The Swasher is a unique enhancement for a pressure-side pool cleaner and attaches securely to the tail sweep hose. The Swasher eliminates the two big annoyances of these cleaners: unwanted spray from the tail sweep hose, and frequent foam scrubber replacement. The innovative design has a unique diffuser ring that keeps the pool water in the pool, while actively rotating and cleaning the pool. No more pool sweep tail geysers spraying people, windows, or your landscape! The Swasher fins create rotational sweeping action to dislodge and brush more dirt and algae from all pool surfaces, including walls and waterline. Stop the manual scrubbing and let the SWASHER do the work for you. It is built with a durable and long-lasting polymer material that replaces the short-lived foam. **A wear ring is included to replace the worn ring on the sweep hose closest to the Swasher. The wear ring should not touch the Swasher or it will reduce the rotation. You may want to replace all the wear rings if they are worn to ensure maximum life of the sweep hose** The SWASHER is easy to install and stays firmly attached to any pressure side pool cleaner with 9/16” tail sweep hose diameter including: Polaris pool cleaner, Polaris 3900 Sport, P39, TR35P, 380, TR36P, 360, TR28P, 280, and 180; Pentair pool cleaners, and Zodiac pool cleaner models.
