<p>A cleaning brush assembly (20) for mounting on a rotatable shaft (18) of a swimming pool cleaner (10) for contacting the pool's surfaces to be cleaned is constructed from a number of annular and generally cylindrical segments or disks (22) of compressed cellulose sponge, or similar material, that expands when emersed in the water. The annular opening in the disks corresponds in size and shape to the cross-section of the shaft (18). The shaft (18) is marked to indicate the placement of the compressed disks (22). The expanded sponge assembly (20) provides an effective and efficient cleaning medium. <IMAGE></p> |
