful.
