There are two types of espresso machines, traditional and automatic. The automatic espresso machine is often referred to as a super-automatic espresso machine. The operating styles for the traditional espresso machine are manual (lever-operated or paddle), semi-automatic, and volumetric dosing (automatic). You may have noticed that we have several categories for espresso machines. We created these categories to assist you in narrowing our selection of espresso machines so you can easily find the specific type of machine you may be looking for. Our additional categories are “Home|Office” for lower volume, “Precision” for machines offering brewing temperature control and “Distinctive” for machines offering a unique or artistic style.
