The Aqua Products ABEXT Aquabot Xtreme In Ground Robotic Pool Cleaner is designed to clean and scrub residential in-ground pools of all sizes and surfaces. The focus is on the pool floor and the basin and wall where most debris settles. The Xtreme is equipped with dual PVC scrubbing brushes to help loosen stubborn dirt and debris. The G-Tooth drive track design helps protect the cleaner from excessive rubbing against the pool sides. The Xtreme is also compatible with the use of external timers.
