Frequently Asked Questions

Can the Dolphin M400 be used in a salt water pool?
Yes. The Dolphin M400 robotic pool cleaner is designed for use in both traditional chlorine and salt water pools, making it a versatile choice for many pool owners.

Does the Dolphin M400 have WiFi capabilities?
Yes. The Dolphin M400 robotic pool cleaner features WiFi connectivity through the MyDolphin Plus app, allowing you to control your robotic pool cleaner from your smartphone. You can schedule cleanings and manage settings based on the model.

Do I need WiFi to use the Dolphin M400?
This is a very common question. WiFi is not required to operate the robot. Dolphin robotic pool cleaners are designed for simple, plug-and-play operation — place the cleaner in the pool, press the power button, and the cleaning cycle begins automatically. WiFi and app features are optional conveniences, not requirements. Also, if WiFi is unavailable near your pool, the app can also connect via Bluetooth.

What are the voltage requirements for the Dolphin power supply?
The Dolphin requires a standard 120-volt outlet and should always be connected to a GFI-protected receptacle. Extension cords and surge protectors are not recommended. The power supply is water-resistant, but not waterproof, and should be placed in a dry, sheltered location.

Do I have to purchase any of the accessories to use the Dolphin M400 pool robot?
No additional accessories are required. The Dolphin M400 robotic pool cleaner comes complete with everything you need to start cleaning your pool immediately.
