Abstract
A vertically upright, elongated, flotable skimmer blade has an inboard end fitted within the overflow water return port of a swimming pool vertical side wall with the blade outboard end extending away from the pool side and angled upstream relative to the water circulating in the pool and diverted into the port. A suspension wand has one end frictionally coupled to a U-shaped strap fixed to the outboard end of the blade and a second end coupled to a weighted bag which rests on the side of the pool with the wand angled relative to the blades and with the wand upstream of the overflow water return port. This permits the blade to rise and fall with the water, allows floating blade angular orientation relative to the flow of water at the pool surface to be readily changed and permits the debris deflector to be stored easily with the wand folded against the blade during deflector removal and nonuse.
