Pressure-side cleaners are devices used to clean swimming pools by utilizing the force of water. They connect to the pool's filtration system and move around the pool, scrubbing surfaces and collecting debris. These cleaners are effective for removing dirt, leaves, and algae, helping to maintain a clean swimming environment. These cleaners typically operate using a combination of suction and water pressure. They can be powered by the pool's pump or have their own motor. Popular types include automatic pool cleaners and robotic pool cleaners, each designed to simplify pool maintenance and enhance water clarity.
