Maytronics is known for producing some of the best robotic pool cleaners available, constantly updating technology to make their cleaners more efficient, powerful, and precise. This can be seen in the Dolphin Sigma and the Dolphin Nautilus CC Plus.
The Dolphin Sigma, which is compatible with smartphones, features remote navigation through its gyroscopic guidance and an upgraded processor. Additionally, its tangle-free power cable and multiple DC motors make it a durable option, while its two snap-apart filters and four brushes make it a great choice for keeping your pool clean all summer. The filters and four brushes will keep your pool inviting all summer long.
The Nautilus CC Plus is a quick cleaning option that lacks advanced features but has a fast cleaning cycle and top-loading filters. It can clean pools up to 50 feet with its lengthy cable and CleverClean technology that navigates around obstacles.
Routing and Maneuvering
Dolphin Sigma
The latest version of Maytronics’ navigational software, SmartNav 3.0, paired with a gyroscope, ensures the Sigma robot avoids unnecessary movements and turns. With the MyDolphin app, available for both iPhone and Android, you can control the robot’s navigation in any shaped pool.
The Dolphin Sigma’s 60-foot cable rotates fully, eliminating knots and damaged wires. Its length allows the robotic cleaner to reach every inch of a 50-foot pool, including the walls and waterline.
Dolphin Nautilus CC Plus
The Nautilus CC Plus boasts clever technology in the form of its CleverClean feature. This feature scans your pool to map out the most efficient cleaning path, while also allowing the robot to avoid obstacles such as ladders and drains.
The Dolphin Nautilus CC Plus by Maytronics features a swiveling cable to prevent tangling while maneuvering.
The robotic cleaner is equipped to clean a pool up to 50 feet in size thanks to its 60-foot cable. It doesn’t only clean the floor but also vertical and curved walls.
Conclusion
The advanced navigation system found on every robotic pool cleaner is augmented by the presence of a gyroscope on the Dolphin Sigma model, enabling it to execute precise turns. Both models feature a swiveling cable and the Sigma has the added capability of suctioning at the waterline.
Cleaning Cycles and Scrubbing Action
Dolphin Sigma
The Dolphin Sigma pool cleaner is powered by three 24-volt commercial-grade motors, one of which controls the spinning of the counter-rotating tracks, and the other two operate the double brushes that remove algae and debris.
The power supply of the Sigma features soft-touch buttons that allow you to set a cleaning schedule; choose between daily, twice a week, or three times a week. If you prefer, you can also use the remote control to initiate a cleaning cycle while relaxing in a lounge chair. The cleaning cycle takes only 2.5 hours to complete.
Dolphin Nautilus CC Plus
The Nautilus CC Plus robotic cleaner can handle cleaning any shape of the pool, be it rectangular or oval, thanks to its heavy-duty tracks with a powerful grip and its two deep-scrub brushes that ensure no dirt is left behind.
The CC Plus is equipped with a power supply box that allows you to set a timer for automatic cleaning, even when you’re not at home. The timer can be set to clean once, twice, or thrice a week, depending on the cleanliness level of your pool. Each cleaning cycle takes only 2 hours to complete, making it easy to get your pool ready for a party.
Conclusion
The Dolphin Sigma is equipped with three motors that work together to ensure optimal performance while scrubbing and driving. It also has four brushes instead of two, making the scrubbing action more efficient. Both the Sigma and other robotic cleaners have a timer-equipped power supply and can clean a pool in less than 3 hours.
Filtration and Maintenance
Dolphin Sigma
To increase its capacity for capturing contaminants, Maytronics included two substantial filters in the Dolphin Sigma. These filters, which can be easily detached, are designed to be loaded from the top for easy cleaning. Additionally, the Sigma features a filter indicator to alert you when it’s time to clean them.
Weighing 24.6 pounds when dry, the Sigma falls in the middle of the weight range for robotic pool cleaners. Despite this, it has a well-designed lifting handle with a concave palm grip that makes it easy to remove the robot from the water.
Dolphin Nautilus CC Plus
The Nautilus CC Plus is designed with filters located at the top for convenient access. These filters work together to capture even the smallest particles. Simply rinse them to keep them functioning properly.
Maytronics constructed a lightweight robotic pool cleaner, weighing 19 pounds out of water.
To prevent water from slowing the robot down when removing it from the pool, the quick-release feature expels water quickly. Additionally, the robotic pool cleaner is designed with a textured handle for a secure grip.
Conclusion
Maintaining the filters on robots is simple, particularly with Sigma’s filter alert feature. Both models come equipped with a pair of filters located in a top compartment. Despite being slightly heavier, the Sigma’s handle recess provides a firmer hold.
Sigma vs Nautilus: Two Dynamic Robotic Pool Cleaners
The Sigma and Nautilus CC Plus is constructed for durability with tracks instead of wheels and a pivoting, low-friction power cable. Both models are also designed for easy maintenance, featuring a top-opening door with a dual filter system.
Additionally, you can schedule a cleaning schedule on both robots by setting a timer.
Despite their differences in software – the Sigma has SmartNav 3.0 with a gyroscope, while the Nautilus CC Plus uses CleverClean – both models are highly capable of creating non-repeating cleaning paths. The Sigma also features Bluetooth connectivity for added convenience and is specifically designed to clean the waterline in addition to walls and floor.
The Nautilus CC Plus is incredibly lightweight, thanks in part to its quick water release feature. Despite having only two brushes instead of four like the Sigma, they are wide and do an excellent job of eliminating difficult dirt.
While the Dolphin Sigma boasts additional functionality, both robotic pool cleaners are valuable purchases.
