Who Invented The Washing Machine

His name is Hamilton Smith, an American inventor and inventor of the washing machine.
In 1858, Hamilton Smith made the world's first washing machine in Pittsburgh, USA. The main component of this washing machine is a round drum, which contains a straight shaft with paddle shaped leaves. The shaft rotates by shaking the crank connected to it. In the same year, Smith obtained the patent for this washing machine. But this washing machine was labor-intensive and damaged clothes, so it was not widely used, but this marked the beginning of using machines for washing.

The following year, a washing machine using a pestle as a stirrer appeared in Germany. When the pestle moved up and down, wooden nails with springs continuously acted on the clothes. In the late 19th century, washing machines had developed into an octagonal washing cylinder with only a handle rotating. During washing, hot soapy water was placed in the cylinder, and after washing, the clothes were squeezed dry by a rolling liquid device.
