Abstract
A swimming pool vacuum cleaning apparatus having a number of pivoted, easily separable sections and provided with end bumpers. The end sections of the apparatus can readily be separated from the center sections by removal of hinge pins. The end sections can then be reversed to place an unworn portion of the bumper in a position exposed to rubbing and the apparatus reassembled. The pivoting feature of the sections allows conformance of the apparatus to uneven bottom surfaces and to the transitional surfaces between the bottom and sides and the bottom and ends of the pool. The apparatus can be conveniently increased in width by the addition of extra center sections and suction openings.
