Owning a pool means hours of fun for the entire family. It, unfortunately, can also mean hours of cleaning. If you don’t keep your pool consistently clean, it not only becomes an unusable eyesore – it also becomes a breeding ground for potentially hazardous bacteria. Luckily, there are a variety of automatic, robotic cleaning devices that take the hard work out of cleaning a pool.

Introduction
Dolphin is a leading name when it comes to automatic pool cleaning companies. The Dolphin Nautilus CC Plus and the Dolphin Premier Robotic In-Ground Pool Cleaner are both amazing devices that promise to leave your pool pristine.
Yet because they vary significantly in price, it’s important to take a look to see which is truly the superior product.

Cleaning Capabilities
Dolphin Nautilus CC Plus
Sold at the lower price point, the Dolphin Nautilus CC Plus still boasts incredible cleaning capabilities. It features a powerful dual brush system that loosens even stubborn dirt and debris before using its powerful suction.
It can clean, vacuum, and filter an entire pool in under 3 hours, while the convenient filter system also makes cleaning a breeze when cleaning is complete.

Dolphin Premier
The Dolphin Premier, however, has a revolutionary MultiMedia feature that offers four different media types in one device. If you are looking to clean even fine algae and other debris that other pool cleaners miss, this device’s micro-filter is the one for you. Similarly, if you have large leaves that need to be picked up, the oversized debris bag is the perfect fit.
While the Dolphin Nautilus CC Plus has impressive cleaning and filtering systems, the Dolphin Premier’s MultiMedia features a unique way to customize your cleaning needs. This allows you to choose the best fit possible without having to compromise.
Overall, the Dolphin Premier fits a variety of cleaning needs in one device.

Motor Efficiency
Dolphin Nautilus CC Plus
Unlike other devices, the Dolphin Nautilus CC Plus works independently from your pool’s pump and filter. This feature means that the motor functions by using only a fraction of the energy compared to similar devices currently on the market.
Dolphin Premier
The Dolphin Premier, however, has a 24-volt motor that operates using approximately 90% less power than your average AC booster pumps. The result is a 180-watt motor that costs close to 5-cents per hour to operate.
While both of these robotic pool cleaners were designed with efficiency in mind, the Dolphin Premier appears to have a much more efficient motor than the Dolphin Nautilus CC Plus. While powerful, using the Dolphin Premier won’t increase your energy bill an exorbitant amount.

Smart Features
Dolphin Nautilus CC Plus
The Dolphin Nautilus CC Plus is an impressive device that functions on a higher level than average pool cleaners. Not only does it feature a weekly timer for a customizable clean, it also uses the smart navigation to scan your pool floor. Unlike other products that clean in a random pattern, this pool cleaning device makes sure that it thoroughly covers every inch of your pool.
Dolphin Premier
The Dolphin Premier pool cleaner takes smart cleaning to the next level. It features Smart-Nav software that maps your pool and calculates the most efficient, optimal way to clean every area of your pool. Along with intelligent microprocessor control, you can set this device to run daily or 2 – 3 times per week, ensuring your pool is also consistently and completely cleaned.
While neither of these devices cleans in an inefficient random pattern like other pool cleaners, the Dolphin Premier uses cutting-edge technology to ensure that your pool is always spotless. The inclusion of Smart-Nav software sets this device apart from the Dolphin Nautilus CC Plus.

Ease of Use
Dolphin Nautilus CC Plus
This model has a user-friendly design. Using patented Dolphin Swivel Technology, it comes complete with a swivel cable that prevents unsightly tangling. Instead of dealing with twisted and tangled cords, you’ll be able to enjoy your pool as soon as possible.
Dolphin Premier
The Dolphin Premier is very similar when it comes to its convenient design. It features an intelligently engineered underwater robotic cable swivel. This 360-degree cable ensures that you don’t have to worry about cables becoming tangled when in use, which totally destroys the efficiency of the machine.
Both the Dolphin Nautilus CC Plus and the Dolphin Premier both are designed with a cleverly designed Dolphin Swivel that decreases tangling. You will never have to worry about a tangled cord giving you a headache with either of these Dolphin pool cleaning devices.
User Reviews
Dolphin Nautilus CC Plus
Users of the Dolphin Nautilus CC Plus had generally positive things to report. Users loved both its efficiency and its cleaning power. Multiple users claimed, however, that this device easily got stuck in unusually shaped areas such as cement stairs and ledges.
Other users also reported that their devices malfunctioned easily and had to be sent to the manufacturer. With that said, most had positive things to say about this product.
Dolphin Premier
Pool owners who used the Dolphin Premier had generally good things to say about this pool cleaner. Many commented on its amazing performance, while others claimed that it was a must-have for any in-ground pool owners.
The negatives of this product appeared to be that this pool cleaner was somewhat finicky and difficult to clean. Those who had mastered this product, however, seemed to enjoy its overall functionality.
