5 Best Dolphin Pool Cleaners – Reviews 2020

1. Dolphin Premier Robotic Pool Cleaner – Top Pick


Dolphin Premier robotic pool cleaner

The Dolphin Premier Robotic is the top pool cleaner made by that company. It’s extremely versatile, which isn’t something we say about pool cleaners often. This cleaner can use multiple different kinds of filter cartridges or a bag. Because you can change those out, you can optimize the machine for different kinds of cleaning operations, ranging from algae scrubbing to leaf removal. That’s part of the reason it’s so effective, but it also keeps track of where it has been to help ensure it gets your whole pool clean.

Like many Dolphin machines, this one is very efficient compared to other kinds of robotic cleaners, but also versus ones that make use of a pool’s pump system. It also has a massive, three-year warranty that’s hard to find on other brands of pool cleaners. If we had one reservation, it would be that it’s not inexpensive, though that’s typically expected when a machine is the best of its kind on the market. If you’re looking for a Dolphin pool cleaner that won’t let you down, this one will keep you happy.

  • High price

2. Dolphin Nautilus CC Plus Automatic Pool Cleaner – Best for the Money

Dolphin Nautilus CC Plus Pool Vacuum

The Dolphin Nautilus CC Plus is another great choice for those who want a Dolphin-brand pool cleaner. This model is robotic, so it’ll keep track of where it has been and make sure to clean your entire pool. Its smart scanning technology helps it target areas that need extra cleaning and help ensure that your pool is as clean as possible. It uses top-load filter cartridges. It’s easy to program, and you can have it run daily every other day or every third day with just a few button presses. Electric pool cleaners tend to be energy-efficient, but this one has a reputation for being excellent in that area.

However, what many people will like the most about this Dolphin machine is its price. You can get it for 30 percent less than the top Dolphin model, so this one is easily the best value for the money. The one area where it struggles is with steps, though if you’re willing to experiment with the floats on the hose, you should be able to add those to its range, too. Overall, this is a good pool cleaner, but its price makes it great.

  • Easy programming
  • Top-load filter cartridges
  • Energy-efficient
  • Great price
  • Not great with steps

3. Dolphin Oasis Z5i Pool Cleaner

Dolphin Oasis Z5

The Dolphin Oasis Z5i is one of the first pool-cleaning robots with any kind of smartphone connectivity. It works largely like the first two on our list, with the exception of its Bluetooth-ready base. You can use Dolphin’s app on your phone to guide the robot through your pool to areas that need a spot cleaning, so you can get your pool in tip-top shape without running a full cleaning cycle. This cleaner uses cartridges, so emptying it is fast and easy. It has a three-year warranty, so you won’t have to worry about anything going wrong.

It also comes with Cleverclean scanning, which allows it to scan the pool and find areas that need extra attention. The one real problem that causes it to fall a few spots on our list is its price. It’s nearly 50 percent more expensive than our top choice. For that extra premium, you’re only getting one feature that you don’t get on other models, and that’s the option of controlling it with a smartphone. While this is a good pool cleaner, most people won’t get good value from that premium price.

4. Dolphin Escape Pool Vacuum – Best for Above-Ground Pools

Dolphin Escape Pool Vacuum

Just because you have an above-ground pool doesn’t mean that you can’t make use of one of Dolphin’s great robotic pool cleaners. The Dolphin Escape Pool Vacuum is designed for use in above-ground pools, which lets you get the superior cleaning you need without having to do it yourself. This cleaner comes with a great oversized debris cartridge, so you can sometimes do multiple cleanings without having to empty it out. When it is time to empty it, it’s super easy to remove and empty the filter cartridge. Plus, this model weighs just 14 pounds, which makes it easier to get it in and out of above-ground pools.

However, many above-ground pools need fine particle filtration. If you’re looking for that, you’ll have to spend extra and get the fine particle filtration basket. It would make sense to bundle it together with this machine, but Dolphin doesn’t, which leads to extra expense. The cord on this one also lacks a dongle, so it can get tangled up on itself. It is one of your best options if you have an above-ground pool, though it won’t be the best choice for all pools.

  • Designed for above-ground pools
  • Oversized debris cartridge
  • Lightweight
  • Fine particle filter sold separately
  • Cord sometimes tangles

5. Dolphin Nautilus Pool Vac

Dolphin nautilus

The Dolphin Nautilus does some things right, but it also has some flaws that make it less desirable than others on our list. One of its big plusses is that it has  the single button operation that makes other Dolphin models so easy to use. It also comes with an anti-tangle swivel, which should be standard, but isn’t found on all robotic cleaners. Plus, it’s relatively inexpensive. While it does cost a few hundred dollars, top-of-the-line models can set you back far more than that.

One thing we don’t like is that it lacks a handle. That makes it harder to lower it into the pool, and also makes it harder to get it back out when the cleaning cycle is over. This model also suffers from a relatively small storage capacity, which means you won’t be able to clean the pool as frequently without having to change the filter cartridges. Ultimately, this machine isn’t a terrible deal for the money. If you’re looking for a discount model that gives you some of the features you expect from higher-end Dolphin pool cleaners, this one will be a good choice.

  • Single button control
  • Anti-tangle swivel
  • Good price
  • No handle for removal
  • Relatively small storage capacity

Buyer’s Guide

What is a robotic pool cleaner?

If you’ve owned a pool before, you may be familiar with the three common types of automatic pool cleaners: suction-side, pressure-side, and robotic. Suction-side cleaners attach to the intake part of your pool and use the power from your pool’s pump to collect debris. Pressure-side models work similarly but instead attach to the other side of the system, the one that’s pushing water into your pool.

These two cleaner types generally aren’t smart. They move around at random, and if you let them go long enough, they’ll eventually cover your entire pool. Another big downside is that they’re dependent on your pool’s pump to work. If your pump is on the weaker side, you may get very mediocre results from pressure- or suction-side pool cleaners.

Robotic models differ in that they don’t attach to your pool’s pump system. Instead, they’re powered by electricity and carry a filter and either a basket or bag with them. That means they’re a great choice for pools with weaker pumps.

While you may think robotic cleaners would have a higher cost of operation, the opposite is often true. Since the pump has to do its own job, plus power the suction-side or pressure-side pool cleaner, it can draw many times the energy it would otherwise use. Consequently, in many cases, a robotic pool cleaner will draw less electricity, leading to a lower cost of operation. It will also put less strain on your pool pump, which could extend its life.

What can robotic pool cleaners do?

One of the hallmark features of a robotic pool cleaner is that it can use electronic equipment. That means it can either keep track of where it has been in your pool, use information from a suite of sensors to figure out where it should go next, or both.

If that sounds futuristic, that’s because it still is to some extent. Most Dolphin cleaners have some version of this technology. However, it seems to work best on the high-end machines, which makes sense. The downside is that you typically have to shell out thousands of dollars to get one of those high-end models. Less expensive models may still have this feature, but they tend to be more hit-or-miss in terms of how well they work.

Robotic cleaners also have an advantage over other kinds of pool cleaners in that it’s harder for them to get tangled. Since they use narrow cords, there’s a lower chance of them getting caught on themselves relative to the pipes other kinds of cleaners use. Plus, they often have swiveling dongles, which further reduce the chance of a tangle.

Since they don’t rely on water pressure to move around, they’re generally more reliable when it comes to climbing steps in your pool or doing waterline cleaning, where they clean above the water for a nice finish. Keep in mind that waterline cleaning isn’t a feature all Dolphin machines have, so if it’s something you want, double-check that your model has it before you buy.


Another nice thing about Dolphin pool cleaners is that they sometimes come with a choice of filter. There are two major categories of filter, each with its own subtype.

The most commonly used type on robotic models is the cartridge. The cartridge is a hard-sided filter that lives inside the cleaner. When it needs to be emptied, you just pop the lid on the robot and dump the filter out. Generally, it needs to be washed off as well, but as soon as that’s done, you’re ready to go again.

Filter cartridges are designed to last for years. Usually, they do last years. However, they tend to be very expensive to replace, so it’s a good idea to treat yours with care.

Other Dolphin cleaners use bags or soft-sided filters. These sometimes fit in the same place cartridges do, and other times they ride externally. While cartridges often have excellent capacity, bags can sometimes hold more, and they tend to be much less expensive to replace.

If your pool is in really bad shape, and has a lot of sharp or hard objects, such as small branches, at the bottom, you may benefit from replacing a cartridge with a bag, as damaging the bag is a much more affordable problem to solve.

Both cartridges and bags come with regular and fine particulate options. If you have serious dirt or algae problems on the walls or a lot of fine dirt in the water, use a cartridge or bag that’s fine-particulate ready. Otherwise, the holes in the filter will be large enough for the dirt or algae to slip through, which ultimately leaves it in the pool.

Which Dolphin pool cleaner is right for you?

Many people look at the prices on Dolphin cleaners and opt out on that alone. It’s understandable, given the price, but it’s important to understand the value that these cleaners can bring. They tend to work very well and have great durability and excellent warranties. They can save you a lot of time when it comes to cleaning your pool, which allows you to spend more time with your family.

While you might be tempted to just buy the lowest-priced Dolphin you can find, that’s not necessarily the best idea, either. If it doesn’t have the features you need, you’ll be upset with it, but still out a few hundred bucks.

It’s a better idea to start by evaluating your pool, and then selecting the model with the features and the filter cartridges or bags that will best clean your pool. Then, you’ll be able to relax and let the robot do its job for years to come.

Individual reviews:


The Dolphin Premier Robotic is our favorite due to its use of cartridges or bags, effective cleaning, and a three-year warranty. The Dolphin Nautilus CC Plus comes in second with its easy programming, top-load filter cartridges, and great energy efficiency. Its great price means that it’s the best overall value for the money. The Dolphin Oasis Z5i has Cleverclean scanning, smartphone compatibility, and a cartridge-based filter system. Its high price keeps it in third on our list. The Dolphin Escape has features that make it good for above-ground pools, but it lacks a fine particle filter and has a cord that sometimes tangles, which makes it poor for other situations. Coming in at last place is the Dolphin Nautilus. It’s a decent discount buy but lacks a handle and has a small filter space, which makes it less convenient than most other units.

While it may seem hard to figure out which Dolphin cleaner is right for you, we hope our reviews and buyer’s guide have made the decision much easier.

Also, some people also really like Polaris pool cleaners. Therefore we’ve written a buying guide for them found here.
