A suction pool cleaner makes pool maintenance far easier by automatically vacuuming debris from the floor and walls of a swimming pool, and to find out which models are actually worth buying, we tested six popular options in a Florida inground pool. These cleaners connect directly to the pool’s suction system and move around on their own, collecting dirt, leaves, algae, and other debris while reducing the need for manual vacuuming and brushing. During testing, we evaluated setup, wall-climbing ability, scrubbing performance, movement speed, and overall ease of use.

While most swimming pool cleaners perform the same basic function, the difference in real-world performance can be surprisingly noticeable. Some models struggled to move properly or required extra adjustments before they could even start cleaning, while others climbed walls effortlessly and aggressively scrubbed the pool surface as they moved. Our favorite by far was the Zodiac MX6 thanks to its fast movement, strong wall-climbing ability, and treaded-wheel design that helped it scrub far more effectively than the competition.

Ahead, we’ll break down our favorite tested models, highlight the features that matter most when shopping, and explain what separates an average cleaner from one of the best suction pool cleaners on the market.

Best Suction Pool Cleaners at a Glance

Our Top Picks

The list below includes pool cleaners designed to suit a variety of pool types to help easily maintain your pool, including above-ground and small inground pools, as well as large pools. 

Our Ratings

The Zodiac MX6 stood out as the best suction pool cleaner we tested, thanks to its fast movement, strong wall-climbing ability, and impressive scrubbing performance. As soon as it was connected to the suction hose, the MX6 immediately began moving quickly across the floor and walls of our Florida inground pool without requiring any adjustments or fine-tuning.

Unlike many suction cleaners that simply glide across the pool bottom, the MX6 uses treaded rubber tracks and a large rubber scrubbing disc underneath the cleaner to actively agitate dirt and algae as it moves. Combined with its aggressive cleaning pattern, it consistently covered more of the pool and scrubbed more effectively than the other models we tested. It also handled wall climbing extremely well, maintaining traction even during steeper climbs.

Setup was simple thanks to the quick-connect hoses, and overall reliability was excellent during testing. Occasionally, the cleaner would flip onto its back around awkward pool transitions, though it always corrected itself and resumed cleaning on its own shortly afterward.

What our tester says: “This was easily the best overall cleaner I tested. It moved faster, scrubbed harder, and climbed walls better than anything else in the pool.”—Paul Rankin, Product Reviews tester and writer

Hayward’s Wanda the Whale combines reliable cleaning performance with a fun design that stands out from the sea of generic pool cleaners. During testing, we liked how the whale-shaped body and flapping tail gave it a playful appearance as it moved across the pool floor, making it an especially fun option for families with kids.

Despite the whimsical look, Wanda handled routine cleaning surprisingly well. It moved smoothly along the bottom of the pool, picking up dirt and smaller debris without issue. The bumper ring helped it avoid obstacles and navigate corners more gently than some of the other models we tested. However, it struggled to climb the walls of our pool and mostly stayed confined to floor cleaning during testing.

The included 32-foot sectional hose provides plenty of reach for most above-ground pools, and long-term testing from our team has shown it to be a dependable weekly cleaner. Just note that larger leaves can clog the hose, and the decorative tail occasionally pops off during use.

What our tester says: “This is the go-to pool cleaner if you have kids you want to entertain while doing it. Not only does it look cute, but it actually does a great job at cleaning, too.”—Paul Rankin, Product Reviews tester and writer.

Our Ratings

ThePoolCleaner from Hayward impressed us with its simple setup and strong wall-climbing ability. Out of all the models we tested, this cleaner handled climbing the walls of our pool the most consistently, thanks in large part to its large ribbed rubber wheels that provided excellent traction across the pool floor and walls.

Setup was super easy compared to some other suction cleaners we tested. We connected it to the suction hose, dropped it into the pool, and it immediately started cleaning without requiring extra adjustments or tuning. The ribbed wheels also provide a mild scrubbing effect as the cleaner moves, helping loosen dirt and algae while vacuuming debris into the filtration system.

While the wheels do scrub the pool surface, they’re fairly narrow, so the cleaning path isn’t quite as aggressive as some disc-style cleaners like the Zodiac MX6. During testing, we also noticed the cleaner struggled slightly with curved pool corners, occasionally preventing it from fully transitioning onto the wall.

Still, for dependable climbing performance and easy day-to-day operation, this Hayward cleaner was one of the strongest performers we tested.

Our Ratings

The Zodiac G3 was one of the fastest-moving suction cleaners we tested, making it especially effective for quick routine cleanups. Right out of the box, it worked immediately without requiring any extra adjustments, which wasn’t the case with some competing disc-style cleaners we tested.

What stood out most during testing was how quickly the G3 moved across the pool floor and walls. That fast movement helped the cleaner scrub more aggressively than slower-moving models, allowing it to pick up dirt and smaller debris efficiently. Its large disc design also helped it maintain solid suction while climbing walls in our inground pool.

We also liked how compact and maneuverable the cleaner felt overall. It navigated corners well and rarely got stuck during testing. However, while the performance impressed us, the build quality didn’t feel quite as premium as some higher-end competitors. The visible plastic seams look somewhat flimsy, and over time, we’d question how well it would hold up to heavy long-term use.

Still, for quick, effective cleaning with almost no setup frustration, the Zodiac G3 is a strong value option.

Our Ratings

Pentair’s Kreepy Krauly Kruiser was the best-built disc-style suction cleaner we tested. Right out of the box, it started cleaning immediately and delivered excellent overall performance across both the floor and walls of our inground pool.

Like the Zodiac G3, the Kreepy Krauly moved quickly and did a great job at climbing the walls, but its construction felt noticeably more durable during testing. The seams are covered with rubber flaps that not only improve longevity but also act as bumpers when the cleaner taps against pool walls and edges. It felt more refined and sturdy than many of the competing suction cleaners we tested.

The cleaner also handled pool navigation well, moving smoothly around curves and obstacles without constantly getting stuck. Its directional movement system helped it cover the pool evenly, while the suction and scrubbing action picked up dirt and smaller debris efficiently.

While it didn’t quite scrub as aggressively as our top-pick, the Kreepy Krauly delivered a great balance of performance, durability, and ease of use that makes it especially appealing for inground pool owners looking for a dependable long-term cleaner.

How We Tested the Best Suction Pool Cleaners

We researched more than 20 suction pool cleaners before narrowing the field down to six popular models for hands-on testing in a Florida inground pool. During testing, we evaluated how easy each cleaner was to set up, how well it navigated the pool floor and walls, its overall cleaning speed, scrubbing ability, suction performance, and whether it became stuck around curved corners, steps, or transitions. We also compared build quality, hose design, movement systems, and overall ease of day-to-day use.

Because wall cleaning is one of the biggest advantages of a good suction cleaner, we paid especially close attention to wall-climbing performance and traction across different pool surfaces. We also looked at how aggressively each cleaner scrubbed algae and debris while moving, since some models only vacuum while others actively scrub the pool surface. Finally, we compared value by including a mix of affordable above-ground cleaners and higher-end inground models to find the best suction pool cleaners for a variety of pool owners and budgets.

What to Consider When Choosing a Suction Pool Cleaner

When shopping for the best suction pool cleaner, it’s crucial to consider its compatibility with the pool pump as well as hose length and the type of pool surfaces it can clean. Below, learn more about these and other attributes of suction pool cleaners. 

Pool Type and Surface

Before buying a suction pool cleaner, make sure it’s designed for your specific pool type and surface. Some models are made just for above-ground pools, while others are better for larger inground pools with deep ends, stairs, and wall-climbing requirements.

• Above-ground pool cleaners are usually lighter, simpler, and focused mainly on cleaning the pool floor.
• Inground pool cleaners typically offer stronger suction, better traction, and improved wall-climbing performance for more complex pool layouts.

Pool surface compatibility is just as important. Common pool finishes include concrete, gunite, vinyl, fiberglass, tile, and pebble. A cleaner that isn’t compatible with the surface may struggle to maintain suction, fail to climb walls properly, or potentially cause wear to delicate materials like vinyl liners.

Features like rubber tracks, wheels, and scrubbing discs also perform differently depending on the pool surface. Before buying, check the manufacturer’s recommendations to ensure the cleaner is compatible with both your pool type and finish.

Pool Size and Shape

Pool size and shape both play a major role in how effectively a suction pool cleaner performs. Smaller cleaners are often a better fit for compact pools because they can move more nimbly through tight spaces and around obstacles. Larger pools, meanwhile, benefit from cleaners that move quickly, cover ground efficiently, and include long hoses capable of reaching far corners and deep ends.

Pool shape is equally important. During testing, we found that some cleaners struggled with curved pool corners, awkward transitions, tanning ledges, or steep wall angles. Certain models occasionally became stuck or failed to fully climb walls depending on the pool’s layout, while others navigated more complex shapes with ease. If your pool has unusual curves, built-in steps, or a freeform design, it’s worth prioritizing a cleaner with strong traction, reliable wall-climbing ability, and a proven navigation system.

Pump Compatibility

Suction pool cleaners work by using the power of the pool pump to suck up debris and propel themselves across the pool bottom and up the pool walls. Most manufacturers list the minimum flow rate required from the pump for the cleaner to operate properly. Suction pool cleaners typically require a flow rate of 1,600 GPH to 2,200 GPH. 

Hose Length

Suction pool cleaners may not have a power cord, but they are attached to a 1.5-inch hose that sucks up debris and transports it to the pool filter and pump skimmer basket. The range of the suction pool cleaner is limited by the length of the hose. Suction pool cleaners typically come with 7 to 10 lengths of hose that can be connected to extend the hose length up to 30 to 40 feet.

To calculate the required hose length, measure from the skimmer to the farthest corner of the pool, then add the depth of the water. If the farthest point from the skimmer is 25 feet away and the swimming pool has a depth of 5 feet, you’ll need at least a 30-foot hose to clean the pool. 

Debris Type and Amount

Pool cleaners also vary in the type and size of debris they can handle. Most pool cleaners are capable of sucking up sediment, small particles, and leaves. 

While some pool cleaners may struggle to suck up larger debris, others have designs that allow them to remove larger leaves without clogging. There are models that also come with integrated scrubbing brushes to help remove residue. 

Filtration System

Unlike robotic pool cleaners that collect debris in their own onboard filter baskets, suction pool cleaners rely entirely on the pool’s existing pump and filtration system. As the cleaner moves through the pool, dirt, sand, algae, and smaller debris are pulled through the hose and sent directly to the skimmer basket and pool filter. Because of this, a suction cleaner’s performance is closely tied to the strength and condition of the pool’s filtration system.

Pools with weaker pumps or undersized filtration systems may struggle to provide enough suction for some cleaners to move properly or climb walls effectively. During testing, we also found that larger debris, such as leaves or twigs, could occasionally clog certain models with smaller intake openings. Before buying a suction pool cleaner, it’s worth checking the manufacturer’s recommended pump flow rate and making sure your filtration system is properly maintained for the best cleaning performance.

Tips for Suction Pool Cleaner Use and Maintenance

In order for that new pool cleaner to do its job, it’s crucial for it to be maintained properly. Make sure to remove it after each cleaning cycle. The chemicals used to treat pools can damage the pool cleaner if it’s exposed to them for too long. 

Make sure to clean the pool cleaner after each use. Clean any dirt that accumulates inside, and check to make sure that any wheels or moving parts aren’t clogged with debris. It’s also a good idea to rinse the cleaner with fresh water to prevent pool chemicals from damaging it. Any algae growth on the walls will prevent a pool cleaner from being able to climb. 

To get the most out of a pool cleaner, control algae growth by making sure the pool chemistry has the proper pH and chlorine levels.

• Remove the pool cleaner from the pool after each use.
• Regularly remove any debris from the pool cleaner.
• Control algae growth in the pool to ensure the pool cleaner can climb.

FAQs

If you’re wondering how suction pool cleaners work or if they require electricity, then read on for more information about this type of pool cleaner. 

Q. How do suction pool cleaners work?

A suction pool cleaner works by connecting directly to your pool’s skimmer via a 1.5-inch hose. As the pool cleaner moves around the pool, it sucks up dirt and debris, sending it to the pool filter and pump basket. 

Q. How much electricity do suction cleaners use?

Since pool cleaners are powered entirely by the suction force of the pool pump, they do not use any electricity. 

Q. Why do people like suction pool cleaners?

Suction pool cleaners are the most affordable type of cleaner. They also have fewer moving parts than other types of pool cleaners, making them easier to maintain, and they don’t require a booster pump.  

Q. How often should I use my suction pool cleaner?

Use the suction pool cleaner about twice a week during the in-season when the cover is off the pool. During the offseason, remove the cover and run the cleaner about once a month. 

Q. How long will a suction pool cleaner last?

A good suction pool cleaner will last from 5 to 7 years when properly maintained. 

Q. What is the difference between a suction pool cleaner and a pressure pool cleaner?

A suction pool cleaner attaches directly to the pool skimmer and removes debris by sucking it through a hose to the pool filter and pump basket. 
A pressure pool cleaner attaches to the return jet of your pool’s pump and filtration system. It works by sucking up debris and depositing it into a bag attached to the cleaner.

Q. Are suction pool cleaners easy to store?

Yes, most are small units that come with long hoses. As long as you have somewhere to store the hose, the cleaning head is normally small enough to store away easily.

Q. How much can I expect to spend on a suction pool cleaner?

A half-decent suction pool cleaner, like Wanda the Whale, is under $200. More premium models can cost up to $500 or more. This is still more budget-friendly than a robot pool cleaner, though.
