Question

who invented washing machine​

Answer 1

Answer:

Alva J. Fisher has been incorrectly credited with the invention of the electric washer. The US Patent Office shows at least one patent issued before Fisher's US patent number 966677 (e.g. Woodrow's US patent number 921195). The "inventor" of the electric washing machine remains unknown.

Answer 2

Answer:

Alva J. Fisher

Explanation:

Alva J. Fisher invented the washing machine according to some sources. But, the US patent office says that there was at least one washing machine before the machine of Alva.

So, the actual 'inventor' of washing machine is unknown.
