As a home barista, you need to master all the above techniques to get the right espresso. If you make a little mistake you compromise your shot. As a result, you’ll get an average shot. Even if you know what it takes to get your shot right, there is very little room for error. Failed shots are pretty common with beginner baristas. You probably noticed in coffee shops that the shot differs from barista to barista.
3) This machine is crazy smart. It knows exactly when to clean itself, or tells you when to start the cleaning cycle. To clean it, all you do is insert a tablet in the coffee powder drawer and it does its thing. It knows when it needs water, when the filter needs to be changed, etc. In fact, since we have a water filter built into our refrigerator, we just use that filtered water in the coffee machine and therefore we don't need to use the expensive water filters. Bottom line, if you just pay attention and clean the machine on a regular basis when it tells you to, this is a no-brainer machine.
