Battery-operated, handheld vac attaches to the end of a telescoping pole (not included) to vac-up small leaves, debris, sand and algae you might spot in your pool or spa water. No need to connect to your pool's filtration system, since it has its own internal vac motor. Large-capacity filter bag is easily cleaned and re-used. Runs up to three hours on one set of five "D" Batteries (not included).
