    How to fix part of the pool not correctly cleaned by Zodiac CNX 20?
    • P

      If part of your pool is not being cleaned correctly by the Zodiac Vacuum Cleaner, first, repeat the immersion steps, trying different locations in the pool until you find the best spot. Also, check the cable positioning; ensure enough cable is unrolled into the pool and that the remaining cable is laid out by the pool side to avoid limiting the cleaner's movement. Lastly, a full or dirty filter can cause this issue, so be sure to clean it.

    Why Zodiac Vacuum Cleaner stopped climbing the pool walls?
    • C
      Charles CoffeyAug 27, 2025
      If your Zodiac Vacuum Cleaner no longer climbs pool walls like it used to, try the following: Clean the filter if it's full or dirty, and change it if it's clogged. If the tracks are slack or debris is preventing the bypass from operating, contact your retailer to replace the tracks or clean the bypass. If microscopic algae are present, perform shock chlorination and slightly reduce the pH, but do not leave the appliance in the water during shock treatment.
