Dishwashers have evolved significantly since Cochrane invented her machine in 1886. Modern dishwashers are more efficient and have more features, such as multiple wash cycles, temperature settings, and self-cleaning capabilities.

Some of the latest innovations in dishwashers include:

  • Built-in water softeners: Built-in water softeners remove hardness minerals from the water, which helps to prevent dishes from spotting.
  • Steam wash cycles: Steam wash cycles use high-temperature steam to sanitize dishes and remove tough stains.
  • Third racks: Third racks provide additional space for utensils and other small items.
    Smart dishwashers: Smart dishwashers can be connected to the internet and controlled remotely. They can also be programmed to start and finish wash cycles at specific times.


Josephine Cochrane’s mechanical dishwasher stands as the world’s first dishwasher, with her invention patented in 1886. This remarkable device transformed dishwashing from a laborious chore into a convenient and time-saving task. Cochrane’s innovation paved the way for the modern-day dishwashers we rely on today. Subsequent refinements and advancements have further enhanced their efficiency, contributing to improved sanitation, convenience, and water conservation in kitchens globally. The world’s first dishwasher by Josephine Cochrane has left an enduring impact on our daily lives, promising a future where clean dishes can be effortlessly achieved.
