A pool brush is a cleaning tool specifically designed for maintaining swimming pools. It typically features a long handle and a brush head with bristles that can effectively scrub the walls and floor of the pool. Pool brushes help remove dirt, algae, and debris, ensuring the water remains clean and clear. These brushes come in various shapes and sizes, including curved and straight designs, to reach different areas of the pool. Many pool owners use them in conjunction with other cleaning equipment, such as pool vacuums and skimmers, to keep their pools in optimal condition.
