Some semi-automatic machines have a grinder, while others don't. The kind of machine you decide to purchase will be based on your personal preferences and budget.

A pump-driven espresso machine is akin to the stovetop moka pot, but uses an electric pump instead of steam to press the grounds. The boiler heats water until boiling point, and the pump pushes the hot water through the group head.

These machines are very popular in busy offices because they do away with the necessity of a grinder or dosing machine, as well as tamping. Since they do not have steam capabilities, a separate milk maker is required to make cappuccinos or lattes. Many cafes in Europe used steam machines to boost production and reduce brewing times. The first machines were heated over an open flame, resulting in unbalanced pressure and temperature. Angelo Moriondo, an Italian inventor from Turin, is credited with creating the first machine capable of brewing coffee without steam. The most popular type of espresso machine in use today is a pump-driven machine. These machines utilize a portafilter to hold the ground espresso beans. When the valve is switched to the espresso position, the espresso is extracted by water that is under 15 atmospheres pressure from the vessel that heats. When the brew cycle is completed, the porta-filter is removed and the drip tray is empty to clean. Automated espresso machines automatize semi-automatic systems, by controlling the extraction time based upon internal or volumetric timers.
