R Nine One is a Rocket dual boiler with a fully saturated group, stainless-steel boilers — 1.9 litres for coffee, 3.6 for steam and hot water — and digital PID temperature control. It's built for either a small commercial venue or a home kitchen.
Pre- and post-infusion are shaped through a full pressure-profiling system: five preset programmes, or manual control via the Rocket Espresso paddle. An integrated shot timer and a touch display go along with the pour.
Water comes either from a direct mains connection or an internal tank, depending on installation. This is a machine for a home or a small venue, for someone who wants both the preset programmes and manual paddle control on hand.

Worth knowing
