Detailed Specifications

Design and Build

The Mio has a sophisticated compact design and effortless handling. There are simple push buttons for brewing and steaming that are quite tactile in feel and work fine. The body is made of stainless steel, ensuring full durability, reliability, and long life. There is a complete mirror finish all around the body.

 A dedicated button is provided at the side of the case to turn off the steaming thermoblock which ultimately saves energy, and this feature is called ECO mode. The interface is super handy to use. There is also a feature to adjust pressure release from the brew group without opening the machine. Thus your espresso will be perfectly brewed.

The water reservoir can also be removed from the side instead of a top opening, making it very convenient to adjust in compact places with no headspace. These types of conveniences play a very important role in the machine’s overall performance.

Control Panel

There are three buttons on the front panel, one for turning the machine on and off, the second for brewing, and the third for steaming control. The key point here is that brewing is completely separated from steaming, so you can steam milk while the machine is brewing side by side. The steam function can be turned off to save energy. A PID screen on the top right portion of the machine can double as a timer for the shots to help you keep track of your shot.


Talking about the performance, the Mio makes outstanding espressos at just the press of a button without you knowing the skills of making espresso. This machine does not focus on customising the coffee but on performance to deliver pure espressos. The machine features everything for you to brew a perfect shot of espresso.

The machine may take 5-7 minutes to warm up. But the result is worth waiting for. The 1000W steam thermoblock reaches the steaming temperature, which helps in rich milk frothing. Despite having less steaming power than other machines, it will quickly steam up your cafe-quality milk for a medium-sized coffee.

You can also simultaneously do brewing and steaming with this machine without disturbing your brewing settings. This feature stands useful when you want to have steamed milk. And the catch here is that when you are done steaming the milk, you can just shut off the steaming thermoblock from the steam block switch. This will help the machine for saving power and focus on only brewing.

The 12oz can produce 3 cups of coffee, and the 32 oz to make 8 cups.
  • Second Steam Circuit – The 1000W steam thermo-block reaches the required steaming temperature with minimum heat loss within a few minutes. This will help you in steaming milk for cappuccinos and lattes.
