Keurig tried to follow in Nespresso's footsteps with their Keurig Rivo brewer, which brewed specialty beverages like lattes and cappuccinos.
Unfortunately for Keurig, the Rivo proved too challenging to maintain as you needed special Rivo pods.
Instead, Keurig discontinued the Rivo and created their K-Cafe and K-Latte machines.
The K-Cafe is more feature-rich than the K-Latte, offering the following upgrades
Essentially, the K-Cafe is designed to be a specialty beverage station.
The K-Latte mostly is a typical Keurig coffee maker with a "stronger coffee" button and a collapsible dock for the frother, which only has a single frothing mode for silky latte foam.
For comparison, the K-Cafe's frother has two additional modes for more aerated cappuccino foam and cold foam for iced beverages.
