The Vevor pool brush head is designed for cleaning inground and above-ground swimming pools with a wide 20-inch head for faster coverage. Its high-density nylon bristles provide strong scrubbing power while remaining gentle on pool surfaces such as tile, vinyl, and fiberglass. Detachable curved side brushes help reach corners, steps, and curved walls more effectively. The aluminum alloy connector fits most standard 1 1/4-inch pool poles for quick installation. Pole not included.
