The specifications table lists boiler capacity (1.80 l), power, dimensions and weight, but does NOT print the portafilter diameter — which is why this entry sits at the measured tier rather than manufacturer-verified, despite the Appartamento being an E61 machine.

Describes the Appartamento TCA as having a 'redesigned E61 brew group' (E61 groups take 58mm portafilters), but prints no portafilter diameter for the base Appartamento. This is the firsthand basis for the measured-tier 58mm figure — Rocket confirms the E61 group; the diameter follows from the E61 standard.
