The Z5 monitors the usage of the machine and automatically makes the appropriate decisions and suggests actions. For example, once you make a milk product such as a cappuccino, it'll bring up a message after a few minutes reminding you that you should rinse the frother. Great, because we know milk grows bacteria after a few minutes. So, the frother is always in a clean condition.

When you open the grinder by-pass lid, the Z5 defaults into pre-ground mode automatically. This saves a couple of push button steps. It even detects if not enough ground coffee is being used.

When the rinsing button is pushed, the Z5 will also clean the frother if a milk product has been dispensed but not if the frother hasn't been used. This of course is also happening when the machine is being turned off.

You'll notice a slight delay before the Z5 will start foaming milk after pressing the cappuccino button. This is due to the single boiler issue. However it only takes about 5 seconds for the steam to kick-in and this is quiet impressive.

The Z5 even comes with a little elegant milk thermos cooler. It features double wall insulation. If this isn't enough you can select between frother attachments. One for short cups and one for large cups.
