Hi, I have been using S5 Max for over a year, however some months ago I start to notice a problem whereby the mopping doesnt work as the water isnt used at all. I had searched this forum and found the method of pushing air into the left intake holes and pulling the outlet holes of the water tank, I had done it before and it only works sometimes. End up each time I start the roborock I have to monitor it for at least 5-10mins to see if it is mopping, and if it doesnt then I have to pause the roborock to take out the water tank to blow the intake holes. Sometimes I have to do it 2-3 times before finally it starts mopping again properly.
I have never used detergent in the water tank, I always use filtered tap water, and I have also always emptied the tank after finish using. Yet this problem randomly occurs and I cant seem to find a proper and lasting solution. Please assist.
