KB90

The KB90 is purpose-built for busy cafés that demand both efficiency and consistency. Its redesigned straight-in portafilter system streamlines workflow and significantly reduces barista wrist strain. The addition of Steam Flush automatically cleans the group after every extraction—releasing a burst of steam followed by hot water—helping maintain flavor clarity and extending the time between deep cleanings, even during peak rushes. With fully reimagined panel engineering, the KB90 also offers unprecedented flexibility in aesthetic customization, allowing cafés to create a machine that performs at the highest level and reflects their unique brand.

Linea KB90 Overview

Straight In Portafilters

La Marzocco revolutionizes workflow with its straight-in portafilter system, engineered to boost efficiency and minimize wrist strain. A quick release of the tab allows the portafilter to drop or be pushed smoothly into place, eliminating the twisting motion that can fatigue baristas during high-volume service.

Auto Steam Flush

After each extraction, a burst of steam from the steam boiler purges the brew path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative function minimizes coffee residue in the group, and reduces the number of times baristas need to back flush during service.

Drip Prediction (Optional)

With optional scales incorporated into the drip tray improve beverage consistency by stopping the extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot accuracy and ease of dialing in.
