Frequently Asked Questions

Do you have the Dolphin S400 in stock?
Unfortunately we are currently out of stock of this item. Contact us to help you find an alternate or you can refer to our top selling Dolphin models by clicking here.

Where is the Dolphin pool robot shipped from?
The Dolphin S400 will ship directly to you from the Maytronics warehouse in Georgia. 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 S400 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 S400 includes everything you need - no additional products are needed to get your swimming pool sparkling clean.

Why buy from Pool Partz?
For years, Pool Partz has been an exclusive reseller of Dolphin robotic pool cleaners and have thousands of customers that joined the Dolphin family. We fully understand the entire Dolphin product line and just aren't in the business to sell you any brand of pool cleaner like the rest of our competition. Because Dolphins are the best in the industry, we don't sell any other brand. Please think about that before your purchase - do you want to purchase from a reseller that is selling the myriad of brands out there or should you buy from a reseller that is solely committed to the Dolphin line?

Do they come with a warranty?
Every certified refurbished robot come with a full (parts and labor) bumper to bumper 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 so we are extremely knowledgeable in every model and can make recommendations for the model that best suits your needs and budget.
