The R58 is Rockets first single group double boiler espresso machine.
What we like about it is that it merges the old school look of the E-61 group head with excellent temperature management. It has a plug in Serial port that is used to change the temperature and other settings. I used to think this was a bad idea plugging something in to change something but this keeps the machine looking true to its lineage ( see what we did there:)
This model comes standard with a rotary vane pump which is extremely quiet, it produces a small hum while you make espresso instead of the vibratory pump's brrrrrrrrrrrrrrrrrr sound.
Having two boilers is really helpful when making consistent coffee's. If you have ever tried to manage the temperature on a HX machine you will know what I am talking about.
Steaming on these machines is also quite easy as you can use bigger jugs and steam more milk at once because you have a dedicated steam boiler.
It can be used either with the built in water reservoir or switched to external plumbing.
