Abstract: A leaf skimmer for swimming pools or other reservoirs comprises a base to be mounted over a weir opening, a convexly curved front wall, and an opening, the skimmer capable of being mined to fact one way or the opposite way. It is provided with an inlet fitting which also may be turned to face one way or the other to direct a circulation of the water around the pool and carry leaves and other debris into the skimmer, the pool pump drawing water into the skimmer and pumping it back into the pool via the inlet fitting. The skimmer has a weir plate and non-return flap which may be inserted in the skimmer opening and adjusted to the water level, whichever way around the skimmer is mounted. A separator is provided to separate leaves which have been skimmed into a leaf trap.
