The world’s first upright vacuum was invented in 1908 by a department store janitor named James Spangler. Inspired by commercial cleaners available at the time, Spangler created his lighter, more portable model with the residential market in mind, and investors took notice. Soon after the Electric Suction Sweeper Company came into being, it was purchased by a businessman looking to get into a new industry. William Hoover bought the vacuum company and became, perhaps, the most recognizable name in carpet cleaning history. From Hoover to Dyson and beyond, today's upright vacuums still rely on the same concept of beating, sweeping, and suctioning dirt out of rugs and carpets all over the world.
