Question 1

My Dolphin doesn't climb the walls or move sideways on walls

Accepted Answer

Optimal Pool Conditions for Your Robot The robot should be used in water temperatures of 6°C - 35°C for optimal results. A low pool temperature can significantly hinder the robot's ability to climb. The water temperature should be maintained at a level higher than 15°C. Checking Chemical Levels Next, verify that the pool chemicals are within the recommended range. If the pH levels are too high or too low, this can affect the robot's climbing ability. 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. Inspecting the Filters It is imperative to check the filters. If you are using the Ultra-Fine (paper) filter, it should appear white. If the filter is brown or green, clean it with a garden hose set to the highest pressure. If the filter does not return to a white state– it is likely due to be replaced. For further details, please visit our Replacement Spare Parts page or a local dealer near you If you are using the Ultra-Fine filters, operate the robot with the Net Filters instead. If the robot is able to climb, this serves as an indication that the Ultra-Fine filters require replacement. Debris in the Impeller Make sure there is no debris obstructing the impeller. For instructions on how to clean your impeller, . First, unplug the power supply from the outlet. Use a Phillips screwdriver, not a power drill. If you notice debris trapped in the impeller, open it, remove the debris, and reassemble the impeller. Does your robot have an adjustable handle? Make sure the handle is aligned diagonally to help the robot climb. 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) Sufficient Cable Length Ensure the robot has sufficient cable to allow it to climb the wall – the cable can pull the robot back if there is not enough of it. 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. Brush Type It’s important to use the correct brush based on your Dolphin model, the surface type and slopes of your pool. PVC brushes are standard and work well for most pool floors. Combined brushes (PVC with foam climbing rings) help the robot climb and grip better—if your robot has climbing rings, don’t remove them! They’re essential for performance and should be replaced when worn. Wonder Brush is the ideal choice for ultra-smooth or slippery surfaces like stainless steel or polished mosaic tile. If your robot struggles to climb walls or stay attached to the pool surface, switching to a combined brush might help. But hold up—contact our Customer Care Support first to make sure your model is compatible with that switch.

Question 2

Why doesn't my cordless robot respond to the App while underwater?

Accepted Answer

Our cordless models, the EON™ and Liberty 400/600, do not remain connected to Wi-Fi or Bluetooth while submerged and operating in the water. After removing the robot from the water, if it was connected before, the Wi-Fi connection between the robot and the app will automatically reestablish. To use the Maytronics One app, connect to the robot via Wi-Fi, configure your desired cleaning mode or weekly schedule (UltraRun™ Mode/Eco Mode), and then place the robot in the pool to begin the cycle. Once the robot is in the pool, it will run the selected program independently. Our corded units allow for continuous Wi-Fi connectivity, as the connection is maintained through the power supply, which remains outside the water. Note- The Liberty 400 pairs via Bluetooth only to the MyDolphin Plus app.

Question 8

The Skimmi is in a sunny location, but it isn't charging

Accepted Answer

This can occur when the battery is full so that the skimmer runs on solar power instead of battery. When the sunlight becomes weaker, the battery will start to power the skimmer again and will continue charging. Ensure the Skimmi is exposed to direct sunlight to let the battery recharge. Cold weather and cloudy skies may impact the charging ability. If the SKIMMI won’t charge, please open the app and note the charging strength. If the charging strength is below 5 Watts, please check for possible limescale residue accumulation on top of the solar panel. In such a case, please gently clean the residue off using diluted citric acid or vinegar. If the charging strength is above 5 Watts, but the SKIMMI won't accumulate charge, it may indicate a faulty battery. Important: The robot is a solar-powered model. Sufficient solar power and direct sunlight are required for proper charging and operation.

Question 9

The Skimmi movement is jerky and/or making noise

Accepted Answer

This can happen if the water is full of debris or if there is very strong wind, making it difficult for the Skimmi to navigate properly. Try the following troubleshooting steps: In the app turn "Smart Detect" to OFF. In the "Smart Detect" function, select a lower water quality or switch the function OFF. Turn "Smart Detect" to OFF. Empty the filter tray and wash with a stream of water.

Question 10

The front paddlewheel is jammed on my Skimmi - How do I clean it?

Accepted Answer

Here are the steps to follow: Make sure the Skimmi is turned off and remove it from the pool. Remove any debris from the paddlewheel. Empty the filter tray and rinse it thoroughly to remove any remaining debris. If this continues to happen even after completing the troubleshooting steps, open the app and set 'Wheels Unblock' to 'Forced'. Please note that this option increases the skimmer's power consumption, which can potentially reduce the overall cleaning time. However, it ensures the wheels can move freely. Once there is less debris in the pool, change the setting back to Auto.

Question 11

The Skimmi often stands still, and cleaning time is reduced

Accepted Answer

If you often find the Skimmi standing still, and the cleaning time is less than usual, try the following steps: In the MyDolphinSkimmi app, reduce the length of Day Cleaning and extend the Day Pauses in 'Device Settings'. Turn energy-intensive functions off (i.e., Debris Washing = OFF, Speed = Low, Wheels Unblock = OFF) Turn on 'Smart Solar Recharge' in the MyDolphin Skimmi app. Set the 'Start Delay' to at least 1-2 hours. Keep the solar panel clean. Empty the filter tray more often.

Question 12

My Dolphin's filter is full - How do I clean it?

Question 13

My Dolphin isn't cleaning the pool properly

Accepted Answer

If the robot is not cleaning the pool as it used to or is missing spots, we recommend verifying the following parameters. Check that the chemical levels meet the following parameters: Alkalinity: 80-120 ppm pH: 7.2-7.6 Calcium Hardness: 150-250 ppm Chlorine: 1.0-3.0 ppm Cyanuric Acid: 30-50 ppm Algaecide: 30-50 ppm It is essential to maintain these levels for the best cleaning results and to preserve the robot's longevity. The weather, our body chemistry, and additional factors can affect the chemical levels in the pool, therefore we recommend checking the chemical levels regularly. to shop our pool chemicals Check that the water temperature is between 43° - 95° Fahrenheit. If your robot struggles to climb, ensure the pool temperature is higher than 59°F, as low temperatures can make it difficult for the robot to climb. If there is a specific area in your pool that the robot is missing, we recommend putting the robot in that area from the start of the cycle. If the robot is getting stuck in the deep end of the pool, it may be possible to upgrade the back brush on your robot to a Combined Brush or Wonder Brush. Please contact us contact us to verify if this solution will be suitable for your robot model. What kind of debris is in the pool? Depending on the type of debris there is in the pool, will help determine which filter type is most suitable for use. If the debris is fine debris, such as sand and dirt, we recommend using ultra-fine filters. If your robot model did not come with ultra-fine filters, they can be purchased separately. Our Replacement Spare Parts page for more information If the debris is large debris such as tree foliage, we recommend using our fine (net) filters. If the debris is sticky, algae-like debris, we recommend inquiring with your pool technician for further analysis and action. If you complete a chemical shock, wait at least 24 hours after the treatment, before placing the robot back in the pool and verify that the chemical levels have returned to normal. If there is a large amount of debris in the pool, we recommend running multiple cycles in a row and cleaning the filter after each cycle. How does the robot filter look? Is it quite full? Could it be clogged? It is important to clean the filter after each cleaning cycle to prevent the filters from getting clogged. How to clean the filters We recommend using fine filter panels for large debris such as leaves and bugs, and ultra-fine filter panels for tiny debris such as dust, dirt, and sand. Verify that 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 robot from picking up debris effectively. If the filters no longer wash white or the debris is stuck on the filter, we recommend replacing the filter panels. If you wish to purchase replacement filters, our Spare Parts page or reach out to your local Dolphin dealer. Let's make sure there's no debris hiding elsewhere in the robot. Impeller How to clean the impeller First, unplug the power supply from the outlet. Use a Phillips screwdriver, not a power drill. If you notice debris trapped in the impeller, open it, remove the debris, and reassemble the impeller. 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. 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 Please ensure that the PVC brushes are fully intact, with no tears, or external damage. If they show signs of wear and tear, we recommend replacing the PVC brushes. Our Replacement Spare Parts page for more information If the brush has white climbing rings, they should be white in color, and not flattened or damaged. If they show signs of wear and tear, we recommend replacing the climbing rings. Our Replacement Spare Parts page for more information Tracks Please 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 recommended usage range. Our Replacement Spare Parts page for more information Why isn't the robot cleaning the debris on the steps/ledge/tanning shelf? It is important to note that our robots are not designed to clean steps, stairs, or ledges. We recommend brushing the debris from the steps onto to the floor of the pool so that the robot can clean the debris. Our robots require submersion in at least 35” 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. Important tips! 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 PVC, concrete tile, concrete, or gunite coating, it is most compatible with a robot that comes with a PVC brush. If your pool has a PVC, 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.
