Throughout the latter part of the 20th century, a number of inventors patented various coffeemaker designs using an automated form of the drip brew method. Subsequent designs have featured changes in heating elements, spray head, and brew-basket design, as well as the addition of timers and clocks for automatic-start, water filtration, filter and carafe design, and even built-in coffee grinding mechanisms.
A steam-driven unit operates by forcing water through the coffee by using steam or steam pressure. The first espresso machines were steam types, produced when a common boiler was piped to four group heads so that multiple types of coffee could be made at the same time. This design is still used today in lower-cost consumer machines, as it does not need to contain moving parts. Also, steam-driven machines do not produce as high of a pressure for extraction compared to pump-driven. This results in the crema, a hallmark of an espresso, being of lower quality.
These machines automatically grind the coffee, tamp it, and extract the espresso shot. The operator only has to fill the bean hopper and, if the machine is not connected to a water line, add water to a reservoir. Some models contain an automated milk frothing and dispensing device. Super-automatic machines take away the ability to manually tamp and grind the coffee, which may affect the quality of the espresso.

Pierce's design was later improved by U.S. appliance engineers Ivar Jepson, Ludvik Koci, and Eric Bylund of Sunbeam in the late 1930s. They altered the heating chamber and eliminated the recessed well which was hard to clean. They also made several improvements to the filtering mechanism. Their improved design of plated metals, styled by industrial designer Alfonso Iannelli, became the famous Sunbeam Coffeemaster line of automated vacuum coffee makers (Models C-20, C-30, C40, and C-50). The Coffeemaster vacuum brewer was sold in large numbers in the United States during the years immediately following World War I.
If you want a fully automatic machine that makes a great espresso, the Jura is a great option. It has a built in burr grinder, meaning you'll get the freshness of a semi-automatic machine. It allows you to choose from three cup sizes, meaning it will brew a coffee, an espresso, or a ristretto (a short shot). You can also choose the strength of your coffee, selecting between dosage sizes of 8–10 grams. The machine has a relatively easy to use touch screen. And, the spout that dispenses the coffee has an adjustable height, making it possible to maximize your crema depending on your cup size—the closer to the cup the spout, the better the foamy creaminess will be on top. It includes a milk steaming compartment and steamer, which creates a creamy, well-incorporated foam.
