Works better than any other robotic cleaner I’ve owned.
This bad boy vacuums like crazy. Climbs the walls and stairs like nobody’s business. Highly recommended
Used this 5 times in a couple of months. It worked but small collection bins don't pick up reasonable size leaves, etc. Then died just after the three month return warranty expired! So I'm out $2K. Horrible poorly written instructions don't explain how the control unit works. Do not buy!!!
Our pool is 35' wide by 75' long. We do drop it in every other night and it does a great job keeping up.
The company has been so helpful and it’s a great product for our neighborhood pool!
No, we never charge a restocking fee ever! We know a robotic pool cleaner is a big investment, which is why we offer Free 30-Day Trials on all robotic pool cleaners!

If your Dolphin powers on but does not move, try checking the tracks for any debris or obstructions. Also, check the drive motor and impeller for any damage or wear. If you are still having issues, contact Maytronics customer support for further assistance.
If your Dolphin's power supply is not turning on, check to make sure it is properly plugged in and that the outlet it is plugged into is working. If the power supply is still not turning on, contact Maytronics customer support for further assistance.
If your Dolphin W20 is not cleaning the pool properly, try checking the filter bag for any debris or blockages. Also, check the brushes and tracks for any damage or wear. If you are still having issues, contact Maytronics customer support for further assistance.
The handles on your Dolphin are for lifting and carrying the unit, while the floats are designed to help your Dolphin navigate around the pool and maintain proper buoyancy.
To remove any debris or obstructions from your Dolphin's tracks, turn off the power supply and carefully remove the tracks from the unit. Use a soft brush or cloth to clean the tracks and remove any debris. Once clean, reattach the tracks to the unit.
If the power unit LED indication is off even when the charger is connected, please try the following steps: 1) Unplug the power supply from the outlet and wait for 10 seconds. 2) Plug the power supply back in and check if the LED indication turns on. 3) If the LED indication still does not turn on, contact Maytronics customer support for further assistance.
