A swimming pool cleaning apparatus comprises a number of joined sections of tubing or pipe in a generally T-shaped configuration. The pipe is preferably PVC pipe. The preferred embodiment comprises an elongated hollow pipe section referred to herein as the head. The head is preferably about 28 inches in length, although lengths of about 20 inches to about 40 inches have been shown to be suitable as well. The PVC pipe used in the preferred embodiment is standard half-inch PVC pipe, but other size PVC may also be suitable. The head pipe has a plurality of aligned 1/16 inch diameter holes drilled through the pipe along its length. In the preferred embodiment, these holes are drilled at different angles relative to the longitudinal axis of the head. One or two of these holes are drilled to be perpendicular to the head axis while holes to either side of the perpendicular holes are drilled to have an angular offset of about 5° from hole to adjacent hole. This offset provides a more effective cleaning pattern.
