Rocket Espresso Milano - Cellini Evoluzione V2

I've got a Rocket HX (Cellini Evo v2). Have you ever seen innards of the boiler of say 5-years HX machine which wasn't descaled with so-called "boiler overfill" method (water probe connector is removed, so the boiler is filled \*fully\* with descaling solution)? If so, how does it look like?

Much bigger boiler, much better steam, e61, rotary pump => Rocket Cellini Evo v2 (it's HX).

ECM, La Marzocco, Profitec, Bezzera, Rocket, Faema and basically every E61 group head machine.

Rocket makes some great HX machines.

I’ve had Rocket HX machines for the past 14 years and never had a problem making milk-based drinks or entertaining. I think double boilers are overkill but to each their own. As commented below, a $20 smart plug solves your preheating problems. Who says the water reservoir doesn’t come out? Is that a thing? Mine does. Plumbing in would be preferred but my space isn’t big enough in the kitchen so my machine is off to the side on a coffee cart. Happy coffeeing.

would definitly look into young used machines, so many people get into this hobby and then stop because they think too much work involved. I'd look into a Rocket, ECM, Profitec, lelit etc... Minimum Heat exchanger boiler. (I have a Rocket with HX boiler, make only 4/5 cappucino's a day without any problem) and a decent grinder.

Rocket has finally shipped their fast prosumer models. Have a look. They stuffed a pid-controlled cassette into the brew head. Unless your side hustle is an espresso stand, HX will work.
