Polaris Vac-Sweep 280 Frequently Asked Questions top Q: Why does my Polaris get stuck longer than 3 minutes on my ladder, including corners, or on other obstacles?
Your Polaris 280 cleaner needs to operate at a minimum number of wheel revolutions per minute. The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool keeping it submerged. Turn it so the single side wheel is up (make sure you hold on to the sweep hose so you will not get wet). Mark the single wheel or place a leaf or twig under the tire as a starting point; count the revolutions of the marked wheel for exactly one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off). If your wheel RPM are in the correct range, you will need to make sure your back-up valve is cycling. Hold the back up valve out of the water and watch the back up jet to make sure it turns on and turns off. This jet should be off longer than it is on. Finally, check your thrust jet located on the back of your cleaner; it should be in a straight back position. If all the above items check out okay, then it may be necessary to instal
