The main difference is capacity and technology. The classic A400 fully automatic coffee machine delivers professional coffee quality for up to 120 cups a day. The new A400 raises that to 150 cups a day and adds a range of new technologies: New FoamMaster for barista-style foam, and an optional iQFlow™ for more consistent extraction. DualMilk, ActiveChill, and the Flavor Station bring a wider beverage offering across hot and iced drinks, and IndividualClean adds a usage-based smart cleaning routine that adapts to how the machine is actually used.
Both machines are positioned and built for reliable, everyday operation without specialist coffee expertise. Choose the classic A400 for professional everyday coffee at moderate volume. Choose the new A400 if you need higher daily capacity, a broader beverage range, or the premium, consistent quality of the latest New A Line technology.
