My Dolphin isn't cleaning the pool properly
If the robot is not cleaning the pool as it used to or it is missing spots in the pool, 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.
Check that the water temperature is between 43° - 95° Fahrenheit.
If your robot is struggling to climb, make sure the pool temperature is higher than 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, 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. Click here to visit 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.
It is important to clean the filter after each cleaning cycle to prevent the filters from getting clogged. Click here to see 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.
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. Click here to visit 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. Click here to visit 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. Click here to visit our Replacement Spare Parts page for more information.
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.
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.
