Robotic swimming pool cleaners are convenient and automatic but they may sometimes get stuck in the corner of your above-ground pool. The Twister from Solar Sun Rings is a great pool cleaning accessory that keeps your pool cleaner on track. Compatible with all suction cleaners the Twister is easy to install. Twister continually changes the direction of the suction hose which drives the pool cleaner out of awkward corners to ensure a random thorough cleaning pattern. Once the Twister is connected to your hose line the pool cleaning accessory will rotate the hose by 350 degrees about 3 times per hour. This rate prevents the hoses from tangling. Twister needs to be fully submerged to function properly. While the Twister rotates the hose the hose line tugs the cleaner and keeps it moving for continuous movement throughout your pool. The included 30-degree angle adaptor is designed to fit between the cleaner and the section of hose that connects to the cleaner changing the direction that the cleaner is pointing.
