Industrial floor cleaning machines occupy a prominent place in the
janitorial industry. These machines enable thorough cleaning of large
spaces like schools and shopping malls in a fraction of the time it
would take a conventional team of workers. While the first industrial
cleaners date back to the turn of the 20th century, the technology has
evolved significantly in the succeeding decades.
The first part of the 20th century saw early manual vacuum technology evolve with the introduction of electric-powered vacuum cleaners. Hubert Cecil Booth introduced the first personal electrically powered vacuum in 1901, which was quickly followed by a series of larger designs intended for industrial purposes. The earliest of these were called "divided-weight" machines, which shifted the majority of the device's weight to the back to apply thorough pressure to the floor being scrubbed. Unfortunately, these couldn't replicate the amount of weight needed to provide a thorough polish and could be exceedingly difficult to maneuver.
The 1920s saw perhaps the most important innovation in industrial cleaning with the introduction of the "swing" machine. These resolved the earlier problems of cleaners by lifting the device's wheels off the ground and applying most of the machine's pressure to the cleaning brush. This has become the de facto technology used in floor cleaning. While the technology has advanced with the introduction of higher-power buffers, variable speeds, and new floor finishes, this basic innovation from decades ago continues to inform the machines of today.
