Need help. I've had Poolvergnuegen second gen pool cleaner for about a year now. All great until a few months ago. I have it set to clean 4 hours daily. Almost every single day the mechanism inside the cleaner gets stuck and stops working. I keep having to open the cleaner up, and make sure the internal little windmill plastic pieces are lined up well in their channel. Then I close it up and it would work for another day or two until it stops working again.
At first I thought it was debris, but there really isn't anything inside to cause it to stop. I think it is the little plastic windmill inside that sometimes moves slightly out of place and cause it to get stuck.
