Abstract: An underwater vane (10) attached to a special support bracket (13) which is clamp-mounted on a standard pool broom pole (24). The vane is bent to form two equal planes (11A & 11B) joined together at a central axis. The axis has pivot holes (19) from which the vane is transversely suspended over the pool broom pole. When the pool broom pole is pushed or pulled through the water, the vane is caused to tip by water pressure until one side and then the other touches the pole. The angle formed between the vane and the pole in either direction of motion causes the deflection of the pole and the attached cleaning device toward a surface being scrubbed.
