My Dolphin robotic pool cleaner is not cleaning the pool properly or missing spots



If the robot is not cleaning the pool as it used to or is missing spots in the pool, we recommend verifying the following parameters:




Maintaining these levels is essential to preserve the robot's performance and longevity.


The weather, our own body chemistry, and additional factors can affect the chemical levels in the pool. Therefore, we recommend checking the chemical levels regularly by carrying out regular pool water tests. Your local Elite Dealer will be able to help you with this.


Check that the water temperature is between 6° - 35° Celsius/43° - 95° Fahrenheit.

If your robot struggles to climb, ensure the pool temperature is higher than 15°C/59°F, as low temperatures can make it difficult for the robot to climb.


Depending on the type of debris there is in the pool, this will help determine which filter type is most suitable for use.


If the debris is fine such as sand and dirt we recommend using ultra-fine filters. If your robot did not come with ultra-fine filters these can be purchased separately here and inserted into your filter basket. Click here to watch how to swap your fine filter panels to ultra-fine filter panels.



If the debris is large, such as tree foliage we recommend using Maytronics fine (net) filters.



If the debris is sticky it could be an accumulation of algae. In this case, we recommend contacting your local Elite Dealer for further analysis and chemical shock treatment.


If you complete a chemical shock, wait at least 24 hours after treatment before placing the robot back in the pool and check the chemical levels have returned to normal.


If there is a large amount of debris in the pool, it may be necessary to run multiple cycles in a row and to clean the filter after each cycle.

We recommend cleaning your filter(s) after each use. Remove the filter(s) from the robot and wash each panel (or bag) thoroughly with a water hose. Place the filter(s) back in robot. Click here to see how to clean your Dolphin filter basket.


The ultra-fine filter should be white-if it is brown or green, clean it with a pressure washer.


If it does not turn white you may need to replace it.


Confirm the filters are not clogged and that the robot is free from debris, as clogged filters can interfere with the suction process and prevent the Dolphin robot from picking up debris effectively.

Impeller

If you notice debris trapped in the impeller (located on the top of the cleaner), unplug the power supply before cleaning.

Open the impeller cover using a Phillips head screwdriver (not a power drill). Remove the debris (needle-nose pliers are best), then reassemble.


Rapid drain flap


If applicable to your robot, make sure that the rubber rapid drain flap on the back of the robot is securely installed.


Brushes


Ensure that the PVC brushes are fully intact, with no ears, or external damage. If they show signs of wear and tear, we recommend replacing the PVC brushes.


If the brush has white climbing rings, they should be white in colour and not flattened or damaged. If they show signs of wear and tear we recommend replacing the climbing rings.


Tracks


Ensure that the tracks are tightly fitted on the robot without damage or discoloration.


If the tracks are discolored or loose, we recommend replacing the tracks and verifying that the pool chemical levels are within our recommend usage range.


Finally, check your filter's non-return valve–the opening at the bottom of the filter–or the little black pouch attached to it and make sure it is free of debris.


Also check there is no debris in the in-take opening. Place the robot upside down and remove any obstructions.

It is important to note that our robots are not designed to clean steps, stairs, or ledges.


Our robots require submersion in at least 80cm of water to function properly.


If there is debris in the seam of a steep slope, we recommend brushing the debris from the seam onto a flat surface so that the robot will be able to reach the debris.

Make sure to put enough blue cable in the water to allow the cleaner to reach all areas in the pool.


It is important to make sure that the robot has a cable long enough to allow full coverage of your pool. You can measure the distance between the two farthest corners of the pool to get an understanding of the amount of blue cable needed. If your pool's length is over 30', make sure to use a robot with a cable length of 60'.


It is important to make sure that your robot's brush type is compatible with your pool coating.


If your pool has a tiled, concrete, or gunite coating, it is most compatible with a robot that comes with a PVC brush.


If your pool has a rough ceramics, fiberglass, or mosaic coating, it is most compatible with a robot that comes with a Combined brush (nylon should be removed before use).


If your pool has a smooth ceramic, stainless steel, or glass coating, it is most compatible with a robot that comes with a Wonder brush.


If the robot still isn’t cleaning the pool properly, please contact us, and our expert team will assist.
