Dolphin Premier Robotic Pool Cleaner


The Top 10 Features to Look For

The robotic pool cleaner market is growing rapidly as the market shifts away from inefficient technology improves. This has flooded pool owners with hundreds of options to choose from, often without much precedence as to what works and doesn’t. With so many different looks, specifications, and features across the board, how do you know which robot is right for you? Not to worry – we’ll help you find the best robotic pool cleaner for 2023.

Welcome to a quick crash course in robotic cleaner ownership. We’ll walk you through the top 10 features for any robot, and we’ll help you understand which ones are essential and which ones are nice to have. Buckle up– it’s time to talk robots that like water.

The Difference Between Essential and Nice to Have Features

Some of these features are essential to owning the best robotic pool cleaner. Essential as in, why even have a pool robot if it doesn’t have it? These are the traits that every cleaner should not only have, but execute well, too. Unfortunately some of the cheapest models you’ll find on sites like Amazon are stripped down models. You’ll notice some models drop important capabilities to lower the price by 20-30%. These units always have shorter warranties as well.

We’ve labeled some of our top 10 features as “Leading Edge Tech”. This means they’re very nice to have, but they don’t make or break a pool robot.


1 Tile and Waterline Scrubbing

All pool cleaners can clean the bottom of the pool. But only the best can clean the upper part of the wall where the water stops. You may have heard this problematic area referred to as the scum line. This area is known to harbor bacteria, algae, and biofilm. Around 90% of pool robots advertised as wall cleaning only clean the lower wall. They’re simply not capable of reaching the upper wall and tile line.

You may have noticed rotating dual stabilizers on a few robots. It’s not for looks. It’s the secret to maintaining position on the upper pool wall. These premium pool robots attach to the wall and scrub, even with up to 40% of the robot above the water. The result is an engineering milestone and a whole new level of tile and waterline performance. Budget models will only clean pool floors and partial walls. When you invest just a bit more, you get a robot that will actually reach and scrub your waterline for you.

Dolphin Premier Waterline
Dolphin Standard vs NanoFilter™


2 NanoFilters™

You absolutely want a robotic pool cleaner with NanoFilters™. The reason is you may want to capture super fine particles like algae. This fine debris will pass through basic filters. Look for robots that have at least two sets of filtration media: Standard and NanoFilters™. The regular filter is good for larger debris. But if you really want to polish the water or remove algae, you’ll need something much finer than the typical level. Some people have asked us why not just run the NanoFilters™ filters all the time? The reason is that NanoFilters™ filters have a lower flow rate. So if you want to pick up acorns off the bottom of the pool, just swap in the regular filter to maximize the flow rate.

MULTIMEDIA™ specially designed for leaves


3 MultiMedia

What’s even better than having 2 sets of filtration options? How about 3 or 4. There’s only one Dolphin pool cleaner with this feature. Multi-Media™ is a Dolphin Premier exclusive feature. Premier includes Fine, NanoFilters™, and an Oversized Leaf Bag. In addition, you can get disposable filter bags so you can just toss ‘em in the trash when you’re done. You can even subscribe to a service to ship these monthly.

Robotic pool cleaners with multiple filter media let you customize your pool’s cleaning job based on its needs that day. Use an ultra-fine filter to capture smaller particles, use a standard cartridge for a regular clean, use the oversized leaf bag after a storm, and perhaps disposable for the really dirty jobs.

4 Leaf Bag

Struggle with Leaves? The Dolphin Premier's NanoFilters™® gives it, not one, but two Leaf Bag options. Perfect for leaves and small twigs, the Oversized Leaf Bag can handle anything you throw at it.

Want an even easier time cleaning? Try Dolphin Premier's disposable debris bag option. Simply swap out the bag when its time to clean.


5 3 Year Warranty

A pool robot’s warranty is a measure of confidence by the manufacturer. That’s why if you find a budget machine with a shorter warranty. If you’re investing in a quality robot, it’ll have a longer warranty of 3 years. We’re talking at least three years of full coverage. Pool robots work hard daily in harsh chemicals and weather, so don’t take a chance on one without a strong warranty to back up your investment.

6 Don’t Cut the Cord. Get the Cord, Not the Battery.

You absolutely want an electric robotic pool cleaner with a cord. Even the best battery operated units just don’t have enough power to clean a swimming pool for hours per day. The cord means the robot can use more motors. Generally 3-4 and often they are larger DC motors with more power. And with a cable, they can run as long as needed. The problem with battery power is that the small batteries on roots can only power them for 60-90 minutes. Then guess what? You have to fish the robot out of the pool and charge it. This isn’t necessary with corded robot. The robot can automatically turn on each day, all by itself. Based on where battery units are at today, they defeat the purpose of an automatic pool robot.


7 Anti-Tangle Swivel

You absolutely want an automatic pool cleaner with a swivel. Ever tried to untangle 60 feet of knots from a power cord under the hot summer sun? It’s awful, trust us. The anti-tangle swivel eliminates tension from building up in the cord as the robotic pool cleaner roams the pool, keeping tedious knots from forming. Plus, that kind of cord dexterity leads to more efficient cleaning. Dolphin pool cleaners were the first to have 360 degree swivels and they work very well.

Programmable Weekly Timer


8 Weekly Timer

A weekly smart timer is a simple solution to the tedious task of manually starting and stopping your pool robot for every cleaning. However, you’ll find it primarily on higher-end models such as the Dolphin ProLine™. This is a short change by manufacturers, as even moderately priced pool robots in the $700 range should all have a programmable weekly timer. The timer especially comes in handy during pool season when your robot is cleaning more frequently – just set a schedule and let it do its thing.


9 Dual Stabilizers

Some products seem to defy the laws of physics. You would never expect a house cleaning robot to climb up to the top of your wall, but that’s exactly what pool robots can do. To enable a robotic pool cleaner to climb up to and remain at to the hard-to-reach waterline, a pool robot requires a special stabilizer. Typically found on commercial pool cleaning robots, this counter-balance allows a pool robot to remain in position while about 50% of the robot is above the waterline. The unique rotating dual stabilizers are the secret to maintaining position on the upper pool wall. You’ll find just a handful of premium pool robots have the dual stabilizer. These robots will deliver the hardware required to thoroughly clean the upper wall and tile area.

10 No Restocking Fee

There are a lot of robotic cleaner options on the market and not every robot will be perfect for your pool. There are plenty of sellers out there (on Amazon and off) that promise easy returns on a product for just about any reason at all. Knowing you get a refund makes it easier to move forward. But that doesn't mean you won't be hit with a fee. A number of online pool retailers charge "restocking fees" that that are often about 20 percent but can go higher. One unwitting buyer, who was told there would be a restocking fee if he returned a product, wrote to us about the practice. Many are sold on and almost nobody knows about the hidden disclosures. As apart of the Dolphin ProLine™, the Dolphin Premier and other ProLine™ models never have a restocking fee. Buy with confidence and look for “No Restocking Fee”.


Final Tips

Few robotic pool cleaners will tick all of these boxes. You’ll find a few that get really close and others that miss all of them. Three at the top of the list are: Dolphin Sigma, Dolphin Quantum, and Dolphin Premier.

If you don’t remember anything else, remember to avoid robots that are missing too many of these key features: waterline cleaning, multiple filtration options and 3 year warranty. Taking a deep dive into what’s included and what’s not when before you buy.
