Dolphin 2 X 2 Robotic XL Commercial Cleaner w/ Caddy & Remote. CLEANS OLYMPIC SIZED POOLS! Like all Dolphin™ cleaners, the 2x2 is a computer-controlled robotic cleaner that vacuums and scrubs any shape pool and maneuvers around ladders, drains, and stairs. The unit has its own filtration system so it will never clog up your pool's pump or filter. The Dolphin™ 2x2 will operate in automatic or manual mode. In the automatic mode the unit memorizes the pool's dimensions and computes a precise path to clean your entire pool, including the walls. The unit will automatically shut itself off after 16 hours. In the manual phase, the remote control unit allows the operator to guide the 2x2 to spot clean areas that need extra attention. It also allows the operator to program the unit for variable data such as pool length, pool shape, cycle time and wall or floor cleaning. Since the Dolphin™ 2x2 operates on 24 volts, it is completely safe and economical to run. Its powerful motor can filter up to 6,500 gallons per hour and the unit is backed by a 2-Year Warranty. The 2x2 comes complete with 200-feet of cord, caddy, 2 filter bags, and a wireless remote control unit.
