A manual vacuum cleaner was a type of non-electric vacuum cleaner, using suction to remove dirt from carpets, and powered by human muscle, which use is similar to a manual lawn mowers. Their invention is dated to the second half of the 19th century, when patents were granted to inventors in the United States, England, France, and elsewhere.
In the United States, several dozen firms produced manual vacuum cleaners in the early 1900s, 1914 being the peak year. Three different models were sold by Sears, Roebuck between 1909 and 1917. Their main market was in rural areas, where as late as the mid-1930s, 90% of American farms (over 5 million) did not yet have electricity.
These household appliances created suction by either a pumping action, bellows, a piston being pushed up and down a tube, or had a fan driven by the wheels. Most required the efforts of two people. The models operable by one person were less efficient, but none were truly labor-saving devices or delivered the cleaning efficiency they promised. Besides hand-operated models, foot-operated models were also available, and according to a Swiss source there was even one where the operator sat in a rocking chair, rocking back and forth to produce the energy needed to create suction.
The type of vacuum illustrated is powered by a friction motor similar but larger than those powering toy cars. To power it, the user would run it forward and back a few times, and then lower the intake to the floor and clean until the motor ran down.
