The Maytronics Dolphin S400 with WiFi is a smart robotic pool cleaner designed for in‑ground pools up to 50 feet in length. It combines app‑controlled operation, active scrubbing, and efficient filtration to deliver hands‑free pool cleaning with minimal effort.

Using the MyDolphin™ Plus mobile app, pool owners can manage cleaning schedules, start or stop cycles remotely, and customize how and when the cleaner operates.

Complete Pool Coverage

The Dolphin S400 is designed to clean the full pool interior, including:

• Pool floors
• Pool walls
• The waterline

Active scrubbing brushes help remove dirt, algae, and debris from surfaces while the cleaner navigates the pool using intelligent scanning technology to ensure consistent coverage.

Smart Control and Scheduling

With built‑in WiFi connectivity, the S400 allows for:

• Remote start and stop
• Weekly scheduling
• Multiple cleaning cycle options

This makes it a strong option for pool owners who want convenient, app‑based control over routine pool maintenance.

Practical Filtration and Easy Maintenance

The S400 features a top‑access filtration system designed to capture both large debris and finer particles. The filter can be easily removed from the top of the cleaner for quick rinsing, keeping routine maintenance simple and mess‑free.

At the end of a cleaning cycle, the cleaner can move toward the waterline for easier removal from the pool.

Designed for Smart, Connected Pool Ownership

The Dolphin S400 with WiFi is well suited for:

• In‑ground residential pools
• Owners who value app control and automation
• Those looking for full floor, wall, and waterline cleaning without manual effort

With smart features, reliable build quality, and manufacturer‑backed warranty support, the S400 offers a balanced option for pool owners who prefer a connected approach to pool cleaning.
