Cleaning the system

Good morning to the round,
bitherto I have cleaned my Saeco Incanto regularly on the weekend.
I took out my brewing group and cleaned it with a brush in the water.

Now I have a Nivona 845.
And there it says in the operating instructions (analogously), when the display says "Clean system",
then according to the procedure as described the cleaning has to be done.
I mean that the machine says "to me when it's time for a cleaning?
I have the Nivona now well four weeks in regular -almost daily- use and so far it has not told me yet,
that it's dirty.
I have now yesterday gone through the cleaning program with one tablet
and afterwards additionally cleaned the brewing group under running water.

Thanks
