It looks like the same problem I have with S7 MaxV Ultra, is going to be on this new S8 vacuum. I never refill the water tank on the vacuum on my own, because it auto fills it, but today, I was looking at the cashback offer, and cleaning it up for pictures, and there is brown build up or mold/mildew in the tank! So I have been cleaning my floors with dirty water! gross! I have found the same brown mildew in my clean water tank too, but Today is the first time I even looked at the vacuum's water tank. Please come out with a better solution to add to the Roborock products! It says you are only allowed to use Roborock cleaning solution, so now I don't know what to do!
