The First Vacuum Cleaner- In 1901, Englishman Hubert Cecil Booth invented the first successful Vacuum Cleaner. The machine worked well and was popular with rich people. It was also used in places such as Westminster Abbey, Buckingham Palace and Windsor Castle. Booth's cleaner was so large that it had to be pulled along by the horse, and six people need to operate it. The machines were only hired out, never been sold.
The upright Vacuum Cleaner was invented by American named James Murray Spangler in 1907. Spangler realized that his asthma was made worst by dust, and wanted to find a more efficient way of sweeping. He made the first upright vacuum cleaner with the help of a pillowcase tied to a broom handle and an electrical pump. Spangler sold the patent to his cousin William H. Hoover, who improved the invention and started a very successful business selling vacuum cleaner.
