Optimal Pool Conditions for Your Robot

To begin with, the pool water temperature shouldn't be excessively low, as a low pool temperature can significantly hinder the robot's ability to climb. The water temperature should be maintained at a level higher than 35°C.

Checking Chemical Levels

Next, it is crucial to verify that the levels of your pool chemicals are within the recommended range.

Water chemical balance is essential for the optimal use of your Dolphin robotic pool cleaner!

If the pH levels are too high or too low, the robots climbing can be affected.

Ensure that your pool water is balanced and algae-free. If your Dolphin robotic pool cleaner tries to climb but slips on the wall, brush it manually with a broom brush until the deposits are removed. If necessary, rebalance your pool water.

Additionally, if your robot has a 'fast mode' or 'Floor Only' mode (only for models compatible with the MyDolphin/MyDolphin™ Plus app or with the power supply unit), verify that these modes have not been set by mistake. Ensure the cleaning cycle program is set to normal (long) mode and not 'fast' mode. For all these manipulations, we advise you to consult the user manual of your robot. You will need to indicate the model of your Dolphin robot.

Inspecting the Filters

• Check that the filters are not dirty or clogged (although they may look clean, small particles may dry on the material and clog it).
• It is recommended that the bag or cartridges be cleaned after each use, but deeper cleaning may be required.
• If you are using an ultra-fine (paper) filter, it should appear white. If it is brown or green, clean it with a hose set to the highest pressure. If it does not return white, it is likely due for replacement.
• If you are using an ultra-fine filter panel and have a fine filter panel available, swap to the fine filter. If it can climb, this indicates the ultra-fine filter needs to be replaced.
• Ensure the filter basket is properly installed, tightly fitted, and has no visible gaps. Also, ensure that the filter panels are properly clipped to the bracket.
• If the Dolphin still does not climb the walls, please test a 10-15-minute cycle by removing the filters. If the Dolphin climbs without the filters, you might need to replace them.
• Check our replacement spare parts page or find your local dealer here.

Debris in the Impeller

Make sure no debris is obstructing the impeller. Click here for instructions on how to clean your impeller.

1. First, unplug the power supply from the outlet. Use a Phillips screwdriver, not a power drill.
2. If you notice debris trapped in the impeller, open it, remove the debris, and reassemble the impeller.

Does your robot have an adjustable handle (click here)

The handles may be incorrectly adjusted if your Dolphin robotic pool cleaner does not move on the water line.

The handles on your Dolphin robotic pool cleaner can be adjusted to increase or decrease the speed at which it moves on the water line. A slower speed means that it travels a shorter distance but scrubs for longer, and a faster speed means it travels a greater distance but scrubs for less time.

For slow waterline cleaning (covers less surface area but cleans more intensively): Put one end of the handle in the second/third slot, and the other end of the handle in the second/third slot (pictured above on the left side)

For fast waterline cleaning (covers more surface area, but cleans less intensively): Put one end of the handle in the first slot, and the other end of the handle in the fourth slot (pictured above on the right side)

Ensure Sufficient Cable Length

If your robot doesn't have a handle or still cannot climb or clean the waterline, make sure it has enough cable to climb the wall—if there's not enough, the cable can pull the robot back!

Ensure the robot has enough cable slack to facilitate its climbing and maneuvering in the pool.

To determine if you have the appropriate amount of cable in the pool, measure the cable length that matches your pool's longest dimension.

It is important to remember not to use an excessive length of cable to avoid tangling issues.
