I had a pole from a broken skimmer. Used a small pump from a smaller pool. Add pool hose to the end of the pump that sucks water in. I used tuck tape to tape the hose and the pump to the pole. Make sure there is a filter in the pump. Submerse the pump in the water prime it with the screw on top. Then plug it in. It works great. And you don't run out of power like the rechargeable vacuums.
Happy pool cleaning;)
