Why isn't the EON 100/120d climbing walls?

For the Dolphin EON 100, work through these checks in order.

1. Step 1Check the app settings

   • Select the Maze scanning pattern so the robot starts climbing walls at the beginning of the cycle.
   • With Line-by-Line selected, the robot spends the first two-thirds of the cycle cleaning the floor. It climbs walls only in the final third.
   • Run a cycle using UltraClean mode with the Maze scanning pattern.

   The robot can climb only when its front faces the wall. If the rear reaches the wall first, it will not climb.

2. Step 2Clean the filter basket

   A clogged basket can weaken suction and reduce wall-climbing performance.

   • Take out the filter basket and use a hose to rinse it thoroughly.
   • Check the filter's color. A clean filter should look white.
   • Keep rinsing if you see brown or green discoloration.

   For replacement DebrisLock basket ultra-fine filter cartridges (99987101-ASSY) or a monoblock net filter basket (9998715-ASSY), contact Poolbots' pool experts by live chat or phone.

3. Step 3Look for obstructions

   • Examine the tracks and wheels. Carefully clear away any debris.
   • Inspect the impeller and its housing for hair, leaves, or other debris. Clean them as needed.

4. Step 4Update the app and robot software

   • Check that you have the latest version of the Maytronics One app. Install an app update if one is available.
   • If the app requests a robot software update, finish it before starting the next cleaning cycle.

   Older software can affect how the robot navigates and climbs walls.

5. Step 5Check the pool water

   Check your pool's chemistry, with particular attention to pH. Excess algae or unbalanced water can interfere with movement and wall climbing.
