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. Read the specs on the product page.
