Frequently Asked Questions

Do you have the Dolphin M400 Pool Robot in stock?
Unfortunately we are currently out of stock of this item. Please refer to our review to help you find an alternate.

Where is the Dolphin pool robot shipped from?
The Dolphin M400 Pool Robot will ship directly to you from the closest Maytronics warehouse in the US. Unlike other Dolphin resellers that need to pay for shipping costs to stock the robots into their warehouse and pay for warehouse space, we provide you with the additional cost savings because we ship directly to you from the manufacturer. A win-win for the consumer.

How soon do you ship the robot?
Most orders are shipped within 24 hours. We totally understand that once you've made the decision to purchase a Dolphin that you would like to receive it as soon as possible.

What are the voltage requirements for the Dolphin power supply?
The Dolphin requires a standard 120v outlet for power and should always use an outlet that is protected with a Ground Fault Interrupter (GFI) device. Do not use an extension cord or surge protector to power the Dolphin. Also, the power supply is not waterproof - it is water resistant - so it should be placed in a location where it won't get rained on.

Is this Dolphin M400 Pool Robot capable of scrubbing the waterline?
Yes it does. Besides cleaning the floors and walls, this model is also capable of scrubbing the waterline and removing debris.

Can I keep the pool robot in the swimming pool when not in use?
We (and also the manufacturer) recommend that you remove the Dolphin out of the pool and stored away from the pool when not in use. This will allow you to rinse off the filters of debris and excess chemicals.

What's the purpose of the weekly timer then?
The purpose of the weekly timer is to allow you to keep the robot in the pool for a week and clean the pool during that time. You will need to make sure the filters stay cleaned.

Do I have to purchase any of the accessories to use the Dolphin pool robot?
Absolutely not. The purchase of the Dolphin M400 Pool Robot includes everything you need - no additional products are needed to get your swimming pool sparkling clean.

Do you have product review on the Dolphin M400 Pool Robot?
Every year we update our product reviews - we recently updated our Dolphin M400 Pool Robot product review based on our own knowledge and feedback from our customers.

What is a certified refurbished unit?
A certified refurbished unit is a unit that has been returned to the manufacturer for a variety of reasons. While the unit may have some scratches from handling, the unit has been inspected by factory-certified technicians and meet the same standards as new units. In fact, they are described by the manufacturer Maytronics as being in "like-new" condition.

What comes with the purchase?
The unit comes complete with the robotic cleaner, the power supply and brand new filters - exactly what you would receive with a brand new Dolphin robot. You don't need to purchase anything else to use the unit when you receive it.

Do they come with a warranty?
Every certified refurbished robot come with a full (parts and labor) one year warranty direct from the manufacturer.

Is Pool Partz an authorized reseller for Maytronics?
Yes we are. For over a decade, we have been an authorized reseller of Dolphin robotic pool cleaners for Maytronics. In fact, we are the only online reseller that sells the full line of Dolphin robots exclusively so we are extremely knowledgeable in every model and can make recommendations for the model that best suits your needs and budget.
