Dolphin S400 Robotic Pool Cleaner
Reviewed by Robert Knight
Key Features
- Exclusive In-Store Model - As an in-store exclusive, the Dolphin S400 is often more expensive and has fewer features than some online models like the Dolphin Quantum, Dolphin Premier, and Dolphin Sigma.
- myDolphin Plus App - An upgrade over the Dolphin S200, the Dolphin S400 features the myDolphin Plus app for enhanced control.
- Lower Suction Power - The Dolphin S400 has smaller motors and less suction power by over 500 gallons per hour compared to the new ProLine's Commercial-Grade Motors, despite being more expensive.
- Full Pool Coverage - The S400 cleaned our entire test pool from the floor to the waterline as it vacuumed debris into its top-loading filter.
- 3 Year Warranty - The Dolphin S300 has the longer 3 year warranty, which is great to see as usually only ProLine models include. But, we should expect it to have it as it is more expensive than ProLine models.
- Includes Caddy - The S400 includes the Dolphin Universal Caddy, which we loved to see at this price point.
