I took the vacuum head off my suction vac and used waterproof tape to tape my light extension pole (goes to leaf skimmer) to hose and I use the hose at an angle to go around the edges and pick up sand that seems to lie where my cove starts. My yard around the pools is sand right now and my three boys get a lot of it in the pool. The Vacuum brush does not seem to want to pick it up against the wall but just the hose does great. Attaching it to the aluminum pipe makes it easy to go around the pool and pick up all the sand.
