Dolphin Nautilus CC: Entry-Level Option for Smaller Pools
The Dolphin Nautilus CC is the most affordable model in this Dolphin robotic pool cleaner comparison, designed for pools up to 33 feet in length. According to the Maytronics official specs, this cleaner works in both in-ground and above-ground pools, making it one of the most versatile entry-level options available.
At just 14.8 pounds, the Nautilus CC is the lightest model in this Dolphin robotic pool cleaner comparison. It features a top-loading filter basket that you can clean without flipping the robot over, and its 4,000 GPH suction rate handles leaves, dirt, and sand effectively. The trade-off for the lower price is no weekly timer, no anti-tangle swivel, and no waterline scrubbing. For pool owners on a tight budget, this model still delivers reliable performance.
Dolphin Nautilus CC Plus: The Best-Selling Model for Pools up to 50 Feet
The Dolphin Nautilus CC Plus is the best-selling model in this Dolphin robotic pool cleaner comparison for good reason. According to CNET’s testing of 20 robot pool vacuums, this cleaner took the top spot for corded models, with the reviewer noting it “hits all the marks for cleaning and scheduling via its app.”
The Maytronics product page shows this model bumps the maximum pool length to 50 feet, adds a higher 4,500 GPH suction rate, and includes a weekly timer and an anti-tangle swivel cable. The Wi-Fi version connects to the MyDolphin™ Plus app for remote scheduling and control. At around $849, this model hits the sweet spot between price and capability, making it a standout in any Dolphin robotic pool cleaner comparison.

Dolphin Premier: Premium Model with Full Waterline Coverage
The Dolphin Premier steps up to full floor-wall-waterline cleaning and adds Multi-Media filtration — a system that lets you swap between a fine cartridge, an ultra-fine filter, and an oversized leaf bag. According to Poolbots, the Premier was rated a top performer for its comprehensive cleaning capabilities.
The Maytronics official page confirms this cleaner covers floors, walls, and waterline of a 50-foot pool in around three hours, and it’s backed by a 3-year warranty — 50% longer than the Nautilus CC Plus. As Premier Robotics notes, the Premier is “a true robotic pool cleaner — no booster pump, no plumbing, 90% more energy efficient.” For pool owners who need waterline scrubbing, this Dolphin robotic pool cleaner comparison shows the Premier is the clear choice.
Dolphin Sigma: The Flagship Model with Gyroscope Navigation
The Dolphin Sigma is the top-of-the-line model in this Dolphin robotic pool cleaner comparison. According to The Robot Shop, it’s the “flagship Dolphin pool robot with gyroscope mapping, triple motors, and smartphone control.” The Robotic Reviews gave this model an overall score of 98, calling it “the most advanced pool robot we’ve tested yet.”
The Sigma adds Wi-Fi and the MyDolphin™ Plus app, letting you start, stop, and schedule cleanings from your phone. A built-in gyroscope and SmartNav 3.0 navigation help this model map your pool and follow the most efficient cleaning path. Like the Premier, it cleans floors, walls, and the waterline, and it comes with a 3-year warranty. The Sigma weighs 24.6 pounds — heavier than the others — and runs a 2.5-hour cycle. Any Dolphin robotic pool cleaner comparison would place the Sigma at the top for advanced features.
