Although the Esperta 2 and Genio are both Nescafe Dolce Gusto coffee machines, they differ in style, water tank capacity, and Hot/Cold beverage controls.
The Esperta 2 has a larger water tank capacity (60 ounces) than the Genio (45 ounces).
It also has two dedicated buttons for hot and cold beverages.
On the other hand, the Genio has a toggle stick at the rear for switching between hot and cold beverages.
