There is a 0.5 litre tank in the vacuum cleaner and approx. 2 litres at the station.
I have not yet tested the programming.

It has a water tank in the station. You can define how often it should wash the mob. E.g. every 10 minutes. And yes, it can be defined that it cleans everything twice

Good morning yes water tank is available has approx. 1.5 to 2 litres . 2 cycles are programmable. Kind regards
