I would like to install it in the bathroom. I don't see a problem with the fresh water supply, but what about the waste water? The siphon is about 70 cm from the floor, the robot is on the floor. Does it have a pump that transports the waste water into the siphon? And another question, if it wouldn't work: I like this one better than the Ultra. Can you run the Master without connections? Do they also have a tank?
