A pool skimmer is a device used to remove debris from the surface of a swimming pool. It typically consists of a floating or stationary unit that collects leaves, insects, and other floating particles. The skimmer works by creating a flow of water that draws debris into a basket or net, making it easy to clean and maintain the pool's water quality. In addition to manual skimmers, there are also automatic pool skimmers that operate independently. These devices can navigate the pool's surface, ensuring that it remains clean without requiring constant attention. Regular use of a pool skimmer helps keep the pool water clear and inviting for swimmers.
