Every Dolphin Part, by Category
Each category lists every part of its kind with a filter for your robot. Open a part to see the models it fits, when to replace it and how.
Three Things to Know Before You Order
Filters wear first
Panels that stay brown or green after a rinse, bags with worn seams and torn net filters cut suction and stop the robot climbing. Replace them before anything else.
Match the part number
Many parts look alike. Each page lists the exact robots Maytronics confirms, and our pool experts check your model number before you buy.
Power supplies are replaced, not repaired
A supply that will not stay on with the cable disconnected is swapped under warranty without sending in the robot. Out of warranty, match the label's part number.
Not Sure Which Part Fits?
Send us the model name or a photo of the label and we confirm the part number before you order
Contact a Pool ExpertFrequently Asked Questions
Are these genuine Maytronics parts?
Yes. Every part in the catalog is the genuine Maytronics part with its Maytronics part number, and the parts we stock ship from Poolbots, an authorized Dolphin dealer, with the full manufacturer warranty. Genuine filters, brushes and power supplies are built for the robot's motors and tolerances; aftermarket copies often fit loosely, wear faster and can void the robot's warranty.
How do I find out which part fits my Dolphin?
Start with the model name on the label under the robot's handle (or on the power supply), then pick that model above and we open its parts list, with every part Maytronics confirms for it. Each part page also lists every robot it fits, and our pool experts will check the part number against your model before you order.
How often should filters, brushes and tracks be replaced?
Filters wear first: replace panels or bags that stay brown or green after a rinse, that have worn seams or torn mesh, usually every one to two seasons. Brushes and climbing rings go when the bristles flatten or the robot stops climbing. Tracks are replaced when they stretch, crack or slip on the wheels.
My power supply will not stay on. Can it be repaired?
Dolphin power supplies are replaced, not repaired. Unplug the blue cable first: if the supply still shuts itself off, the supply is the fault, not the robot, and under warranty Maytronics swaps it without the robot being sent in. Out of warranty, match the part number printed on its label to the power supplies above.
What if the part I need is not in your store?
Every one of the 241 parts has its own page even when we do not stock it, so you can confirm the exact part number and the robots it fits. Chat with us or call (888)-615-5728 with the part number and we will source it for you or point you to a Maytronics dealer that has it.
