After spending some time watching videos regarding the new Roborock "DYAD PRO", I still have some questions.
According to what I read on the manual & online, it says you can use any cleaning solution.
Yes, it does say to use the recommended "Roborock Floor Cleaning Solution", but it fails to say whether the solution needs to be diluted as mentioned on the instructions or leave it like it is (do not dilute).
You can add cleaning solution into the cleaning solution tank directly. Dyad Pro will automatically dispense the cleaning solution during cleaning. There's no need to dilute it.
However, the cleaning solution should be diluted when being added to the clean water tank. Diluting ratio is 1:300, one part of cleaning solution and 300 parts of water.
