Easy to set up and easy to use. Just attach your telepole and garden hose to the base of the unit and turn on the water. The resulting venturi lifts leaves and debris off the pool bottom and deposits them into the attached fine mesh bag, keeping them out of your pool and pump skimmer baskets. Great for easy Spring and Fall clean-up. Functions independently of your filter system and helps prevent filter clogging. Ideal for swimming pools surrounded by trees as the Leaf Gulper effectively removes large amounts of leaves and other debris from pool bottoms. Designed for use in above ground or in ground pools with concrete or vinyl surfaces. Includes extra-large mesh bag with draw string.
