Budget Option

Dolphin Nautilus Plus Robotic Pool Cleaner
The Dolphin Nautilus Plus Robotic Pool Cleaner is an advanced, easy-to-use robotic pool cleaner that is designed to scrub, vacuum and filter in-ground residential pools of up to 50 ft. in length.

Maytronics has launched two versions of this particular robotic pool cleaner – The Dolphin Nautilus CC and the Dolphin Nautilus CC Plus. Both models have almost similar features with just a few differences between the two. The main point of difference lies in the cycle time. The Nautilus Plus has a shorter cycle time of 2.5 hours as compared to 3 hours of the Nautilus.

Its top loading filters are easier to remove and clean than the bottom loading filters of the old Nautilus model.

The Dolphin Nautilus CC Plus has an anti-tangle swivel cable, but a caddy is not included. It does not have a remote control and it is not compatible with the MyDolphin Bluetooth app.

This internet-only model is covered by a 2-year limited warranty. The plastic parts, power supply, cable and motor is covered for 24 months. The brushes, tracks and filters are not under warranty.

The Dolphin Nautilus CC Plus is a pool-cleaning machine. Literally. A robotic pool cleaner, you set it up and set it loose. The Clever Clean system uses onboard sensors to map an optimal path through your pool to maximize its own efficiency. It can clean an average pool in about two hours.

Once in operation, the sensors can also detect obstacles in the bottom of your pool, avoid them and return to the charted path without very little interruption in its schedule.

Some robotic pool cleaners would cost you an arm-and-a-leg to do this, but the Dolphin Nautilus CC Plus does this at the price of a top-end pressure-side pool cleaner, without the few hundred dollars’ extra expense for a booster pump.

Best of the Best

Dolphin Oasis Z5i Robotic Pool Cleaner
The Dolphin Oasis Z5 is one of the latest models produced by the company. Its overall performance is excellent and its advanced features will take your pool cleaning to the next level.

The Z5i’s cleaning ability is on par with what you’d expect from a pool robot of this price.

It scrubs and vacuums the entire pool, removing algae, sand, leaves and all kind of debris. It easily replaces your pool boy or pool cleaning service.

If anything, it cleans better than a human. It’s also much better than traditional suction or pressure side automatic cleaners.

We all want the best in life and so as with the products, we want to own. This robotic pool cleaner is almost perfect and when it comes to ease, this is the one we recommend.

Did you encounter serious trouble to clean your pool in traditional ways? Are you looking for the best and trouble-free pool cleaner? Then the Dolphin Oasis Z5i Robotic pool cleaner is one of the best performing robotic pool cleaners.

Dolphin Premier Robotic Pool Cleaner
The Dolphin Premier is an advanced residential pool cleaner made by Maytronics, the world’s leader in robotic pool cleaning technology. Packed with high-tech features, the Premier has a lot to offer, including Maytronics’ excellent SmartNav mapping system. It’s programmable, too, and can be run daily, 2x per week or 3x per week.

It comes with a few quirks, however. The unit is heavy, so lifting it out of water may be hard on some. And, it’s not the best at cleaning steps.

In terms of raw cleaning potential, there are few pool cleaners — even robotic pool cleaners — that can match the performance of the Dolphin Premier. Its four-media cleaning options make this perfect for sweeping up the grit of a summer windstorm and autumn’s falling leaves with a quick swap-out of a filter.

It also comes with advanced controls that allow it to chart its own cleaning course to work quickly and efficiently. There are good reasons why the Premier is considered Dolphin’s top-shelf pool cleaner.

It’s only predictable, then, that it will cost you a pretty penny. This one is expensive, even allowing for the fact that inground pools are generally top-dollar investments. Its manual operation mode is also less than desirable.

Dolphin sank its best efforts into making this a high-end robotic pool cleaner to the detriment of its manual mode. Then again, you’re not shelling out this kind of money for a pool cleaner that requires that you do a whole lot of work.

Ultimate buying guide for a Dolphin pool cleaner

If you are going to purchase a dolphin pool cleaner then there are certain things that you should check in your product. These things play an essential role in the overall working and satisfaction. In this buying guide we will cover all of these essentials for you, so check them out thoroughly:

Warranty period

Just like every other product in the market, the warranty period is an important factor for a Dolphin pool cleaner too. There are manufacturers who offer you a long warranty period as 5 years.

So, while shortlisting the perfect dolphin pool cleaner for your needs, make sure to check for a period with a longer warranty.

Coverage area

Every dolphin pool cleaner has its own specific coverage area. Some are fit for small pools while there are others that are better for big ones. So, while purchasing, do a measurement check beforehand so that you can choose the perfect fit for your needs.

Otherwise, if you purchase a product that offers abundance or scarcity in the cleaning work, all you will get is dissatisfaction.

Filter loading position

The position of the loading filter plays a very important role in overall satisfaction. There are products that offer top load while some of them come with a side or center-load filters.

So, if you prefer easy access then Dolphin pool cleaners with top load filter are the perfect pick for you.

Water pump or Hose requirement

Most of the heavy-duty products related to pool require a booster pump or hose for operation. But, there are few exceptions to this one. As these equipment rise up the cost too exponentially, there are several dolphin cleaners that do not require any sort of pump or hose.

So, it is better to go for those options which offer you this kind of freedom.

Energy consumption

One of the most important factors that affects the overall price frame is the energy consumption of the model.

The best way to keep this aspect in your favor is to find a pool cleaner that packs a low voltage motor. It will consume a lot less and you will save plenty of power.

High-tech features

There are some great options in the market that offer several high-tech features such as SmartNav scanning algorithms and Vectored Thrust Power Jet.

These features are kind of an add-on but they add to the overall accessibility and usage of these robotic swimming pool cleaning systems.
