Hello I am very satisfied with the performance of the Roborock S7. However, I would also like to use cleaning agents for the floor care function. There is something like this on https://us.roborock.com/products/roborock-floor-cleaning-solution-for-all-robot-mops. Questions: a) When will Galaxus add the original cleaning agent to its range? b) Can I also use other cleaning agents and pour them directly into the water tank? Thank you very much for clarifying!
