      If your Maytronics Swimming Pool Vacuum is moving in circles, it could be due to several reasons. First, check if the filter basket is clogged and clean it if necessary. Second, inspect the impeller-house or impeller-cover for any stuck debris and remove it. Also, make sure that the power supply is placed in a position so that the Pool Cleaner can freely reach all the pool area.

      If your Maytronics Swimming Pool Vacuum isn’t climbing the walls, start by cleaning the filter basket. Also, check the chemical levels of the water, as improper levels may allow algae growth, making the walls slippery. Adjust the levels and scrub the walls if necessary. Finally, inspect the impeller-house or impeller-cover for any debris and remove it.

      If your Maytronics Swimming Pool Vacuum only cleans part of the pool, ensure the power supply is positioned so that the cleaner can freely reach the entire pool area. Also, check that enough floating cable is released for the cleaner to operate correctly, allowing it to reach all areas of the pool. Clean the filter basket.
