There were many people who had a hand in âinventingâ the vacuum cleaner. Every invention and patent has made minor improvements and has evolved into what we use today. Many people are under the assumption that H. Cecil Booth, a British engineer, was the first person to patent the vacuum cleaner in 1901.[1] The first person to patent a version of the vacuum cleaner is Daniel Hess, from West Union, Iowa, in 1860.
