The Aquabot® Pool Rover Series 2 50 includes two fixed scrubbing brushes that agitate algae and film on surfaces before the intake ports for even better cleaning. Featuring a new, patented linear jet and low profile design, the Pool Rover 50 delivers a dramatic boost in suction power and water throughput while speeding up cleaning time. This means the Pool Rover 50 picks up even more dirt, debris and fine particulate down to 2 microns while cleaning faster! The Pool Rover 50 is designed for ALL above and in ground pool surfaces and shapes, and its rugged wheels are great for abrasive surfaces such as in gunite pools. Pool owners will especially appreciate the ultimate simplicity and out-of-the box ease-of-use of the Pool Rover 50 with one button plug and play operation, top access EZ-Clean filter bags, lightweight easy handling and extremely low maintenance.
