Cleaning a swimming pool ranks right up there with scrubbing bathroom floors, but the consequences of neglecting either chore are equally unhealthy. Fortunately, living in the age of robots means you can ditch the laborious chores of manually skimming leaves from your pool’s surface and scrubbing algae from its walls and floors.
Invest in a modern robotic pool cleaner and let that machine do that dirty work for you. (Sadly, we’ve yet to find a robot that can scrub toilets.)
These labor-saving pool bots come in various shapes and sizes with diverse capabilities, not to mention a wide array of prices. The most sophisticated models go for $2,000 or more. Here are our top picks, followed by a buyers’ guide that will help you determine what you need in a robotic pool cleaner.
Polaris Freedom Plus – Best cordless robotic pool cleaner overall
Pros
- Overall great cleaning quality
- Lightweight, drains water quickly
- Docks at waterline for easy retrieval
Cons
- Slightly less effective than Polaris’ corded model VRX iQ+
- Remote control is somewhat difficult to use
- Very expensive

Who should buy the Polaris Freedom Plus?
The Polaris Freedom Plus is a great choice for homeowners with larger pools who want hands-off cleaning with the option to remotely control their pool-cleaning bot to ensure specific areas are cleaned.
Polaris’s premiere battery-powered pool robot wins on flexibility, even if it makes minor compromises in cleaning prowess compared to its corded–and much less convenient to use–cousin, the Polaris VRX iQ+ (our pick for the best corded robotic pool cleaner). This bot has a large, easy-to-clean debris basket, and it was extremely effective at removing leaves and other debris from our test swimming pool.
Polaris Freedom Plus: Further considerations
This pool cleaner comes with a ton of great convenience features. When the bot has finished its work, it automatically parks itself at the side of the pool for easy retrieval. It even comes with a caddy that provides contactless charging, and its 20-pound weight makes it easy to move from the caddy to the pool when it’s time to clean.
At $1,699, the Polaris Freedom Plus is pretty expensive and while it is the best, those on a budget might find less expensive options without the bells and whistles that still do a decent job.

Who should buy the Beatbot Aquasense Pro?
Pool owners looking for the ultimate in programmability and flexibility in cleaning should take a long look at the Aquasense Pro. This machine is outfitted with nine separate motors, which help it cruise around your pool with focus and efficiency.
It has four Four preset cleaning modes: floor only; floor, wall, and waterline; floor, wall, waterline, and surface; and an eco mode that cleans the pool’s floor once every other day until its battery dies. But you can also create custom cleaning modes for the floor, walls, and surface that give you more than 20 other ways to keep your pool spotless.
Beatbot Aquasense Pro: Further considerations
Like many robot vacuums, the Aquasense Pro comes with a docking station that automatically charges its battery, eliminating the need to drag a power cord to the device after each cleaning session. It will clean your pool’s floor, walls, waterline, and the water’s surface. It does a great job vacuuming up dirt and debris from the bottom of the pool, trapping it in its two-piece mesh basket. And if you opt in to purchasing its water-clarifying agent, the robot will dispense it while it moves around sucking in leaves off the surface of the pool.

Who should buy the Wybot S2?
If you’ve been maintaining a large swimming pool the old-fashioned way, you’ll love the labor savings the Wybot S2 will deliver. Its large battery will ensure the pool is always clean and ready for use.
Boasting the ability to clean swimming pools measuring up to 3,230 square feet and equipped with a beefy 7800mAh battery, the Wybot S2 can scrub nearly any pool in just a few hours. And its ability to suck up debris is as good as its ability to scrub, thanks to a large basket with two filters, the second of which is great for capturing fine-grained grit.
Wybot S2: Further considerations
This robotic pool cleaner is outstanding in every other regard. If price is no object, however, the Polaris Freedom Plus is even better; that said, it’s also nearly twice as expensive. Be prepared to endure some quirks in its app–it seems it could have used a wee bit more polishing before it was released–but that software should be relatively easy to update.
Also, don’t let its idiosyncratic navigation fool you. It might look like it’s wandering around with no clear purpose, but it will leave no area of your pool’s floor, walls, and waterline untouched.

Who should buy the Fanttik Aero X?
Those who have extra large pools or pools prone to high volumes of debris to clean up will find that the Aero X is a more than capable cleaner. It might look more like a lawn mower than a pool cleaner, but don’t let that throw you off.
This robotic pool cleaner is an underwater monster that runs fast and runs long: With six hours of running time and top-notch cleaning power, the device makes short work of underwater debris. The long battery life and large basket mean that it merits consideration for even larger commercial or public pools.
Fanttik Aero X: Further considerations
The Fanttik Aero X certainly isn’t the least-expensive robotic pool cleaner on the market, but if you’re looking after a large pool and need a bot with long battery life, this is an excellent choice.
While the Aero X works just fine on its own, the fantastic remote control makes it into a big toy for adults. A centerpiece joystick gives you full, real-time, responsive control which is a rarity among manually controlled pool cleaners—plus, it makes it feel like a remote-controlled car which is just a joy to toy-around with.

Aiper Seagull SE – Best robotic pool cleaner for smaller pools
Pros
- Very easy to use
- Lightweight, sleek, and fast
- Reasonably effective at cleaning considering the price
Cons
- Failed to park itself near the wall at end of its cycle
- Struggles with larger leaves
- Requires significant regular maintenance

Who should buy the Aiper Seagull SE?
Aiper’s entry-level pool bot is best for people with smaller swimming pools—up to about 850 square feet. If you’re working with a tight budget, you could try deploying one in a larger pool, but be aware that its battery will need multiple charging cycles to get the entire job done.
If your pool is on the small side, Aiper’s entry-level pool bot should have no trouble cleaning debris from it. It lacks much in the way of features beyond its on/off switch, but it’s a capable and incredibly low-cost choice if all you need is occasional help scooping up leaves that you’d otherwise have to collect by hand. Additionally, it makes for a handy second pool cleaner if there isn’t enough debris to warrant pulling out a larger cleaner and you just want to quickly tidy up a bit.
Aiper Seagull SE: Further considerations
The 8-pound device is easy to maneuver, zooming around the pool for about 90 minutes before its battery dies out.
The Seagull SE is also a much cheaper alternative to many robotic cleaners, but it comes with the caveat that you’ll need to perform daily maintenance instead of the more lax weekly requirements of larger models.

Polaris VRX iQ+ – Best corded robotic pool cleaner
Pros
- Best performance of any pool cleaning robot we’ve tested to date
- Optimizes run time based on pool size
- Lift system lets you retrieve the robot on demand without a pole
Cons
- Very expensive
- Wrangling power cable requires some extra effort
- A bit of an eyesore even when not in use

Who should buy the Polaris VRX iQ+?
If you’re looking for the most effective robotic pool cleaner, and you have a place to stash it and its bulky caddy when it’s not in use, and you don’t mind wrestling with its power cord each time you set it to cleaning–and again when it’s done its job–the Polaris VRX iQ+ is hard to beat. If those chores are a turn-off, pick one of our battery-powered recommendations instead.
Still, what it lacks in portability, it makes up for in performance: The Polaris VRX iQ+ provides the most effective cleaning of any robotic pool cleaner we’ve ever tested—leaving the large-sized pool we used for the review absolutely spotless.
Polaris VRX iQ+: Further considerations
The Polaris VRX iQ+ differs from the other robotic pool cleaners we’ve tested by virtue of the 70-foot insulated power cord that connects it to its out-of-the-water control panel. Wrangling the cord can be a chore–and it’s not the least bit attractive whether the robot is in use or not.
Also, it is quite expensive. But just remember that you’re paying for unrivaled performance.

Who should buy the Wybot F1 pool skimmer?
The Wybot F1 pool skimmer is much more effective at capturing floating leaves and debris than any other skimmer we’ve tested—about 85 percent of the leaves; the remainder had already sunk to the bottom.
While I don’t typically recommend pool skimmers as their performance is almost always inferior to a full cleaner, the Wybot is an exception. Not only is it vastly cheaper than a full robotic pool cleaner, but it’s effective enough that you might not notice a difference. Users who are diligent about running a skimmer right after a storm or windy day will likely find that the Wybot is a worthy alternative.
Wybot F1 pool skimmer: Further considerations
The F1 is a solar-powered skimmer meaning you don’t need to worry about stopping mid-session to recharge the batteries—so long as there’s enough sun to do the job.
It’s also worth noting that the Wybot F1 is quite loud when operational. This is mostly down to the impellers that allow it to scoot along quickly around the pool, but also make it sound like an actual boat.

Other robotic pool cleaners we like
While we believe that the pool cleaners above are the best that money can buy, if none of those tick all of your boxes, there are a few other products that might: The Airrobo PC10‘s price is this robotic pool cleaner’s primary attraction. It’s certainly not the most powerful bot we’ve dropped in the pool, but it is one of more affordable mid-range models. The Dreame Z1 Pro took a few firmware updates for us to be mostly satisfied with this pool cleaner, which is more intelligent than most. The Ofuzzi Cyber 1200 Pro won’t clean your pool’s walls, but we found that it did a great job vacuuming up leaves and other debris from the bottom of our pool. It’s attractively priced, too. And the Seauto Shark excels at picking up dirt and grime from the bottom of the pool, but in our test runs, it tended to miss key sections.
How I test pool cleaners
I test robotic pool cleaners in two ways: First, I start with real-world tests by letting debris build up for a few days, I then drop the robot into the water to see how it fares. This isn’t scientific—and it’s seasonally dependent on falling leaves—so I also devised a synthetic test using about 100 craft leaves made from silk. These I scatter across the pool before initiating a standard cleaning run. Measuring the portion of leaves left behind makes it easy to make an apples-to-apples comparison among various robots’ cleaning capabilities.
TechHive has not tested any robot pool cleaners in an above-ground pool.
Why you should trust me
I’ve been in and around home swimming pools for most of my life, and I have owned my own pool since 2022. The pool is actively used, and I perform some level of maintenance on the pool nearly every day. I have tested a variety of cleaning devices in the pool, including old-school water-powered Polaris cleaners and a number of more modern robots. The pool depth ranges from about 4- to 7-feet deep and is L-shaped, measuring 12×36 feet, with a small leg jutting out that adds another 6×6 feet in the shallow end, totaling 468 square feet.

How to choose a robotic pool cleaner
As with most tech products, the feature sets and capabilities of pool-cleaning robots advance as their price tags go up. Here’s a partial list of features that you should look for, sorted from the most common—and therefore should be present on even the least-expensive models—to the fancier features you’ll find on the more sophisticated, and pricier, models.
Battery life/square footage
These specs go hand in hand: The larger the battery, the more area the robot should be able to cover. In my experience, most manufacturers exaggerate how many square feet their bots can cover on a single battery charge. Look for a model that promises coverage of at least twice the size of your pool’s square footage.
Mobile app support
Starting at about the $1,000 price range, robotic pool cleaners start to include Wi-Fi connectivity and mobile app support. These features lets you monitor battery life and the robot’s cleaning mode, and—at least in theory—map your pool visually. These features don’t always work as planned, but it can be helpful to get a push notification on your smartphone if the robot gets stuck somewhere.
Remote control
A few robots include a standalone remote control that let you “drive” the robot toward debris or tell it to abort its cleaning run altogether.
Self-parking
Many robots can park themselves near a wall at the bottom of the pool when they’re finished running, which makes them easier to retrieve with a pole (a hook attachment is always included). I’ve found this feature to be hit-or-miss affair with the inexpensive models, while the more advanced ones can rise to the surface of the pool and float there. At that point, you can simply pull them out of the water by hand, no tools needed.
Surface-cleaning capabilities
Beatbot
Want a robot that can skim leaves that haven’t yet sunk to the floor? Look for a model with a skimming feature–although note that these won’t provide perfect coverage due to the tendency of leaves to migrate while the robot is in motion.
Wall-cleaning capabilities
Christopher Null/Foundry
I didn’t think I needed this feature until I tried it out: Who gets debris on the walls of the pool? Well, you do, more than likely. Wall-cleaning robots can physically scrub off algae that you’d otherwise need to do manually, with a brush—and that’s a terribly painful, back-breaking task. The best models use spinning treads, while cheaper robots rely on just suction power.
Best robotic pool cleaners FAQ
1.
What is the best robotic pool cleaner?
The Polaris VRX iQ+ is most reliable and effective pool cleaner we’ve tested to date. It’s speedy, thorough, and easy to use. Its reliability is due in large part to it being corded, and thus free from the limitations of a battery. The best cordless robotic pool cleaner is the Polaris Freedom Plus. It’s slightly less effective than its VRX iQ sibling at cleaning, but still does an admirable job, is packed with features, and eliminates having to wrestle with an unwieldy and unsightly power cord.
2.
How do robotic pool cleaners work?
Robotic pool cleaners are in many ways the watery analogue of robot vacuum cleaners, although their navigational technologies vary considerably. Simple cleaners will use water jets to move back and forth in wide arcs, reversing each time they hit an obstacle while sucking up debris through a small port in the bottom of the robot.
More advanced cleaners have multiple mechanical motors and sensors that take the robot through a more ordered cleaning routine, moving back and forth across the pool like a person behind a lawnmower. Models that can clean the sides of a pool can climb its walls in the same type of pattern. The spinning brushes on these models are more effective at scooping up sand, dirt, and other fine debris.
3.
How do you control a robotic pool cleaner?
For the most part, you don’t. Robot pool cleaners are a “set and forget” affair, though more luxe models can be set to clean the floor only, walls only, both floor and walls, and so on. If you want to stop the robot mid-run, you can grab it with a hooked pole and turn it off manually or with a remote control if one was provided.
Note that mobile apps usually won’t work while the robot is in the pool, as the water and concrete tend to block the wireless signal.
4.
How effective are robotic pool cleaners?
If you’re used to having something like an old-school Polaris cleaner run for 8 hours a day to keep your pool spotless, you might be disappointed in what a robot pool cleaner—which will generally run for less than 3 hours, and sometimes much less—can do. I’ve never completed a cleaning run with absolutely no debris left behind, but the models reviewed above do a solid job, sucking up 80 to 95 percent of debris, depending on how dirty things are when you started.
More advanced robotic pool cleaners, machines outfitted with treads, do a remarkably good job cleaning up fine debris and algae—much better than hose-type cleaners that need to be pulled out of the pool when you want to swim—and are nearly as good as a human with a brush. This capability alone makes it worth considering a more advanced—and more expensive—unit.
5.
What kind of maintenance do robotic pool cleaners require?
Very little. Robotic pool cleaners need to have their debris baskets cleaned out after each run—you might need to use a brush to clean the filter screen—and you should dry them off, though most are very good at draining within a few minutes of removal from the pool. After a few hours of recharging, the robot should be ready to run again.
Pool robots are electronic devices, so they are prone to breaking down over time—especially given that they will spend ample time underwater. Never leave a robot in the water for longer than its running cycle, and always store it out of direct sunlight, so UV rays don’t break down its plastic components. Naturally, batteries will lose capacity over time, and these are not user-replaceable on any robot I’ve seen.
6.
Are there robotic pool cleaners for above-ground pools?
Virtually every robotic pool cleaner can clean in-ground pools, but many models can also clean above-ground pools, which have different types of surface materials and often lack a smooth floor for the bot to traverse.
Some pool-cleaning robots can handle both types of pools, but don’t assume the one you’re considering can. The manufacturer’s product specifications should indicate which type(s) of pool the robot is designed to clean.
