There is some debate on who invented the first vacuum, some say it's H. Cecil Booth, some say it's Daniel Hess while others say David T. Kenney deserves the credit.

different websites, including the records of the patents database and I present to you a snapshot on the history of vacuum cleaners, an overview of innovative men and women behind this often neglected household appliance that spans from the mid-1800s to the 21st century. Enjoy.
