Frequently asked questions
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.
Does this unit have WiFi capabilities?
Yes it does. The MyDolphin Plus app allows you to use your mobile device to remotely control your Dolphin. Set cleaning schedules and other features will vary depending on the model.
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 are there so many models to choose from?
There are a couple of reasons why Maytronics have many different models. First and foremost, swimming pools come in different styles (i.e. above ground and in ground swimming pools) and sizes (i.e. small above ground versus a large commercial Olympic swimming pool) and therefore there are different robots that is optimal for every pool type. Additionally, these Dolphin pool cleaners are sold in different markets like brick and mortar stores vs. online. The great news about purchasing from Pool Partz is that we have exclusive access to the full line of Dolphin robotic pool cleaners so we can offer the model that you like best. We can also offer unbiased product reviews since we can simply highlight the differences between the models. We assume you already know that the Dolphin line of robotic pool cleaners are the best in business and that you would like to purchase one.
