The early history of the vacuum cleaner is filled with large machines, experimental designs, and competing approaches to dust removal, but one of its most fascinating stories centers on a janitor named James Murray Spangler. Working as a cleaner while dealing with asthma, Spangler reportedly became frustrated by the dust generated through traditional cleaning methods and began experimenting with a device that could remove dirt through suction rather than simply moving it around. According to historical records preserved by Hoover and the University of Cincinnati, Spangler developed an electric suction sweeper in 1907 using readily available materials, including a fan motor, a broom handle, and a pillowcase that acted as a dust collector. The machine was crude by modern standards, but it represented an important step in the development of practical household vacuum cleaners.
