Vacuum cleaner
The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners. The first manual models, using bellows, were developed in the 1860s, and the first motorized designs appeared at the turn of the 20th century, with the first decade being the boom decade.
Central vacuum cleaner
In 1869 Ives McGaffey patented the first portable vacuum cleaner, or “sweeping machine”. The portable vacuum cleaner is the parent product to the modern central vacuum system.
