context_page_description: The manual vacuum cleaner was a type of non-electric vacuum cleaner, using suction to remove dirt from carpets, being powered by human muscle, similar in use to a manual lawn mower. Its invention is dated to the second half of the 19th century, when patents were granted to inventors in the United States, Britain, France, and elsewhere.
context_section_description: The Hoover from WW1 (see photo) is an example for a vacuum cleaner powered by a friction motor similar to 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 the floor until the motor ran down.
