1 GROUP OR 2 GROUPSFOR COFFEE
Comparison of parallelism, pair, place and rack requirements.
The number of groups is one element of the system. Compare the same menu, command and peak scenario.

01QUICK VERDICT
One group saves space; two give parallelity if workflow is able to use it.

How the decision changes
Orders cross regularly
Two groups are useful if grinding, milk and giving do not become a new restriction.
An unknown future stream
First, measure the current process and confirm the engineering limitations.

There are discrepancies in the listingTop-level attributes report a 1.1 L water tank and 20 bar pressure, while the supplier specification describes a plumbed three-boiler platform with a commercial rotary pump. The title says double boiler, but the detailed supplier table says three boilers. The listing mixes commercial applications with home-enthusiast copy.

05frequently asked questions
Before the final choice
Two groups twice as fast as one?
They give the second extraction position, but the whole queue includes grinding, milk, assembly, dispensing and washing.
Is it worth taking two groups to grow?
Only if you have a demand plan, space and engineering, and unused width and power don't create value by themselves.
How to compare real models?
Compare groups, automation, boilers, food, water, sizes, service and test on the same menu.
Compare the process, not just the body
Peak scenario, team, coffee grinder, water and rack determine the result along with the machine.
