Rocket R Nine One User Guide & Cleaning

The R Nine One combines a fully saturated group, dual stainless boilers (1.9 L brew, 3.6 L service) and a volumetric gear pump with five pressure profiles plus a semi-automatic profile. It suits serious home baristas and small boutique venues. These steps follow Rocket’s R Nine One user manual.

Which models this covers: One model: the R Nine One pressure-profiling dual boiler.

Before first use: water and start-up

Run the machine from the tank (fresh filtered water) or from mains water. Plumbing in should be done by a qualified technician – we can install it.
Switch on and let the machine reach temperature; the touch display shows when it is ready.
Run water through the group and open the steam valve briefly before your first shot.
Use the display to set the auto on/off times and your preferences, following Rocket’s manual.

Making espresso and choosing a pressure profile

Pick one of the five preset pressure profiles on the display, or use the semi-automatic profile and control pressure yourself with the group paddle.
Flush, dose, tamp and lock in, then start the shot.
Start with grind size when dialling in, then try different profiles to change body and sweetness.
Coffee volumes can be programmed so each shot is consistent.

Steaming milk and hot water

Purge the wand, texture with the tip just under the surface and lower it to heat. Close the valve before lifting the jug away.
Wipe and purge the wand after every use.
Hot water is mixed through a tempering valve – still take care, it is hot.

Daily cleaning (2 minutes)

With the machine hot, take the coffee basket out of the portafilter and fit the blind filter (the basket with no holes) supplied with your machine.
Lock the portafilter into the group and run the pump for about 10 seconds, then stop. Water and coffee oils flow back out through the group into the drip tray. Repeat 4–5 times until the water runs clear. This is a water-only backflush – no cleaner needed day to day.
Brush the shower screen and group gasket with a group head brush and wipe away any visible coffee, without taking parts apart.
Rinse the portafilter and baskets in warm water and wipe them dry.
Wipe the steam wand with a damp cloth straight after each use and give it a short purge to clear milk from the tip.
Empty and rinse the drip tray before it gets full, and keep the water tank clean and filled with fresh water.

Every 2–3 weeks: cleaner backflush

For home use, a backflush with espresso machine cleaner every 2–3 weeks keeps the group fresh. Rinse thoroughly with water afterwards so no cleaner is left in the group. In a café or busy office, ask us for a cleaning routine that suits your volume.

Heat the machine up fully and brush the shower screen and gasket.
Fit the blind filter and add a small scoop (about 3–5 g, or the amount on the pack) of espresso machine cleaner such as Cafetto Espresso Cleaner or Cafetto EVO.
Lock the portafilter in and run the pump for about 10 seconds, then stop and let the cleaner soak for 10–20 seconds. Repeat several times.
Remove the portafilter, rinse the blind filter and portafilter, then backflush again with water only until no cleaner foam or smell remains.
Run some fresh water through the group without the portafilter, refit your normal basket and pull one shot to discard.
While the cleaner is out, you can soak the metal portafilter head and baskets (not the handle) in hot water with a little cleaner for 10 minutes, then rinse well.

Water and servicing

Descaling: leave this to us. Your machine should only be descaled by a qualified technician as part of its service. Call 1300 357 575 to book.
Prevent scale instead: always fill the tank with fresh, filtered water. Don’t use distilled water – the machine needs some minerals for its water-level sensors to work.
Book a service every 12 months for home use, or every 6 months for cafés and busy commercial sites, so seals, gaskets and valves are checked before they wear.
