Automatic espresso machines also have a pump that drives the water through the grouphead, but they go a step further than semi-automatic machines in that the machine also automates the extraction time. This means that a barista only needs to press the button to brew and the unit will control how long the shot pulls for either volumetrically or via an internal timer. These systems do not automatically grind, dose, and tamp the coffee, but some do include a pre-infusion feature to optimize tamping.
