The Bestway AquaCrawl Vacuum is simple to set up and easy to use to keep your pool water crystal clear. Simply attach it to your filter pump with one of the included adapters and start cleaning. Debris is sucked into a removable and reusable leaf bag. The two interchangeable conversion nozzles connect to the pole, one with a brush for stubborn grime and the other a standard pool vacuum head for sucking up loose debris. You get two pool cleaners in one! Recommended for pools up to 15ft/4.57m.
