Features of the Product

All-Around Cleaning Capability

The Nautilus Plus don’t just clean the pool floors, it also cleans the steps, stairs, and walls. How awesome is that? This cleaner is best for pools that are 50 feet long, and it can clean for only two and a half hours. It could finish the job faster if you have a smaller in-ground pool. The Nautilus Plus also scrubs walls, unlike other pool cleaners that just vacuums. The suction of this cleaner allows it to efficiently pick up debris while also enhancing water flow and filtration. The Nautilus Plus even expands during the cleaning process, enabling it to perform a thorough cleaning.

Swivel Cable

Say no to tangled cords! All Nautilus pool cleaners have a swivel cable that lessens the tangling up of a long cord, allowing them to perform their job without a hindrance.


This robotic pool cleaner doesn’t depend on the system of your pool, which means it won’t increase the operating costs too. Remember, pool cleaners that use the pool’s pump and filter can raise the price.

Easy-to-Clean Cartridge Filter System

Pool cleaners also need to be clean before they do some cleaning. Because most of us (if not all) hate the part of cleaning the filter because it’s taxing, Dolphin by Maytronics came up with a spring cleanup option for this pool cleaner. The system was made to gather dirt, leaves, debris, and other particles that float around your pool. Thanks to the larger capacity of the filter in Nautilus Plus, you won’t have to clean it over and over again because it gathers a lot of dirt.

IntelliScan Technology

Nautilus Plus also features IntelliScan Technology that allows it to scan your pool, study it, then proceed to areas that need extensive cleaning. This is possible thanks to the GPS-like function in the cleaner which scans the pool in advance. It then puts into memory the measurements, edges, corners, and shape of your pool. And because of the climbing brushes and rings, it can clean your pool no matter what its form is.

Why Should You Buy the Dolphin 99996403 Nautilus Plus?

The Nautilus Plus is worth your money because of the fancy features it offers, and because it is one reliable cleaner. A lot of customers have invested in this cleaner, and it is still popular among first-time pool owners because of its efficiency. It saves time, is durable, energy-efficient, and great at cleaning. Plus, it even comes with two different filter cartridges: a mesh screen (for coarse filtration) and a pleated polyester fiber (for fine). The Nautilus Plus sanitizes pool water efficiently, which allows you and your family to enjoy your pool without debris or algae. Besides, it’s one of the most renowned products in the pool cleaning industry, and it comes from a trusted brand that has been operating since 1983.

A lot of customers said installing the Nautilus Plus is easy-peasy. Most of them loved how the cleaner removes dirt in more or less two hours only. The customers also commented on how effective it works, keeping the pool sparkling clean. They said the power cord is longer than other pool cleaners, which is advantageous and much better. Others also admitted that they were skeptical to purchase the product at first, but then after using it, they realized they made a wise decision. Most customers also loved how it can get to the hard to reach areas of the pool and still manage to cleanse those parts. The cleaner is quiet too, which was another thing pool owners loved about the Nautilus Plus. The item is also moderately priced but performs exceptionally according to many customers. The side handles were also appreciated because of their convenience. Customers also said it’s a sturdy pool cleaner. In a nutshell, a lot of customers loved the product because it has exceeded their expectations.

For all that, there are still complaints about the Nautilus Plus. One would be how it couldn’t get to the creases of the sharp angles in a pool because of its square shape and large size. Some customers also said it gets stuck quickly especially near steps, which is something that calls for babysitting. A few pool owners said it only lasted for two years, and some said large leaves get stuck in the intake slots found at the bottom of the cleaner.


Regardless of what a few people say, the Nautilus Plus still does a fantastic job of cleaning the pool thoroughly. So, before you say no to this product, remind yourself that there’s no perfect pool cleaner. Who knows? The Nautilus Plus might not be the right one for a few pool owners, but it could be the right one for you. All you have to do is give it a chance.
