Differences Between Dolphin M400 vs Dolphin M600
Design Comparison
Both the Dolphin M400 and Dolphin M600 are engineered for in-ground pools up to 50 feet, equipped with a 60-foot tangle-free swivel cable for optimal maneuverability. While the M400 carries a slightly heavier frame at 25 pounds, the M600 comes in at 24 pounds and integrates an ergonomic handle for easier lifting.
The M600’s design is more modern and user-centric, with intuitive access to the filter basket and a better-balanced chassis. Its Pick Me Up mode allows it to surface near the pool edge when summoned via app, making retrieval significantly easier—something the M400 lacks.

With an ergonomic design and retrieval-friendly features, the M600 offers greater ease of use in daily operation.
Cleaning Performance Comparison
Both models feature dual active brushes that spin at double speed, effectively removing algae and stubborn debris. They provide full pool coverage, including floor, walls, and waterline scrubbing, ensuring deep cleaning across all surfaces.
The M400 delivers a robust 5000 GPH suction, paired with top-load fine and ultra-fine filter cartridges, ideal for collecting dirt, leaves, and microscopic particles. Its 2 or 2.5-hour cleaning cycles offer good flexibility for regular maintenance.
The M600 maintains the same 5000 GPH suction, but improves on cleaning performance with a multi-layer filtration basket that separates large debris from fine particles, preventing clogs and maintaining stronger suction throughout the cycle. It also offers three cycle options (1.5, 2, and 2.5 hours) for increased control based on pool condition.
Winner: Dolphin M600
With enhanced filtration and adjustable cycle times, the M600 offers more consistent and efficient cleaning even in high-debris environments.
Feature Comparison
Both robots are equipped with Wi-Fi and MyDolphin Plus app integration, supporting weekly scheduling, remote start/stop, and cycle customization. However, the M600 raises the bar with SmartNav 3.0, a navigation system that maps the pool more intelligently and ensures more efficient pathing with minimal overlap.
The Dolphin M600 also includes Pick Me Up mode, which directs the robot to the edge of the pool for easy retrieval. This, along with its modernized diagnostics and updates via the app, enhances long-term usability.
While the M400 is no slouch with its reliable performance and smart scheduling, it doesn’t match the automation and intelligence of the M600’s ecosystem.
Winner: Dolphin M600
The M600’s smarter navigation, retrieval assist, and user-focused features deliver a premium connected experience.
