ABSTRACT:
A device that augments sidewall skimming of a swimming pool. The device is a substantially rectangular, hollow box with one end fitting within a sidewall skimmer and the other end protruding into the pool water. The device is made of a flexible, soft, foam-like material. The device is secured in the skimmer by inwardly deforming the end to be inserted and placing it in the skimmer where, upon release, its original shape is restored and a snug top and bottom friction fit is achieved. The sides of the device are in a loose fit within the skimmer. The device enhances sidewall skimming by channeling water along the sides of the device and into the skimmer, and by channeling water through its hollow internal cavity and into the skimmer.
