The New Pool Blaster Battery Powered Leaf Vacuum* (Patent Pending) is completely self contained. It does not rely on garden hose pressure to get the job done. Instead, its "on-board" Motor, Transmission and Safety Clutch combine to lift leaves right off the pool floor and deposit them into its high capacity debris bag. At the heart of the Pool Blaster Leaf Vacuum is its unique Super-Suction Propeller. This wide bladed prop enables the Pool Blaster Leaf Vacuum to effortlessly pull leaves up and off the pool floor. And, while creating suction, the slowly rotating propeller continuously keeps debris, such as leaves, seeds and twigs, agitated and moving, which avoids blockages experienced with "Pressure Side" (garden hose) Leaf Vacuums. The Pool Blaster Leaf Vacuum features Water Tech's proprietary Safe-Blade System to assure worry-free operation.
