When choosing a premium robotic pool cleaner for in-ground pools, the Dolphin Nautilus CC Plus vs Dolphin M600 stand out as two of the most competitive options available. Manufactured by Maytronics, both models promise high-performance cleaning, reliability, and intelligent automation.
However, while they share the same brand lineage, they cater to very different needs—one focusing on affordability with smart scheduling, and the other pushing the limits of technology and power for elite pool maintenance. This detailed comparison explores their features, cleaning performance, smart capabilities, and real-world usability to help pool owners make an informed decision.

Differences Between Dolphin Nautilus CC Plus vs Dolphin M600
Design Comparison
The Dolphin Nautilus CC Plus Wi-Fi is built for in-ground pools up to 50 feet and features a 60-foot anti-tangle swivel cable, allowing it to maneuver freely across the pool floor, walls, and waterline. With a weight of only 19 pounds, it’s easy to carry, lift, and clean, making it a user-friendly choice for homeowners prioritizing portability.
In contrast, the Dolphin M600 is a more advanced and robust machine. It uses a floating swivel-free cable system designed to avoid tangling altogether, thanks to internal gyroscopic controls and multidirectional drive. Weighing 24.6 pounds, it’s heavier than the Nautilus CC Plus Wi-Fi, but its solid frame, integrated carry handle, and precise motor control give it unmatched balance and traction.
The M600 also includes lateral brushes for enhanced corner and edge cleaning—something the Nautilus CC Plus Wi-Fi lacks. Its wide cleaning path and 4-wheel drive system allow it to traverse even difficult pool terrains such as inclines or raised edges.
Winner: Dolphin M600
The M600’s superior build quality, better traction system, and lateral brushing give it the design advantage for large or uniquely shaped pools.
Cleaning Performance Comparison
The Nautilus CC Plus Wi-Fi features dual active brushes that spin rapidly to dislodge algae, dirt, and grime from pool surfaces. With a 4500 GPH suction rate, it efficiently captures debris and circulates pool water during cleaning. Its top-loading filter basket includes both fine and ultra-fine cartridges, allowing it to handle small and large debris without clogging.
The Dolphin M600, however, takes cleaning performance to a new level. It uses dual front and rear active brushes, plus lateral spinning brushes on its sides, ensuring comprehensive scrubbing coverage—especially in corners and tight crevices. Its 5000 GPH suction rate exceeds that of the Nautilus, making it more effective in pools with fine sand, silt, or heavy leaf loads.
The M600 also features a multi-layer filtration system that separates coarse, fine, and ultra-fine debris for optimal performance and extended runtime between filter cleanings. It adapts its cycle time dynamically, often completing a full clean in as little as 1.5 hours, thanks to smart scanning and efficiency-focused algorithms.
Winner: Dolphin M600
With more brushes, stronger suction, and superior filtration, the M600 delivers commercial-grade performance in residential pools.
Feature Comparison
Both models are equipped with Wi-Fi connectivity and are controlled through the MyDolphin Plus mobile app. Users can start, stop, and schedule cleanings remotely, receive alerts, and monitor cleaner status in real time. However, the M600’s app integration is more advanced, offering multi-mode cleaning (e.g., quick clean, floor-only, full coverage), cleaning reports, and adaptive navigation adjustments.
The Nautilus CC Plus Wi-Fi offers basic scheduling through the app, such as setting daily or weekly cleanings. It’s intuitive and reliable, but lacks customization beyond standard intervals and cannot adjust its behavior based on pool shape or debris levels.
The M600 also includes a pickup mode, where it drives to the side of the pool for easy retrieval—eliminating the need to tug the cord manually.
Winner: Dolphin M600
With deeper integration, adaptive modes, and premium convenience features like pickup mode, the M600 offers a smarter, more autonomous cleaning experience.
