Vibiemme Domobar espresso machines comprise two sizes: a Junior Domobar, and a "Super" Domobar. The Vibiemme Domobar espresso machines also come with two boiler configurations: either a single boiler system (with a heat exchanger for steam), or a two-boiler system (one for espresso and one for steam). Finally, the Vibiemme Domobar espresso machines can either be standalone (with an internal water tank) or plumbed (connected to a water supply). All Vibiemme Domobar espresso machines have a classic heavy-duty E61 grouphead, with hot water cycling through the head to keep it hot.
The Vibiemme Domobar Junior (Junior DB) has a compact footprint with two boilers. The Vibiemme Domobar Super Double Boiler (Super DB) is a full-sized machine with two boilers. The Vibiemme Super DB can be connected to a water line, or not. The Vibiemme Domobar Junior HX has the same footprint and features as the Vibiemme Domobar Junior DB, except that it has a single boiler. Both Vibiemme Domobar Juniors (the DB and the HX), and the Vibiemme Domobar Super DB are semiautomatic machines - espresso extraction is turned on and off by the barista.
The Vibiemme Domobar Super HX espresso machines all have the same footprint as the Vibiemme Domobar Super DB espresso machine, but the Domobar Super HX espresso machines have a single boiler. The Super HX espresso machines come as either semiautomatic machines (the "Manual" models), or as fully automatic machines (the "Electronic Auto" models). The "Electronic Auto" Super HX espresso machines allow 4 dosage settings, and have a manual override that allow "Manual" operation.
The Vibiemme Domobar Super HX Electronic Auto (fully automatic) espresso machine can be ordered with a full stainless body in shiny silver, or can be ordered in black (it is the same stainless body, but painted black).
The Vibiemme Domobar Super HX Manual espresso machine (the semiautomatic model) comes only in the stainless finish (i.e., not in black), but can be ordered to connect to the building plumbing, or not. These are slightly different models.
