They operate by using a motor driven pump instead of the classical manual force, having the necessary power to prepare the espresso.

Another type of espresso machine is the stove top model also known as stove top espresso maker. It has three containers: the bottom chamber which contains the water, the middle chamber working with a filter basket and the top chamber which has a metal filter. When heated, the pressure from the steam goes through a tube forcing the water through the filter basket up to the ground coffee beans releasing the coffee.
