I have just bought a house and cleaned the pool. I am a novice in pool taking care of. I have a Polaris robot. My problem is that when I plug it in the pool the quick connection is not staying, it doesn't stick to it due to the pressure of the jet. There seems to be no problem with the plug itself, it doesn't seem to be broken at all. The Robot seems to be in pretty good shape.
Anyone would see where the problem could come from? Thanks in advance for your advices.
