Pro-Fondi is a patented, electrical device by Ambrodesign that speeds up the extraction of coffee grounds and optimises professional machine filter cleaning with the action of three rotating blades. Designed to be installed next to the espresso machine, when the filter is inserted, the engine starts rotating. Two blades clean the inside of the filter, adapting to different sizes and shapes. The third blade cleans the coffee grounds from the edges. When grounds are not properly removed, it can cause the imperfect closure of the brewing chamber with subsequent leakage and coffee granules ending in the cup, which alters the taste and quality of espresso.
