Hi! I encountered the same problem with my S5 Max in which no water is coming out. I already tried the suggested courses of actions I read from various discussions in this forum such as blowing of air holes, s*cking of water outlet, changing the mop cloth, putting on a wet mop cloth, poking the two small slots underneath the robot with a needle, disabling the carpet mode, and adjusting the water flow to the lowest level - unfortunately, none of these recommendations worked out! I NEVER used or mixed any detergent/cleaning solutions on my robot since day 1, only pure tap water. What seems to be the problem here? I've been using this for 4 months now and this is the only time it failed to mop my floor. This is not a cheap appliance and trust me, the money spent here is already something for a family affected by the pandemic. Please help, your kind feedback is highly appreciated.
