The differences that matter
The dimensional difference is substantial: Appartamento is narrower and deeper (27.4 x 43.95 cm), while Cube is wider and shallower (33.6 x 32.3 cm). Cube allows direct water line connection and uses a stainless steel boiler with a thermosiphon group, adding 7.7 kg in weight (27.7 kg total). Appartamento utilizes the traditional E61 group, offers a larger reservoir (2.5 l versus 1.8 l), and does not support plumb-in operation.
Which one to choose
Choose Appartamento if…
Rocket Espresso Appartamento suits users with limited width space (27.4 cm) who operate exclusively with an internal reservoir (2.5 l). Its E61 architecture without PID requires learning the cooling flush, sitting in an estimated price range of 1000–2200€.
Choose Cube if…
Sanremo Cube addresses the needs of users requiring a direct water line connection and operating in spaces with reduced depth (32.3 cm). The required investment in the estimated 2200–5000€ range provides a thermosiphon group with a stainless steel boiler and higher power draw (1500 W versus 1350 W).
