This powerful cleaner features the same technology as its in-ground cousin, the Baracuda G3™. With only one moving part, it will thoroughly clean your above-ground pool of debris, twigs, leaves, and even pebbles. Since there is only one moving part, there is less maintenance on Ranger™ than other cleaners. The patented "Easy Access System" lets you remove the "flapper valve", service it yourself, and replace it right at your home. You can install the unit in minutes without any tools or special fittings. Since it runs off of your pool's pump and filter, Ranger™ cleans automatically anytime that your pump is operating.
