Pool skimmers are designed to help get rid your pool of leaves and other debris to keep the water in your pool clean for swimming. Pool skimmers are available in aluminum and plastic models. Although aluminum skimmers are more expensive than plastic ones, a pool skimmer made of aluminum will last longer and work more efficiently than a plastic model. Some pool skimmers are available with removable mesh which can be replaced if the mesh gets torn or ripped. When not in use, pool skimmers should be stored on wall hangers or wall mounts, and kept off the pool deck for safety reasons.
