A pool leaf catcher cover is a sort of ingenious solution to common problems in areas where lots of leaves fall. The fine-mesh material slips over your pool cover and holds leaves and other debris but not water. It is a beautiful sight when the leaves turn hues of red when the weather grows cold, but rotting leaves floating in a pool of water on your pool cover is not as pleasant. Letting leaves sit in that condition can stain pool covers and make cleanup later when the weather warms up far more difficult. Whenever you are ready, pull the pool leaf catcher cover off and dispose of the leaves, then reapply the pool leaf catcher cover if needed.
