For those that have a robot cleaner, do you set the drains up or anything else different for the flow or water ? I have a valve that controls the sweep & main drain. I have it on 50 / 50 as I do currently use a suction vac. I am thinking the sweep intake also controls the flow to the skimmer ? With getting the robot vac I will be pulling the navigator & hose and closing the cover on the plug .
