1 Is a Corded or Cordless Pool Robot Better?

With battery-operated, cordless pool robots popping up all over the market—mostly from newer, Chinese brands—there’s a lot of buzz about going cordless. The idea of a robot without a tether sounds futuristic and hassle-free, but as of November 2024, we just can’t recommend them. Let’s break down why corded models are still better.

The Battery Tech Isn’t There Yet

Cordless pool robots are appealing at first glance, but here’s the truth. They are severely underpowered. Their flow rates and suction power are no match for corded models with larger, more powerful motors. This means they struggle to pick up fine debris, leaves, and other grime from the pool floor. A corded robot provides consistent power for a deeper and more thorough clean every time.

Worried about a tangled cord? That used to be a big issue—but not anymore. The newer corded models are equipped with 360-degree swivels that prevent tangling altogether.

True Automation or Just More Work?

Let’s talk about what “automatic” really means. Cordless robots sound like the pinnacle of convenience, but they’re actually a lot more work. Their battery life typically lasts only 60-120 minutes, and then they become underwater bricks. This means you’ll be pulling them out of the pool every day, charging them up, and putting them back in. For most pool owners, that daily cycle becomes unbearable.

Corded models allow you to truly “set it and forget it.” Plug it in, drop it in the pool, and let it handle everything while you go about your daily life. You don’t have to think about it. That’s what real automation looks like.

Safety Concerns: The Lithium-Ion Fire Hazard

We can’t overlook the growing safety issues with lithium-ion batteries in pool robots. In recent months, there have been troubling reports of fires linked to overheating batteries in some cordless brands. The Aiper models have been at the center of several alleged incidents involving smoke, sparks, and in some cases, entire homes being damaged or destroyed by fire. When dealing with water and electricity, safety should always come first.

Corded robots, on the other hand, run on continuous power without risky batteries. You can rest assured that the risk of overheating or fire isn’t part of the equation. Plus, you’re getting a pool robot that can handle the workload day in and day out without compromise.

The Cost Factor

Let’s not forget the cost of ownership. Many of these cordless robots are priced to look competitive, but the hidden costs quickly add up. Short battery life means that within a year or two, you might be replacing the battery—or worse, the entire unit. And that’s if you’re lucky enough to avoid any overheating or safety issues.

With a corded model, you get a machine built to last, providing powerful cleaning for years without needing constant maintenance or expensive battery replacements.

What Real Automation Looks Like

At Poolbots, we believe pool robots should simplify your life, not add to your to-do list. The corded models are designed to be dependable workhorses—set them up once, let them do the dirty work, and forget about it until it’s time to take a dip. No daily battery checks, no fear of sudden failures or hazardous overheating—just consistent, powerful cleaning every time.

If you’re considering a pool robot, think about what you’re actually getting. A corded model may have a cord, but it also brings the power, reliability, and true hands-off automation that you want when investing in a pool cleaner. Don’t be fooled by the hype of “cordless freedom”—often, that freedom comes at a cost you don’t want to pay.

2 Safety and ETL Ratings – Protecting Your Home & Family

When it comes to robotic pool cleaners, safety is always priority #1. After all, these are electric devices working underwater, so proper safety certifications are critical. That’s where ETL ratings come in.

What is ETL Certification?

ETL (Electrical Testing Laboratories) certification is a gold standard for safety. It means a product has been independently tested and meets stringent safety standards. If a pool robot has an ETL rating, it’s been through a series of tests to ensure it operates safely in water, resists electrical failures, and minimizes risks to your family and home. Without ETL certification, you’re gambling not just with the product’s reliability but also your family’s safety. That’s why we at Poolbots only recommend ETL-listed robots.

The Lithium-Ion Pool Robot Battery Problem

The market is flooded with uncertified cordless pool robots from new startup factories in China. Nearly all use lithium-ion batteries because they’re cheaper to make. Unfortunately, they often lack the necessary engineering and safety standards, which poses serious risks. While convenient, these batteries come with a significant downside—fire risk.

Reports of overheating and fires, sometimes causing serious home damage, are too common. Lithium-ion batteries can be volatile, especially if not properly protected from water or electrical faults. Due to these concerns, we no longer recommend lithium-ion-powered robots. Plus, corded models are simply more powerful, reliable, and offer true hands-off automation.

Pool Robots & ETL-Certified Safety

ETL certification means every component—power supply, wiring, even battery housing—has passed rigorous safety checks for things like water resistance and overheating protection. Cordless robots might sound hassle-free, but the risks are real. Pool robots should make life easier, not more dangerous. At Poolbots, we recommend ETL-rated corded models for safety, reliability, and better performance without the risks of lithium-ion batteries.

3 Robot Filtration - From Mesh to Nanofiltration

The filter is often the most overlooked part of a pool robot, yet it’s the most critical. After years of testing various filters, we’ve observed that without the right filter, small particulates and algae can easily pass through, leaving your pool less than clean. The most common issue? Green algae. It’s the top contaminant in pool water and often bypasses the so-called "fine" filters many pool robots use.

Filters work by a process called sieving, where the pore size determines what gets trapped and what escapes. Most pool robots still rely on basic, large-pore plastic mesh filters—a leftover from earlier technology. This large-pore filter, common in discount cleaners sold on platforms like Amazon, handles larger debris but lets smaller particles, like algae, pass through.

Why Advanced Filtration Matters

Our experience with basic filters shows they fall short, which is why we focus on advanced filtration systems that go beyond surface-level cleaning. Equipped with the right filter, you get crystal-clear and polished water. We ensure your pool robot is ready for real-world performance, not outdated tech.

---

NanoFilter™: High-Efficiency Filtration for Your Pool

We’ve tested every type of filter available, and not all are created equal. First-gen filters were simple mesh screens that didn’t catch small particles. That’s where NanoFiltration shines. Think of NanoFilter™ as a HEPA filter for your pool, capturing fine dirt and debris that standard filters miss, providing a deeper clean you’ll quickly notice.

Micro-Pore Innovation—What Makes NanoFilter™ Stand Out

The NanoFilter™ utilizes high-efficiency particulate filtration that keeps contaminants from recirculating in your pool water. The micro-pore, spun-bonded polyester fabric forms an intricate web to trap fine particles. Real-world testing showed the deep pleats in NanoFilter™ hold a surprising amount of debris—stuff you might not expect to find in your pool. The pleated design also increases surface area, capturing more particles while maintaining low water resistance for optimal cleaning.

Turbidity Has Met Its Match

For reducing turbidity, pleated filters outperform non-pleated ones. Nanofiltration captures virtually everything: leaves, sediment, insects, pollen, algae, pet dander, and microscopic debris. With a larger surface area to handle higher contaminant volumes, these filters deliver the crystal-clear, polished look every pool owner desires. Pools using NanoFilter™ technology consistently stay clearer and cleaner, with reduced chemical needs.

The Science of Clean—More Than Just Filtration

NanoFilter™ technology does more than just trap particles. We observed another key advantage—polyester’s natural ability to absorb oil. NanoFilters™ capture contaminants like sunscreen and natural body oils, preventing slicks and scum lines. When it’s time to clean, these trapped oils wash away easily, leaving your water clear and inviting. Our testing showed significantly improved water quality and unmatched surface clarity.

Boost Your Pool’s Water Quality with NanoFilters™

A clean pool starts with the right tools, and NanoFiltration is a game-changer. Acting as a booster for overall water quality, it removes contaminants before they reach your pool’s main filtration system. After extensive testing, we confidently recommend NanoFilters™ for every pool owner. For crystal-clear water and a polished look, NanoFilter™ is the tool of choice.

Go Big with MaxBin Filters

The Max-Series: Easier Cleaning with MaxBin®

We know what makes a robotic pool cleaner stand out because we’ve extensively tested them all. The Max-Series is unique, with MaxBin® as a second-generation upgrade that redefined pool filtration. The game-changer? A completely redesigned filter that replaces twin, small filters with a massive, top-loading debris bin.

Designed with You in Mind

MaxBin® was created in response to real pool owner frustrations. Older models, like the Dolphin Nautilus CC Plus, used two small filters with six separate parts. Each cleaning session required disassembling each piece—tedious and time-consuming. MaxBin® solves this problem.

With MaxBin®, there’s no need for disassembly. This next-gen design cuts cleaning time by 80%. Instead of six touchpoints, there’s just one, making emptying the bin easy and less messy.

100% Larger Bin. 200% Easier to Clean.

Cleaning a Max-Series robot is incredibly simple. The top-loading design lets you lift the panel, grab the handle, and dump the debris—no hassle, no mess, no dirty hands. In our hands-on tests, it takes only seconds, a significant convenience improvement over previous models.

Before MaxBin®, users had to open, rinse, and spray two small cartridges, each with multiple parts—a time-consuming process. Now, a simple trap door and one quick motion make pool cleaning a breeze. Flip open the bin, give it a quick spray to remove any fine debris, and you’re done.

As Simple as It Should Be

The Max-Series, found in models like the Dolphin Escape, Dolphin Cayman, and Dolphin Quantum, makes cleaning fast, easy, and frustration-free. After hours of testing different models, we can confirm this one finally hits the mark.

Multi-Media®: Best of Both Worlds

Are you looking for a robotic pool cleaner with different micron levels of filtration to capture the finest particles, like algae? Or do you need to pick up leaves and acorns? You can now buy pool robots with one type of filter, two types of filters, three types and now even four types. This is important because different jobs call for different micron ratings. Smaller micron filters are great for fine debris, but not so great for picking up acorns a leaves. This is because the small micron rating will have a lower flow rate, and provide less suction power.

In the past, you typically had to choose between two types of filtration: cartridge or bag. Each of these systems were much better at serving one purpose than the other. Some user find that cartridges are a bit easier to clean than non-disposable leaf and debris bags, but are quite a bit smaller than the debris bags so you had to make a compromise. With the flexible 4-in-1 Multi-Media® system, this is no longer the case. Plus, disposable leaf & debris bags are available (more in next section).

There only one model that offer Multi-Media, so we’ll cover it – the Dolphin Premier. No other pool cleaner offers the same level of choice as Dolphin’s flagship, the Dolphin Premier. Featuring three sets of filtration media—Fine, NanoFilters, and a Leaf Bag — You’ll be able to easily customize your pool cleaning experience for whatever the day calls for.

Need to Pick up a Bushel of Leaves? Go Leaf Bag.

Tired of struggling with leaves and other large debris? The leaf bag is perfect for leaves, twigs, and other small debris. There are now two types of leaf bags, reusable and disposable. This innovative feature allows you to quickly and easily swap out the bag when it's time. Dolphin Premier's Multi-Media® makes it easier than ever to keep your outdoor living space clean and beautiful.

Tired of Washing the Filter? Go Disposable

For the first time ever, you can choose disposable leaf and debris bags that can be thrown away when you’re done. Have a nasty spring clean-up job? Simply toss the disposable bag in the trash and skip the cleaning at the end. Plus, you can even subscribe to a service and have these bags delivered to your door each month. The Dolphin Premier with Multi-Media® is the only pool cleaner out there with such a selection of filtration options.

4 Set & forget with automation. How a weekly smart timer boosts satisfaction.

The Automation Gap: Why Some Pool Robots Are Still Way Behind

When it comes to true automation, many pool robots sold on the major online platforms leave much to be desired. We frequently hear from customers who are frustrated by having to manually start their pool cleaner for every single use. In 2024, it’s surprising—and disappointing—that many so-called "automatic" robots still lack a basic feature like a weekly timer. It’s like to buying an "automatic" sprinkler system that still requires you to remember to turn it on.

This lack of automation becomes even more inconvenient during peak pool season when frequent cleaning is a must. Manually managing a pool robot can quickly become a hassle, especially when it’s supposed to be a hands-off solution. Most mid-level and premium models include a convenient weekly timer—allowing you to press a button once, set your desired cleaning schedule, and let the robot handle the rest. This is what real automation should look like.

The Benefits of a Smart Weekly Timer

A built-in timer elevates a pool robot from a manual device to a true hands-free assistant. With an automated schedule, you can set your robot to clean daily or on specific days throughout the week. This means no more worrying about whether you remembered to turn it on or dealing with the inconvenience of starting and stopping each cleaning cycle. A smart timer ensures your pool remains clean and swim-ready without requiring your constant attention.

It’s hard to believe that people are still buying pool robots without timers from the big online platforms. The low price draws them in, but most buyers don’t realize what they’re missing until they plug it in and have to deal with the daily chore of manually starting their robot. We’re in a unique position because we get these calls every day. Customers reach out, frustrated, because what they thought would be a “automatic” solution quickly turns into another task on their daily to-do list. They ultimately realize that true automation means more than just having a robot. It means having one that can handle cleaning on a schedule without constant human intervention.

5 Why Waterline Scrubbing is Important

The waterline is often the most neglected—and dirtiest—part of any pool. Our dedicated test tanks have shown that this is where oils, sunscreen, and debris like to accumulate, leaving behind that dreaded scum line that’s a pain to remove with weekly scrubbing. The top robotic pool cleaners are up to the challenge.

After testing hundreds of models, we’ve learned that only leading robotic pool cleaners come equipped with dual stabilizers, allowing them to traverse the waterline horizontally and scrub away buildup like never before. If you’ve never seen it in action, it’s a game-changer. These specialized robots navigate seamlessly from the pool floor to the very top of the wall, scrubbing every inch—including the notorious scum line.

From our testing, we can tell you that the magic lies in the dual stabilizers. These stabilizers allow the robot to cling firmly to the pool wall even when up to 40% of the unit is above the waterline. This stability lets the robot aggressively scrub away bacteria, algae, and biofilm—quickly and effectively—resulting in a pool that’s clean from top to bottom. This is a major contrast from most of the robots found on Amazon which focus on pool floor cleaning.

6 Why a 360-Degree Anti-Tangle Swivel Is a Game-Changer for Robotic Pool Cleaners

A 360-degree anti-tangle swivel opens up the door to superior performance by allowing you to choose a corded pool robot with bigger motors and more suction power. We’ve talked to countless customers who initially thought a battery-operated cleaner might be the perfect solution. After all, the idea of a cordless pool robot sounds convenient and hassle-free. But here's the reality: battery-operated models are simply not up to the task.

The main issue with battery-operated pool robots is their low power output. With smaller motors, they lack the suction power needed for a thorough clean. In fact, they can’t even make it through a single 3 hour cleaning cycle in most cases. Battery models fall short in terms of automation.

Unlike corded cleaners, they can't turn on automatically on a set schedule. This is because their batteries die after just 1 to 2 hours of use. So instead of enjoying the convenience of automation, you get stuck with a daily routine of charging and manually deploying your robot. It’s a real pain that few buyer expect.

A corded pool cleaner equipped with a 360-degree anti-tangle swivel solves these problems. Not only do you get the increased power and superior cleaning capability of a larger motor, but you also get true automation, with the cleaner running on a schedule without needing constant attention.

The swivel keeps the power cord from tangling, allowing the robot to move freely and clean the entire pool without interruption. A corded cleaner with a swivel is the best of all worlds. You get maximum power, the convenience of a fully automated system, and none of the headaches of untangling cords or recharging batteries.

One of the best-kept secrets in the pool robot industry is that you can enjoy commercial-grade performance and durability in a residential pool cleaner—without paying commercial prices. Dolphin’s commercial models, like the Wave 75 and Wave 80, are engineered specifically for demanding environments such as hotels, schools, and swim facilities. These robust machines handle the heavy workloads of large pools with ease, thanks to high-capacity filtration, powerful motors, and advanced navigation. But here’s the exciting part. Several residential Dolphin models are built on the same powerful platforms as these commercial cleaners, giving homeowners access to professional-grade performance in their own backyards.

Discovering the Commercial Power in Residential Models

Dolphin’s commercial robots are designed to meet the rigorous needs of high-use pools, where performance and reliability are non-negotiable. Take the Dolphin Wave 75, for example—built to be a fully automated cleaning powerhouse for high-traffic pools in hotels, campgrounds, and schools. Equipped with advanced scanning and navigation, the Wave 75 systematically cleans every inch of the pool’s floor, walls, and waterline, effortlessly avoiding obstacles to maintain pristine, hygienic water after each cleaning cycle.

What’s remarkable is that Dolphin has brought this same commercial-grade power into some of their residential models. These “hidden gem” residential robots share the same core technology, high-capacity filtration systems, and powerful motors as the commercial models—but at a fraction of the price. The Dolphin Premier and Dolphin Sigma are two standout residential models that use the same platforms as the Wave 75 and Wave 80, respectively, allowing you to get near-commercial performance at a much more accessible cost.

Built to Last: Longevity and Durability That Set Them Apart

Durability is one of the key benefits of these premium residential models. Dolphin’s commercial-grade robots are built to withstand heavy use, and that same level of robustness carries over to these residential units.

8 How much warranty is enough?

As long-time specialists and sellers of pool robots, we've noticed a trend. Robots built on commercial-grade platforms with three-year warranties simply last longer. In fact, we talk to customers with robots that are over 10 years old and still running strong. This kind of durability speaks volumes about the quality and reliability that comes with investing in a well-built, warranty-backed robot.

Pool robots work tirelessly, day in and day out, in challenging conditions—exposed to harsh chemicals, extreme temperatures, and constant water exposure. We know from experience that these conditions can wear down components over the years. That’s exactly why a longer warranty is so important. A comprehensive three-year warranty gives you the assurance that, if anything goes wrong, you will avoid out of pocket repairs.

9 Why Dual Stabilizers Make All the Difference in Pool Robots

If you’re in the market for a pool robot, you may be surprised to see that some models appear to defy the laws of physics. Imagine your household cleaning robot suddenly scaling the walls—sounds impossible, right? Thankfully, this technology is real. These pool robots climb to the top of your pool wall and stay there, moving horizontally across the waterline. This impressive ability comes down to the special stabilizers found on commercial-grade pool robots and select premium consumer models.

The key lies in the rotating dual stabilizers, which are featured on units built on the commercial platform, such as the Dolphin Premier and Sigma. These stabilizers serve as a counter-balance, enabling the robot to stay in position even when half of it is above the waterline. This stability allows the robot to effectively clean the upper walls and tiles, eliminating stubborn debris, algae, and the hard to reach scum line that other models miss completely.

We’ve seen firsthand that robots equipped with dual stabilizers provide significantly better cleaning performance. They can tackle not just the pool floor but also the walls and waterline—areas where dirt and grime tend to accumulate. If you’re serious about keeping your pool in top condition, look for a model with dual stabilizers. It’s a feature that sets the best robots apart and delivers a level of clean that others simply can’t match.

10 Unraveling the Flood of Platform Seller Fake Online Reviews and Chinese Junk

We’ve seen firsthand how difficult it can be for consumers to separate quality products from low-grade, unreliable junk. The rise in popularity of pool robots has brought a flood of models to the market, many produced by sellers leveraging fake reviews and deceptive tactics. Among these models, some may look appealing on the surface, but there are many reasons to be cautious—especially with Chinese-manufactured units and their inflated ratings. Let’s pull back the curtain on what’s really happening.

The Truth Behind the Fake Reviews

If you’ve shopped for a robotic pool cleaner online, you’ve likely come across dozens of models boasting 4 to 4.5-star ratings. At first glance, these ratings might seem like a reassuring green light to click "buy." But as experts who have tested over 70 different models in our test tanks, we’ve seen how misleading these high ratings can be—especially with certain overseas brands.

Using tools like Fakespot, a tool developed by Mozilla that analyzes online reviews for authenticity, we’ve found that many highly-rated pool robots are far from reliable. For example, Aiper has received an “F” rating from Fakespot, indicating a high level of deception in its reviews. These ratings are often inflated through practices such as review wiping—a tactic where sellers take down a product listing when it starts accumulating negative reviews, only to relaunch it under a new listing. This allows them to effectively "wipe away" criticism and start fresh, leaving unsuspecting buyers in the dark about the product’s true performance.

Free Products for Reviews: The Vine Effect

Another common tactic we’ve observed is the use of Amazon’s Vine program, where products are provided for free in exchange for reviews. While this might seem harmless, it creates a flood of positive, often superficial reviews, making low-quality products appear highly rated. This strategy misleads consumers into thinking they’re purchasing a top-tier pool robot, only to find themselves dealing with a host of problems once the unit is in their backyard.

Safety Concerns with Low-Quality Batteries

Beyond misleading reviews, some of these low-cost robots pose serious safety concerns. Based on numerous consumer reports, we’ve seen multiple incidents involving lithium-ion battery fires in cordless models manufactured in China. Videos online show houses catching fire and pets needing emergency care after these batteries allegedly malfunctioned. The risk is simply too high for a product designed to operate in water, and unfortunately, many consumers aren’t aware of these dangers until it’s too late.

To date, we have yet to find a cordless pool robot at this price point that is ETL Listed and delivers both safety and performance. While cordless models might seem like a convenient solution to avoid cord tangling, their weak battery life, low power, and high failure rate make them a poor choice for anyone seeking a reliable cleaning solution.

The Bottom Line: Why It Pays to Choose Proven Brands

At the end of the day, the flood of cheap pool robots on major online platforms, paired with fake reviews and deceptive listings, makes it challenging for the average consumer to navigate the market. Investing in a well-built, safe, ETL Listed corded pool robot with modern features like a 360-degree swivel, powerful motors, strong suction, and effective filtration is the best way to ensure you get a product that truly performs.

Don’t be misled by high ratings and low prices. There’s a reason these units come and go so quickly. Stick with brands that stand behind their products, provide meaningful warranties, and have earned their reputation through real performance—not just glowing reviews given in exchange for free products.

11 Robot Color Is More Important Than You Think

One would think that color of pool the robot doesn’t matter much. This is true, except for one color. Black. There have been reports of black pool robots leaving scuff marks on gunite, plaster and fiberglass swimming pool surfaces. The plaster is abrasive and the black plastic is removed and deposited into the plaster surface. Reports indicate that the black can be difficult to remove. The solution is simple - choose any color but black.

It turns out that black-colored plastic gets the color from carbon black pigment. This seems to be the issue as scuff marks have not been reported on other colors such as grey, blue or white. For this reason, we highly recommend choosing a robot that is grey, blue, white or some combination of those colors.

12 Avoid the Restocking Fee: Check Before You Buy

Finding the right robotic cleaner might require trying out a few in your own pool. Unfortunately, many online retailers are well aware of this and are not eager to return the money you’ve handed over. They may advertise “easy returns,” but often hide hefty restocking fees in the fine print.

Many customers share the same story with us: after deciding to return their pool robot, they were hit with a 20% restocking fee—something they never saw coming. This is why it’s so important to look for a “No Restocking Fee” policy when shopping for pool cleaners.

While Amazon is a popular choice for buying pool robots, it's crucial to understand what you're getting into. Many of the discount pool robots sold on Amazon carry a 20% restocking fee, meaning that if the robot doesn’t work for you, returning it could cost you hundreds of dollars. Don’t let yourself fall victim to these hidden fees.

To avoid this, seek out the retailers who stand behind their products and offer transparent, customer-friendly return policies without hidden fees. By looking for a "No Restocking Fee" guarantee, you can shop with confidence, knowing you won’t be hit surprise costs if the robot doesn’t meet your needs. Make sure your pool robot purchase is backed by a trustworthy dealer who puts customer satisfaction first.

Our Honest Take of Aiper: A Risky, Unproven Pool Cleaner Brand

As robotic pool cleaners grow in popularity, Aiper has gained attention—but not for the right reasons. After extensive testing and alleged fires, we have serious concerns about Aiper’s safety and performance. This makes them a risky choice for pool owners. Their cordless models have faced allegations of being fire hazards, reportedly due to faulty lithium-ion batteries. Disturbing claims and videos online even show houses catching fire, with pets needing emergency care. These incidents highlight the potential dangers of choosing an unproven brand like Aiper.

Aiper’s reputation is further tarnished by a pattern of alleged review manipulation, including heavy use of offering free products in exchange for positive reviews and frequent relaunches under new listings. This practice raises significant questions about the brand’s credibility, and Fakespot has rated Aiper with an “F” for high deception.

When it comes to performance, our hands-on testing shows that Aiper’s models fall far short of expectations. The battery life is often disappointing, with some units struggling to last over an hour. Frequent recharging turns what should be a hands-free experience into a tedious daily chore. We have found the cleaners themselves have inadequate filtration and limited coverage, frequently missing debris and failing to clean critical areas like walls and waterlines. Despite their "automatic" label, Aiper’s cleaners lack real automation, forcing users to manually start them each day—an inconvenience that defeats the purpose of owning a robotic cleaner in the first place.

Customer feedback also highlights issues with Aiper’s support. Users often report broken components and slow response times when seeking assistance or replacement parts. Combined with subpar build quality, this lack of reliable support leaves many customers frustrated. Considering these persistent issues, it’s difficult to justify choosing Aiper over more established, dependable brands.

Our Honest Take on Polaris: A Brand Once Dominant, Now Struggling to Keep Pace

Polaris has long been a name associated with pool cleaning, and over the years, we’ve had their models in our test tanks to see how they perform. In the past, when high-horsepower booster pumps were standard, Polaris did a decent job of picking up large debris like leaves. However, this came with a significant trade-off—high energy consumption and added wear and tear on pool equipment. Booster pumps often draw over 700 watts of power, driving up utility bills and requiring frequent maintenance, making them less appealing as the industry shifts toward energy-efficient solutions.

In our tests, Polaris’s traditional pressure and suction-side cleaners have fallen short when compared to modern robotic models. Pressure-side cleaners rely on separate booster pumps, while suction-side cleaners clog filters and reduce their lifespan. This added inconvenience makes them less attractive for today’s pool owners, who are seeking low-maintenance solutions.

Polaris also struggles in other key areas. Unlike premium brands that feature advanced pleated nanofiltration to capture fine particles like pollen and algae, Polaris cleaners typically use standard filters that often leave smaller debris behind—requiring additional manual cleaning. Additionally, many Polaris robots still rely on wheels rather than tracks, limiting their ability to clean vertical surfaces and reach the waterline effectively. Competing brands that use track-based designs consistently performed better in our tests, providing superior coverage and cleaning efficiency.

Warranty coverage is another area where Polaris falls behind. Traditional models only come with a one-year warranty, and robotic units max out at two years. In contrast, top brands like Dolphin offer up to a three-year warranty. While we continue to test new Polaris models as they hit the market, they have yet to match the performance, efficiency, and reliability that today’s leading robotic cleaners offer.

Premium Picks

Dolphin Premier

At the Top of Our List: The Unbeatable Dolphin Premier

You simply cannot beat the Premier’s incredible value. Rated the Best Pool Robot for 2024 by USA Today, the Dolphin Premier is a favorite among pool owners across the nation. It’s no surprise it’s the #1 selling premium pool robot. As the only Dolphin equipped with MultiMedia™ filtration, a dedicated Leaf Bag, ProLine™ Commercial Grade Motors, and the coveted NanoFiltration™ set, the Premier truly performs like a commercial-grade cleaner. In fact, it shares most of its components with the commercial Wave 75, a unit that retails for around $2,500.

The Dolphin Premier: Commercial-Grade Power for Home Pools

The Dolphin Premier, built on the same platform as the Wave 75, brings high-performance cleaning power to residential pools. Owners have seen robots of this caliber last over a decade with minimal maintenance, thanks to robust construction and reliable engineering. With advanced scanning and navigation systems, the Premier ensures systematic cleaning of your pool’s floor, walls, and waterline, capturing fine dirt, dust, and debris for crystal-clear water after every cycle.

Remarkably, the Premier even surpasses the Wave 75 in residential warranty, offering up to three years of coverage, compared to the commercial model’s shorter warranty. And here’s the kicker: the Premier is priced over a thousand dollars less than the Wave 75, making it a fantastic deal for homeowners who want commercial-level performance without the commercial price. Equipped with NanoFiltration™, the Premier effortlessly captures microscopic particles as it glides along the waterline, keeping the dirtiest parts of your pool clean and clear.

Easy to Use: Plug-and-Play Simplicity

The Premier is built for ease of use, featuring Automation Plus with a Programmable Weekly Smart Timer and a MediaAlert™ Full Filter indicator. Just drop it in, turn it on, and let it clean—no complicated setup required. As Maytronics' flagship cleaner, the Premier includes a three-year warranty, ensuring peace of mind for your investment in pool maintenance.

MultiMedia™ Filtration System

The Dolphin Premier’s standout feature is its MultiMedia™ Filtration System, offering four filtration options (three of which are included). This system includes Dolphin's Standard Mesh Filter and the advanced NanoFilters™, which are a game-changer. Just like in the Dolphin Sigma, we loved how the NanoFilters cleaned deeper than any other filter system. Only available in select ProLine™ and Max-Series™ models, these filters have a pleated design that captures more impurities, leaving your water remarkably clear.

The Exclusive Oversized Leaf Bag

With its exclusive oversized leaf bag, the Premier is unmatched in leaf collection, picking up large debris that other cleaners miss. With a three-year warranty—50% longer than standard models—the Premier is a top choice among the 2024 robotic pool cleaner models.

Long-Term Reliability

Built on a commercial platform, the Dolphin Premier is designed for long-term durability. Our testing confirmed it: the Premier performed consistently well, day in and day out, thanks to its ProLine™ Commercial Grade Motors.

It offers advanced app functionality, including Siri voice control through the myDolphin Plus app. You’ll have access to remote control, pool history and stats, and advanced weekly scheduling options right from your phone. Though controls on the power supply are sacrificed, the app’s extensive features offer true flexibility.

Note: For those who prefer non-app controls, the Dolphin Premier retains power supply controls, offering a more traditional setup. However, if seamless app connectivity and remote control are appealing, the Sigma is a perfect choice. Just plug it in, connect to Wi-Fi, and watch it work—no extra equipment or setup is needed.
