Ahh, this skimmer had an old fashioned 'wet neck'. So it had this fitting through the lid, that was designed to spray water and spin around.
It didn't work well or really at all.
But.. the bones were good. I attached the motor to the wetneck shaft, and the squeegees to the pvc pipes that sprayed water.
I would imagine for the DIY manual cleaner, a person could put a piece of 1/2" CPVC through the lid and mount the squeegee to that if gluing to the lid like the video is not an option.
