Pressure-side cleaners are devices used for cleaning swimming pools. They connect to the pool's filtration system and use the water pressure to move around the pool, collecting dirt and debris. These cleaners can navigate various surfaces, including tiles and vinyl, making them effective for maintaining pool cleanliness. These cleaners typically have a series of wheels and brushes that help scrub the pool floor and walls. They are powered by the pool's pump, which means they do not require a separate power source. Regular use of pressure-side cleaners can help keep pools clear of leaves, dirt, and algae, ensuring a pleasant swimming experience.
