Automated pool cleaners perform vacuuming on pool surface automatically while the pool system runs. Automated cleaners like the Polaris use the pressure created by water returning to the pool from the filter and pump system to move. The high pressure water moves through the Polaris inner body and is expelled out a thrust jet nozzle located on the back of the Polaris body. The force of the water moving out of the nozzle pushes the Polaris forward across pool surfaces. Adjusting the direction the thrust jet points influences the way the Polaris moves underwater.
Cut power to the pool system and any booster pumps connected to the pool. Most pool systems have a central switch located by the pool that turns off all pool systems. Shutting off power to the pool stops water flow, making the thrust jet accessible.
Carefully lift the Polaris out of the water by the hose. Set the cleaner down and examine the back section of the Polaris -- the section with the hose sweep or "tail."
Move the thrust jet nozzle to point at the seven o'clock position. This is the recommended setting for the cleaner and causes the Polaris to move to the left slowly in the pool and stay firmly seated on the ground. Adjusting the jet further customizes the way the Polaris moves in the water. Pointing the jet higher causes the Polaris to climb easier, pointing the jet lower increases how firmly the Polaris hugs the ground, moving the jet left moves the Polaris left, and moving the jet right moves the Polaris to the right.
Lower the Polaris by the hose into the pool. Turn on the pool and observe how the Polaris moves in the pool. Adjust the jet and retest until the desired movement is reached.
