How does a vacuum cleaner work?

Electric vacuum cleaners use suction to pick up particles.
A motor-driven fan creates a partial vacuum that sucks up dirt loosened by a beater brush and deposits it in a back or another type of collector.
(Vacuum cleaner fan blades spin as fast as 18,000 spins a minute; jet engine blade spins only 7,000 to 8,000 times a minute.)
An upright vacuum is a single unit with a bag usually attached along the backside of the handle.
The canister type has a long, detachable cleaning wand attached to a rolling unit that houses a more powerful motor, the fan, and the dust bag.
The vacuum cleaner became popular in the twentieth century when electricity became widely available.
But even before then, there were manual models that used the same idea—low-pressure suction.
These sweepers required the household laborer to create the suction by hand, working a bellows or cranking a pulley device.
Electric vacuum cleaners are one of the great labor-saving devices of the modern era.
They made a cleaner home possible in a fraction of the time.
