Differences Dolphin Nautilus CC Plus vs Dolphin M600
Pool Compatibility and Cleaning Range
Both robotic cleaners are rated for in-ground pools up to 50 feet, but their effective usage differs in terms of pool complexity and feature depth. The Dolphin Nautilus CC Plus WiFi is built for standard residential pools, handling rectangular or oval shapes efficiently with its CleverClean smart navigation. It thoroughly scrubs the floor and walls, offering complete coverage for everyday cleaning demands.
The Dolphin M600, however, is engineered for larger, more complex pools, including those with irregular shapes, tanning ledges, steep slopes, and multiple depth levels. It delivers full floor, wall, and waterline cleaning thanks to PowerStream mobility and a multi-axis gyroscope that guides its precise pathing. It’s built for users who expect high-performance maintenance across every surface.
Winner: Dolphin M600
With full waterline scrubbing, adaptive movement, and better terrain compatibility, the M600 dominates in high-end pool coverage.
Cleaning Performance and Scrubbing Power
The Nautilus CC Plus WiFi features dual high-speed active brushes that rotate twice as fast as the robot itself. These scrub away algae, fine debris, and sticky grime from floors and walls. It’s more than sufficient for regular weekly maintenance in moderately used pools.
The M600 brings next-level scrubbing with its dual multi-directional brushes that spin independently. This allows for dynamic contact with complex surfaces, including tile lines, irregular corners, and slippery waterlines. Combined with its PowerStream technology, the M600 maintains consistent wall grip for extended vertical and lateral cleaning.
Winner: Dolphin M600
Its multidirectional scrubbing and enhanced wall-climbing ability outperform the Nautilus on every front, especially in demanding cleaning environments.
Filtration and Debris Handling
The Nautilus CC Plus WiFi includes a top-load dual-cartridge filtration system, combining fine and ultra-fine filters to trap a broad range of debris. From leaves and twigs to sand and pollen, this system keeps residential pool water sparkling clear. Filters are easy to remove and rinse after each cycle.
The M600 enhances this approach with a multi-layer filter basket that separates large debris from fine particles automatically. Its basket holds significantly more debris, making it ideal for heavily wooded areas, large pools, or homes with high dirt exposure. The design also reduces clogging and supports longer cycles without losing suction.
Winner: Dolphin M600
With greater capacity, better debris separation, and less frequent cleaning, the M600 provides premium filtration for serious pool hygiene.
The Nautilus CC Plus WiFi utilizes CleverClean scanning, a reliable algorithm that maps the pool’s floor and wall surfaces for efficient coverage. It avoids random movement, optimizes its path, and minimizes overlap. Its 60-foot swivel cable keeps the robot from tangling during longer cleaning sessions.
The M600 steps up with a dynamic 3D mapping system, advanced gyroscopic sensors, and multi-directional mobility. These combine to form a more adaptive and responsive cleaning routine, especially in free-form or non-standard pools. It learns the layout over time and adjusts accordingly.
Winner: Dolphin M600
Its sophisticated mapping and real-time trajectory correction make it smarter, faster, and more efficient at full-pool cleaning.
Smart Features and App Control
The Nautilus CC Plus WiFi connects to the MyDolphin Plus app, enabling users to start/stop cleaning cycles, set weekly schedules, and monitor progress remotely. It includes three scheduling options and a straightforward interface for homeowners.
The Dolphin M600, via MyDolphin Plus Premium, includes enhanced remote management with cycle selection, waterline-only mode, cleaning history, filter status alerts, and Lift-Out Assist—a feature that automatically drives the robot to the waterline for easy removal. The app also allows advanced scheduling and fine-tuning of cycle intensity and path preference.
Winner: Dolphin M600
Its premium app experience offers broader functionality, true customization, and intelligent user alerts, elevating smart pool maintenance.
Cable Design and Lift-Out Convenience
The Nautilus CC Plus WiFi uses a 60-foot swivel cable, which minimizes tangling and supports uninterrupted movement across large pools. However, users must manually retrieve the robot after each session, sometimes requiring extra effort if the unit is at the far end or below water level.
The M600 also features a 60-foot swivel cable, but adds the exclusive Lift-Out Assist feature. Once a cleaning cycle is complete, the robot positions itself vertically at the waterline, allowing for minimal resistance during removal.
Winner: Dolphin M600
The Lift-Out Assist transforms the post-cleaning experience, making the M600 far more convenient to handle.
Waterline Cleaning and Vertical Coverage
One of the Nautilus CC Plus WiFi’s most notable limitations is that it does not clean the waterline. While it performs exceptionally well on floors and walls, it stops just short of the critical scum line at the top of the pool.
The M600 excels in this regard with dedicated waterline scrubbing, using its smart gyroscopic orientation and PowerStream flow control to maintain stable vertical contact along the pool’s top edge. This function alone drastically improves overall pool aesthetics and cleanliness.
Winner: Dolphin M600
Waterline cleaning is essential for full maintenance, and only the M600 delivers it consistently and effectively.
Weight and Handling
The Nautilus CC Plus WiFi weighs in at 19 lbs, making it relatively light for a robotic cleaner. It features a carry handle and compact body, easy enough for most users to lift and transport without strain.
The M600 is heavier at 24 lbs, reflecting its more powerful motor, larger debris basket, and internal gyroscopes. Despite its weight, Lift-Out Assist and ergonomic design make it surprisingly manageable.
Winner: Dolphin Nautilus CC Plus WiFi
For those prioritizing portability and manual handling, the Nautilus is lighter and easier to manage.
Durability and Warranty
The Nautilus CC Plus WiFi comes with a 2-year warranty, standard for residential-grade Dolphin robots. It is well-built with durable plastics and waterproofing suitable for weekly use during swim season.
The Dolphin M600 extends that to a 3-year warranty, backed by Maytronics’ premium support program. It’s constructed from reinforced materials and designed for frequent use in high-debris, large-pool environments, making it more rugged over time.
Winner: Dolphin M600
With a longer warranty and more robust build quality, it promises greater longevity and reliability.
