Best Robotic Pool Cleaners

Shopping online is supposed to be equally easy, but the truth is that it’s no longer the fast, simple process that it used to be. Misleading product descriptions make it harder than ever to get a good feel for a product, and with an investment as important as a robotic pool cleaner, you don’t want to go into the deal with less than full knowledge.

We’ve also included a buyer’s guide, which will help you understand the buying process, even if you’ve never owned a robotic pool cleaner before.

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

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.

Buying Considerations

Here are some buying considerations that will help you choose your robotic pool cleaner.


Pool cleaners can vary widely in price. In most cases, the more functionality and features a unit has, the higher the price tag. Consider your budget as well as the size of your pool and how much debris you regularly find in it when determining how much to spend on a unit.

How Smart Do You Want Your Robotic Pool Cleaner To Be?

Early robotic vacuums were formulaic and unsophisticated, operating with basic algorithms that ensured the same patterns every time.

Not anymore. High-end robotic pool cleaners can determine the layout of your pool and clean accordingly. This means you don’t need to worry about large swaths of your pool bottom going unattended. A sophisticated cleaning cycle process will cost you more money, but it’s worthwhile for buyers that prioritize performance.

Pool Size

The size of your pool is a factor that you won’t want to ignore. Even really good cleaners have their limitations, and each cleaner is pre-programmed with a specific range. Too small a range and your pool will suffer.

If you have a pool that is of typical size and shape, most options will suit your needs, but it’s always best to make sure before finalizing a purchase.

What Is Your Pool Made Of?

Your pool’s liner material can also determine the type of cleaner you need. Some cleaners specifically state the type of material they are best used with—pebble tech, vinyl, etc.

Others claim to be universal but may still damage softer materials. If your pool includes delicate materials like fiberglass or tile, be mindful of the vacuum you choose.

Why Buy a Robotic Cleaner?

A Robotic cleaner is much better than other types of automatic pool cleaners because you don’t have to attach them to your pool. It is extremely easy to use, as all you have to do is install it properly and then plug it in to see it work efficiently.

Here are some reasons why a robotic cleaner is the best buy for inground pools.

– These cleaners are extremely versatile and efficient, as they can tackle all types of debris, big or small. You can use them on any type of pool surface; in fact, they are quite suitable for tiled pools as well as vinyl pools. A built-in filtration system adds to its effectiveness.
– These cleaners are extremely environmentally friendly, as they don’t release any chemical or toxin while working. Your pool stays in a perfect condition and you never have to worry about any health issues.
– These pool cleaners don’t require serious maintenance; in fact, all you have to do is empty the filter bag, rinse it, and you’re ready to use your cleaner again.
– These robotic cleaners don’t rely on your pool’s filtration system or pumps, which means they are extremely energy efficient. They work fast and finish the task in a timely manner.

Overall, robotic cleaners are extremely useful and efficient, but it is worth mentioning that they can be quite expensive, especially compared to the other types of automatic pool cleaners. The price can go up considerably if you need a cleaner for vinyl pools. To prevent tangled cables, you have to buy models with a swivel cord, which may cost a little more.


Choosing best robotic pool cleaner doesn’t have to be difficult. With proper knowledge and research, rest assured that you’ll end up with a product that works best for your pool and of course, your budget.

They are by far the most efficient and effective pool cleaners. They can handle any kind of debris, vacuuming it directly into its own filter.

Plus they have their own smart technology that helps them master any shape or sized pool. Not only does this robotic cleaner help you with pool cleanliness, it also helps circulate water, guaranteeing a fresher swim.
