\n<\/a>\"hand<\/a>“The easiest way to utilize\u00a0pump vacuums<\/a>\u00a0(picture below, left) was to have two people operate them. One person would pump the vacuum while a second would use the hose and wand or tools to clean. A common sight was a daughter pumping the handle while mom did the cleaning. Most early vacuum cleaners were expensive for the time. The well-to-do often would purchase the cleaning contraptions to ease the workload of their servants or housekeepers.”<\/p>\n


\n<\/a> “Bellows operated vacuums<\/a> appeared in several styles and shapes. Some early vacuums utilized a single bellows. This made the cleaner less efficient because there was no suction as the bellows closed. Suction was produced only as air rushed into the bellows as it opened. To make the machines more useful, bellows were installed in pairs and offset to allow one to open while the other closed.”\u00a0Picture right: a bellow-operated\u00a0Star Vacuum Cleaner<\/a>.<\/p>\n

\"Hand<\/a>“In their day,\u00a0wheel operated vacuums<\/a>\u00a0approached the cutting edge of early technology.\u00a0 They exhibited a sophistication that was not present in earlier vacuum designs.\u00a0 This style of machine provided powerful and continuous suction for its user.\u00a0 The increase in vacuum even allowed for larger diameter hoses and bigger cleaning tools.\u00a0 Typically, one person cranked the wheel while another cleaned with a wand or hand tool.”<\/p>\n

“Friction vacuum cleaners<\/a>\u00a0are based on an ingenious concept conceived by James Kirby. They utilize the driving force of the rear wheels to power the cleaner. This style of vacuum derives its power when the operator pushes it across the floor. The wheels contact the floor and turn the axle. This energy is transferred to the fan via a worm gear during every forward motion of the machine. The front wheels are connected to a brush roller to create a sweeping action. These machines look like an early electric upright vacuum, but do not need electrical current to run. As a result, they have no electric motor, cord, plug, or switch. This makes them lightweight, quiet, and cost free to use. Friction vacuums were popular well into the 1940’s in communities where electricity was not available.”<\/p>\n
