Abstract: A portable swimming pool skimmer with a movable friction fit adjustable support holder. The friction fit support permits the skimmer to be adjusted up or down by sliding in a friction tube. The skimmer has a debris director to direct debris from along the pool side into the skimmer opening. The portable skimmer is used to save water by periodically adjusting the level of the skimmer by sliding along the holder so that the water level in the swimming pool remains in the skimmer opening so water can readily flow into the skimmer housing.
