With its concentrated velocity of suction, the Spot-Vac captures all debris with which it comes in contact! Unlike conventional vac heads which disperse leaves, causing them to float away from the area being vacuumed, the Spot-Vac will not create clouds when removing algae, mud, DE powder or sand. Also, the innovative V-notch design on the nozzle prevents the Spot-Vac from sticking to the bottom of the pool.
