A pool cleaner is a device designed to maintain the cleanliness of swimming pools by removing dirt, debris, and algae. These cleaners can be manual or automatic, with automatic models often using suction, pressure, or robotic technology to navigate the pool and clean its surfaces efficiently. Using a pool cleaner helps to ensure that the water remains clear and safe for swimming. Regular cleaning prevents the buildup of harmful bacteria and keeps the pool looking inviting. Many pool cleaners are equipped with filters to capture small particles, making them an essential tool for pool maintenance.
