The Krups Automatic Foaming Attachment, makes foaming for cappuccinos a snap. Pour milk into included container and connect to the espresso machine's steam wand. Turn a dial to change the foam (less for lattes, more foam for cappuccinos) and start the steam. The milk is siphoned and foamed directly into your cup.
You couldn't ask for an easier cappuccino. Fits all Krups models beginning with XP40, XP20 and XP72.
