The Bestway AquaPristine Pool 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. The power from the filter will suction dirt leaves and other particles into the removable and reusable debris bag. This vacuum set also features two interchangeable nozzle heads that connect to the included pole. One vacuum head has a brush to scrub stubborn grime from the bottom or sides of your pool while the other resembles a standard vacuum head for sucking up loose debris. It s like getting two pool cleaners in one! The included pole also breaks down into four sections for easy storage and transportation. The AquaPristine Pool Vacuum is compatible with above ground pools up to 15 ft. (4.57 m) in diameter and with filter pumps with flow rates of 530 gal./h (2 006 L/h) and above. This set also includes an adapter for use with skimmer style pumps.
