Support answer

How do I register my Dolphin's warranty?

Short answer: Register your Dolphin through Maytronics' online portal using your robot's serial number and proof of purchase.

Tools: Robot's 10-character serial number, Proof of purchase

Based on Maytronics support, updated 2025-11-24, rewritten by Poolbots' pool experts. Applies to 61 models.

The answer

What to know.

Use the Maytronics registration portal at warranty details to register your Dolphin and submit a rebate request.

Have your robot's serial number and proof of purchase ready before you start.

Find your serial number

Your Dolphin's serial number has 10 characters. You can find it in any of these locations:

  • The white label on the outside of the box.
  • Your warranty card.
  • The white barcode label on the Dolphin's inside casing.

Register your Dolphin

  1. Step 1Open the registration portal

    Visit warranty details.

  2. Step 2Enter the serial number

    Type your robot's serial number in the first field. For help finding it, select the “i” icon beside “Where do I find my robot’s serial number?”.

  3. Step 3Choose your previous cleaning method

    Select how you cleaned your pool before getting your Dolphin. Then select “Continue.”

  4. Step 4Add your personal information

    Fill in your details. When you start typing your country or state, choose the correct entry from the dropdown list. Select “Continue” when you are done.

  5. Step 5Add promotion and purchase details

    Enter your rebate or promotion code in the first field, if you have one. Otherwise, leave that field empty. Select your purchase date. You can also provide the store name, address, and ZIP code.

  6. Step 6Upload your proof of purchase

    Select “Upload Your Receipt.” An original receipt or original invoice is preferred. It must include the purchase date, product, and price.

    If you cannot find the original receipt, you can use a credit card or bank statement instead. Leave only the date, merchant/product, and amount visible. Hide or remove personal information before uploading it.

  7. Step 7Accept the terms

    Agree to the Terms & Conditions, then select “Continue.”

  8. Step 8Review and submit

    Check the information you entered, then select “Submit” to finish registering your Dolphin.

Check your warranty length

Warranty length depends on your model and region. Check your model's product page for its warranty length. Poolbots' pool experts can help by live chat or phone if you need clarification.
