Humanity's Greatest Inventions:

No. 1. Indoor plumbing (flush toilet/sewerage system)

Between this and hand washing, the greatest single medical intervention ever. Prevents cholera etc. Antibiotics came much later.

No. 2. Washing machine (for clothes)

Greatest labour saving device ever, for an absolutely necessary ongoing household task.
