The KB90 is the ultimate evolution of the Linea PB form, designed to optimize workflow for baristas by improving the ergonomics and features of the machine. The Straight-In Portafilter removes strain on baristas that cause repetitive stress injuries. Efficiency is also increased thanks to Steam Flush: after each extraction, a burst of steam purges the brew path and is followed by a flush of hot water, keeping the group heads clean even during the busiest hours.
