The KB90 is the ultimate evolution of the Linea PB form.

Designed specifically to increase speed of service in the highest volume cafes while easier for the barista thanks to an improved workflow.
La Marzocco has redesigned the portafilter system to improve workflow efficiency and to reduce the wrist strain of the user.
Efficiency can also be increased thanks to Steam Flush: after each extraction, a burst of steam from the grouphead is followed by a flush of hot water, keeping the machine clean even in the busiest rush hours.
This innovative function minimizes off flavored buildup, and increases the time between having to clean the group.
The KB90 allows for a new level of expression in machine design, the panels have been engineered so that virtually infinite customization combination can be created.
