  • Single-tap efficiency: With one press, you can reproduce your espresso recipe, saving time when serving multiple orders back-to-back.

  • Compact layout: The S200 measures 27.6 inches long, while the S300 extends to 37 inches, both built to sit comfortably on narrow counters.

  • Better customer connection: The lowered height keeps face-to-face interaction possible, perfect for open-bar café setups.

  • Functional comfort: All switches, wands, and displays are easy to reach, helping reduce strain for baristas during long shifts.

Steam wand performance, hot-water options, and accessories

 

  • Cool-touch wands: Ambidextrous steam arms stay cool, even under long use, letting baristas adjust milk texture safely.

Pros:

  • Volumetric control for quick shots: Let baristas save shot profiles for faster workflow during rush hours.

  • Multi-boiler setup: Enables simultaneous brewing and steaming without waiting for recovery time.

  • Compact, low-profile design: Takes up less space (27.6” to 37” width options), perfect for tight counters and open-bar layouts.

    • Solution: Start with pre-set programs and adjust one parameter at a time to build confidence before custom programming.

  • Heavier build: At 152 to 225 lbs, moving or repositioning takes effort.

    • Solution: Set up the unit in a fixed, well-ventilated area from the start to avoid future movement needs.
