Aqua Vac, the company whose pool cleaners were used at the past five Olympic Games, is proud to offer the most advanced portable pool cleaner made for those who insist upon the very best. TigerShark2 comes complete with all of the standard TigerShark features but with a preset 7 hour cleaning cycle and and optional remote control to maneuver around the pool bottom with ease or spot clean whenever a full cleaning cycle is not needed. Tigershark2 calculates the size of the pool and programs itself into the most time and energy efficient pattern for a spotless pool. Tigershark's powerful on-board pump sucks up dirt and debris while roving the bottom, walls, inclines and steps for a pool that sparkles rim to rim! Tigershark2 is the first portable robot to feature an easy clean cartridge filter. Simply rinse and clean with a garden hose. This Tigershark is truly the ruler of the realm!
