Suction-side cleaners are devices used to clean swimming pools by utilizing the suction created by the pool's filtration system. They attach to the pool's skimmer or dedicated suction line, drawing in water and debris as they move around the pool's surface. This process helps to remove dirt, leaves, and other particles, keeping the pool clean and clear. These cleaners are typically easy to operate and require minimal maintenance. They come in various designs and sizes to suit different pool shapes and types. Regular use of suction-side cleaners can enhance the efficiency of the pool filtration system and reduce the need for manual cleaning.
