When was the washing machine invented?

The first washing machine was designed by H. Sidgier of Great Britain in 1782.

The first patented washer in the United States was by Nathaniel C Briggs in 1797. It was a manual device. (The US Patent Office was destroyed by fire in 1836, so there are no details or drawings.)

The first electric washing machine was invented in 1906 by Alva J. Fisher.
