Pentair Pressure Side Pool Cleaner near the pool.

Pressure side pool cleaners are one of the best options out there for automated pool cleaning. They’re a good balance between cleaning power, maintenance, energy use, and price.

Cleaning the swimming pool is no one’s idea of a fun summer activity, but it’s necessary to keep the water crystal clear and healthy so everyone can enjoy it. Every time someone takes a lap in the pool, and with environmental debris falling into it, harmful oils, chemicals, and germs are left behind. Pressure side cleaners are a smart way to handle all that gunk so you spend more time swimming than cleaning.

How do Pressure Side Cleaners Work

Pressure side pool cleaners attach to the pressure (return) side of a pool’s pump system. Water heading back into the pool pump propels a pressure side cleaner along the bottom of the pool. The cleaner moves in a random pattern along the floor and walls of the pool.

Concept drawing how the pressure side pool cleaner works.

There are two types of pressure side pool cleaners:

  • High pressure (or booster pump cleaners): These require a separate ¾ hp booster pump to power them. They need around 30 PSI to operate best. The booster pump provides a consistent flow to the cleaner. The advantage of this type is that they have a time clock for scheduled cleanings and can automatically stop and start so they don’t run any more than they need to. This saves electricity and wear and tear on the cleaner. The booster pump keeps them from being bogged down by full pool skimmers, pump baskets, and dirty filters.
  • Low pressure: These have no separate booster pump, though they look much the same as their higher-pressure counterparts. They run on just 15 – 17 PSI and need a larger hose of around 1.5” diameter. Initial purchase price and installation is generally cheaper than the booster pump cleaners. Suction power is dependent upon a well-running pool pump and filter system. Full skimmers and dirty filters will bog them down considerably.

How do you hook up a pressure side pool cleaner

Pentair booster pump for the pressure side pool cleaners.

It depends on which type you have and your pool’s plumbing system.

For a booster pump cleaner, you’ll need a Tee fitting installed to the return pipe after the filter. The booster pump sends water through a cleaner pipe midway down the pool wall. If you don’t have a dedicated cleaner pipe, you’ll need to install one first either under the deck and through the pool wall or with an over-the-deck kit.

The booster pump needs either 115V or 230V with a dedicated 15 amp breaker and outdoor timer or time clock. This lets you run it for 2-3 hours a day while the main pool pump is on.

For low-pressure cleaners, they’ll connect to an existing wall return. You may need to test pressure with a testing stick to see if the system can deliver enough power to operate the cleaner. They won’t work in pools with floor or “slit” returns or in pools with pumps less than 1hp.

Pressure side pool cleaner before work.

The best installation for low pressure cleaners happens when water is diverted to the cleaner before it reaches the filter and connected to a dedicated pipe rather than a regular return pipe. This will lessen backpressure on your pool pump and filter tank. You would need to install a 3-way valve between pump and filter, then install another small filter (ex: Jandy Energy Filter) on the cleaner line past the 3-way valve. The open valve diverts water to the cleaner while a pressure gauge on the small filter maintains a constant flow rate.

If you don’t want to do the above method, then you can connect a low pressure cleaner to a regular return line using adapters between ¾” to 1.5” for smooth or threaded pipes. You may need to restrict flow from other return lines just to get enough pressure to the one you’re using for the cleaner. For large pools, if you’re connecting to a return line on the far end of the pool, you may need another length of feed hose, a swivel, and 2 connectors just so the cleaner can reach all areas of the pool.

1Best all-around performance
Exceptionally fast-moving model cleans your pool in no time.

The Hayward Trivac 500 will make short work of your toughest pool cleaning tasks. If a horrendous storm just dumped bucketloads of leaves into your pool, turn it on. It’ll suck up all that unsightly debris without you having to do any manual work whatsoever. With its wide vacuum inlet scoop and triple venturi jet action, it’s guaranteed to pick up more filth and free-floating waste than most other pressure side cleaners on the market.

ProsThe Good

The Hayward Trivac 500 is one of the only pressure side cleaners to skim the surface of your pool. You get more built-in functionality for what you pay for with this feature. Its extra-large debris bag means you’ll only need to empty it about once a week during the swim season. Another great thing about this baby is you can leave it in your pool year-round if you want.

ConsThe Not-So-Good

Some units have a bad habit of getting stuck in corners or the deep ends of pools. There have been reports of the hoses breaking apart when it’s cleaning the pool.

Some say the pump doesn’t have the longevity of some other models.

Customer OpinionWhat Customers Say

Many customers are ecstatic that the Trivac 500 is whisper quiet while still generating lots of pressure. This means it can do a bang-up job without waking everyone up in a ten-mile vicinity.

Other people are impressed with how lightning fast the device cleans every bit of disgusting filth from a pool. Lots of customers loved that the machine has a monkey-like ability to clamber up the sides of pools.

2Best traction
This powerful pressure-side machine makes cleaning easy and effortless.

The Pentair LL505PMG is a pressure-side cleaner that’ll make you deliriously happy. That’s because, with this handy device by your side, your manual pool cleaning days are finally over. This hard-working machine won’t stop until every leaf, twig, and other debris has been removed from every corner of your pool.

Simply attach the LL505PMG to your pool’s booster pump. Then kick back, relax, and experience the exquisite thrill of watching your tireless automaton do all the work!

ProsThe Good

What blew me away when I first laid eyes on this fabulous device was how incredibly quick it was. I said to myself, “How can it clean while going this fast?” On closer inspection, I found that it didn’t sacrifice speed for cleanliness.That’s because the pool it had just worked on was crystal clear without any free-floating garbage to detract from carefully cultivated pool aesthetics.

The speed comes from the two powerful jets in the back.

ConsThe Not-So-Good

The debris bags only last about a year before they start to tear and need replacing. I wish the bags could last a little longer than this. Occasionally, the hose gets all tangled up, which is a bit annoying. For some inexplicable reason, the unit sometimes has a difficult time cleaning the shallow ends of pools.

It also has an unfortunate tendency to get stuck on stairs.

Customer OpinionWhat Customers Say

Many customers love that the device has a front-wheel drive, giving the unit more traction and more control. This capability helps boost the machine’s cleaning power, so you can be assured that every nook, cranny, and crevice of your pool will be covered.

Customers also love its incredible lightweight design, which makes wall climbing a breeze.

3Best at getting into corners
This triple-jet, all-wheel belt-driven cleaner reaches every corner.

Buying an automated pool cleaner is well worth the money if you think of how much it costs in time to clean the pool yourself or pay someone else to do it. If you want a pressure-side cleaner that’ll reach every crook and crevice of your pool, look no further than the Polaris 380.

Its three powerful water jets reach corners and stairs like no other.

ProsThe Good

A generously sized collection bag means you won’t have to empty it as often, saving you time and effort.

The 380 comes with an innovative back-up valve. This means that if it’s stuck in a corner, it’ll back up and keep cleaning. Lesser cleaners spin their wheels until you free them.

With the 380, you’ll spend less time freeing your device from embarrassing predicaments!

ConsThe Not-So-Good

Like all pressure side pool cleaners, the 380 needs a booster pump. One doesn’t come with the unit, so you’ll have to purchase that separately.

On some units, the bags have been known to fall off. Others have an annoying habit of circling too much and consequently tangling up their hoses in knots until they stop working.

Customer OpinionWhat Customers Say

Raving fans of the 380 love how it prolongs the life of their pool filtration system by capturing debris before it reaches the pump basket. Because your filtration system won’t have to work as hard, it’ll last longer.

Others are over the moon that the unit is exceptional at picking up larger debris such as big leaves, rocks, palm seeds, and even golf balls.

Take a Look At These Alternative Models:
  • Polaris Vac-Sweep 3900 Sport Pressure Side Pool Cleaner
    Polaris Vac-Sweep 3900 Sport
    Price: High

    The 3900 Sport has several upgrades over the 380, though it is a good bit more expensive. It has the same three-jet system and backup valve. The 3900 has an additional 40-GPM filtration power through the dual-chambered 5L filter bag whereas the 380 has only a single-chambered bag.

    While the 380 is compatible with the TailSweep PRO (better sweeping power and reduces water spray outside the pool), the 3900 actually comes with this attachment. It has 50% more torque from an all-wheel PosiDrive system with stainless steel chain.

4Best for above ground pools
Powerful water jets sweep debris into a generously sized collection bag.

The Polaris Vac-Sweep 65 is your silent underwater sentinel that’ll work tirelessly to keep dirt, gunk, and debris out of your swimming water. This extraordinary cleaner works on the pressure side of your pump. It distributes clean, filtered water throughout your pool as it moves about.

It’s terrific that it operates off the return jet instead of the skimmer. This way, you don’t have to disable your pool’s skimmer functions.

ProsThe Good

The powerful jets are excellent at circulating the water on the bottom of the pool. This makes sure pool chemicals are evenly distributed.

Whatever fine dust and silt particles the bag doesn’t pick up is pushed back into water circulation. This helps the filter skimmer to remove it.

It’s like having a million tiny swimmers doing their part to stir up dirt so it can be captured!

ConsThe Not-So-Good

The hoses have a nasty habit of tangling up—even after following the manufacturer’s recommendation of laying them in the sun for two days. For a quick fix to this problem, splice pool noodles around the hose in 18-inch sections.

If you read the manual, you’ll likely cut your hoses wrong. Watch a YouTube video instead on how to do this.

Customer OpinionWhat Customers Say

Many customers love that the easily detachable debris bag trails quickly scoop up debris before it has a chance to clog your filter. This will save you loads of cash over time.

Other buyers love that you don’t even have to pull this thing out of the water to empty it. Simply grab it, pull the hanging hose, disconnect the bag, turn the bag upside down, rinse, and reconnect.

How easy is that?

Why buy a pressure side pool cleaner

There are several benefits to owning a pressure side cleaner. One is the time and physical exertion it will save you over having to brush and scrub daily. It will definitely save you money since you don’t have to hire a professional pool cleaner.

With some of them, you can schedule cleaning for specific days and times. Those with large filter bags can capture a ton of big debris and won’t have to be cleaned out constantly. All that debris catching helps prolong the life of your pool pump and keeps it out of your pool skimmer and filter.

What is the best pressure side pool cleaner

There are a lot of choices when it comes to pool cleaners. With pressure side pool cleaners, think about specific features that will work best with your pool setup. The best cleaner is one that fits your budget, thoroughly cleans the type of debris most commonly found in your pool, and doesn’t require constant maintenance. Here are some of the top features you’ll want in a good pressure side cleaner:

  1. Polaris Turbo Turtle at work.
    Cleaning power: Pressure side cleaners remove dirt in a couple different ways. The most powerful ones produce suction like a vacuum and are good for large debris like leaves, acorns, sticks, and rocks. It sucks the debris through an intake throat directly into a filter bag.

    Simpler cleaners just dislodge dirt and “catch” it in the filter bag as it trails behind the cleaner on a sweeper hose. Those will work better for small to medium debris such as sand, silt, and small pebbles.

  2. Booster pumps: Cleaners with the highest suction power will need a separate booster pump. These aren’t cheap, so you’ll need to consider that in the total cost. If you already have a booster pump installed, you’ll need to make sure the cleaner is compatible with it. Not all of them are compatible with every booster pump.

    Low pressure cleaners sometimes don’t require an extra booster pump. Good examples are the Polaris Vac Sweep 165 and the Turbo Turtle. While they won’t cost as much, you must have a strong enough pool pump to power them AND you’ll need to keep your pool filter super clean. Any drop in pressure will bog them down.

    Pressure Side Pool Cleaner cleans the in-ground pool.
  3. Type of pool: Most pressure side pool cleaners are specifically designed for in-ground pools. You’ll find the occasional one made for above-ground pools (ex: Turbo Turtle). The average pressure side cleaner will easily cover an 8-foot deep pool that’s 10’ x 10’.

    Your pool’s surface material is also an important consideration. Concrete and tile pools can handle sturdier cleaners with hard wheels. Vinyl and fiberglass surfaces may get scratched if the wheels are too hard or have rough treads. Be especially careful if you have any pre-existing damage or if you have roots or rocks under the pool floor. For instance, the Pentair Racer can work fine in a vinyl pool as long as the surface is in great condition.

  4. Setup & Maintenance: Automatic cleaners are supposed to save you time, not add to your already full plate. Most cleaners have a downloadable owner’s manual so you can get an idea of how much work it will take to install it. If it looks like the schematics for an interdimensional spaceship, you may want to look for something a little simpler to set up. Otherwise, you’ll have to call a pool expert, and then you’ll be out another few hundred bucks.
  5. Spare parts.

    Maintenance should likewise be as fuss-free as possible, especially if you’re new to using automatic pool cleaners. Filter bags should be easy to remove and clean out. Hardware should be easy to replace when needed. For major repairs, it wouldn’t hurt to research your local pool supply stores to see which brands they can service so you won’t have to spend extra money mailing the cleaner to the manufacturer.

    Spare parts: Certain items will need to be replaced when they wear out. Or you may want different types of parts depending on changing needs in your pool. For instance, leaf filter bags as opposed to all-purpose sand and silt bags.

    Stock up on extra parts when you buy a pool cleaner so you won’t have to wait a long time for parts to come in and won’t have to pause your cleaning schedule. Things to buy – extra hoses, floats, bags, weights, belts, gears, sweeper tails, etc. You’ll find a good list of all these things in most owner’s manuals.

What’s the big deal about booster pumps

One of the necessary evils to owning a high-pressure cleaner is having to purchase a separate booster pump. Your pool’s pump doesn’t produce enough pressure to propel them. But what is it exactly? It’s basically a pool pump without the strainer pot attached. They’re wired and plumbed up in exactly the same way as a regular pool pump. It’s a good idea to place the booster pump at a lower elevation than the return pipe so the pump is always filled with water to prevent overheating. You’ll want to make sure it’s not in any danger from flood water, however, and is also protected from inclement weather and plants/weeds.

Many pool equipment manufacturers also have their own lines of booster pumps. The good thing is that these pumps are usually interchangeable with several types of cleaners. So if you buy one booster pump, it can last through several cleaners from various brands (with proper maintenance, that is)

Common troubleshooting tips

We’ve seen the same types of complaints from customers among all models of pressure side cleaners. These are the issues most likely to crop up if you own one, along with some troubleshooting tips we got from the experts:

  • My pressure side-cleaner is moving slowly.
    1. The first thing you should check is the inline strainer, usually located at the wall fitting. Make sure it’s clean.
    2. Also check the pressure bleed-off valve on the wall fitting. It’s designed to allow excess water pressure to escape, but if opened too much, can make the cleaner sluggish
    3. Pentair Racer at work.
      Check the hose between the wall and cleaner. Carefully inspect to see if there are any splits or holes. Replace any damaged hoses. A little leakage at the swivel joints is normal.
    4. Slightly lift the cleaner out of the pool. There should be a solid, steady stream of water that sprays out 10 – 20 feet from the back of the unit. Remove the filter bag. The water should shoot up nearly 20 feet from the venturi (top). If the stream is weak in either area, check the sweep tail adjustment screw. If it’s loose, tighten it, and if missing, replace it. Inspect the tail for holes or a missing tip.
    5. Inspect the wheels and belt-drive or gear system. If there are any sticks or sand jamming them up, clean it out. Adjust the wheels if they are too tight or loose. Replace any worn belts or drive shafts. If treaded tires have become worn down, replace them so they have better traction.
  • My pressure side cleaner isn’t reaching the entire pool.
    1. Check the thrust jet. The default is set at 11:00. Try 1:00 to move the track in the opposite direction.
    2. Is the hose a proper length? Cleaners will need plenty of hose to reach the far corners and deep end. Too much hose can get tangled or inhibit the cleaning pattern.
    3. Most pressure side cleaners won’t do much for steps, stairs, and loveseats. You’ll need to brush and net them manually every now and then.
    4. Stuck in the deep end? Adjust the hose floats. Add 1-2 more floats if necessary. Check for pressure loss at the wall fitting, hose, or inside the unit.
  • My pressure side cleaner gets stuck in one area.
    Polaris Vac-Sweep 165 stuck in a tight corner.
    1. If your cleaner is getting stuck behind the ladder, there are ladder guards available like this one from Polaris that block the cleaner from getting stuck.
    2. If stuck on the main drain, try a drain cover to smooth the transition from drain to floor so the wheels can glide right over.
    3. Watch to see if it will back itself out of a jam. A hydrotimer in the back-up valve pushes the cleaner off the floor every 3 minutes or so and often helps to get it going again.
  • My pressure side cleaner back-up valve isn’t working.
    1. If your cleaner is getting stuck and doesn’t get itself out, the back-up valve may be broken or clogged. Inspect for damage or flush the valve out with water.
    2. Check the hose floats on either side of the back-up valve. If they are letting the valve drag across the floor, the valve casing can get damaged.
  • My pressure side cleaner hose is tangling.
    Hose is about to tangle during pool cleaning.
    1. Make sure you don’t have TOO much hose. Follow the owner’s manual to ensure you have the proper length to fit your pool.
    2. There may be too much pressure (power) propelling your cleaner, which can cause it to move around in circles, thereby tangling itself. Adjust pressure where needed.
    3. Make sure all hose swivel joints are moving freely.
    4. Are all hose floats actually floating? Adjust them until they are. If they still sink, they may have taken on water and need to be replaced.
    5. Stiff hoses can tangle more easily. Remove from the pool, stretch it out in the sun and let it sit for a day. If it still wants to coil and feels brittle, it’s time to replace either the entire hose or affected sections with a softer, more flexible hose.

Final thoughts

Buying an automatic pool cleaner of any type is one of the smartest investments you can make for your pool. Try to purchase the best one that your budget will allow for, as you usually get what you pay for with pool cleaners.

Our top recommendations are the Polaris Vac Sweep 380 or the Pentair Racer. Both are exceptional at removing high volumes of debris and get it done quickly, saving energy and giving you more time to enjoy the pool.

You sold me on the Hayward TVP500C TriVac 500 Pressure Cleaner. However, I do have one question. Will the 30” of hose included with the unit be enough to clean my 30” pool’s entire length without moving it to a different jet?

Hi, Johnson. Thanks for reaching out! You should have no trouble covering the entire length of your pool without having to switch it to a different jet. I hope this helps!

My Polaris Vac-Sweep 65 is forever getting stuck in the same spot. I’m continually jumping in to rescue the damn thing, and I’m getting sick of it. How do I rectify this annoying problem?

Kevin (Cleanup.Expert Team)
April 7, 2021 at 7:52 am

Hello, Steve! The first thing you’ll want to do is check underneath the unit to see if any of the water exit holes are clogged.
If they are, unclog them and see if this fixes things.
It could also be a faulty backup valve. Watch your Polaris move around the pool for a few minutes. If it doesn’t stop and reverse itself when it needs repositioning, you’ll probably have to replace the valve.

The pool cleaner I used to have for my 20,000 gallon inground was constantly tipping over, which was so annoying. I’m thinking of buying the Pentair LL505PMG Kreepy Krauly because with four wheels, it’s supposed to be exceptionally stable. What have you heard?

Kevin (Cleanup.Expert Team)
March 10, 2021 at 5:47 pm

Hi, Louis! There are a surprising number of pool cleaners out there that have a nasty habit of tipping over. However, I don’t think you’ll have that problem with the Pentair LL505PMG.

It’s one of the most stable models I know, and friends of mine who had one were quite pleased with it.

Take care, and have a wonderful day!

Should I run the pool pump at night or during the day?

Kevin (Cleanup.Expert Team)
February 14, 2020 at 9:27 am

There are pros and cons to each. For daytime, the circulation is good for maintaining the chlorine levels during peak sun exposure. For normal operation in really sunny, warm climates, it’s probably best to run it during the day. But at nighttime, it’s cheaper to run it for your electric bill during off-peak hours. Nighttime is also good if you’re doing a chemical treatment and need a really high chlorine level – that will prevent any sun burnoff. You could also try splitting it – running it 4 hours during peak sun time and then 4 hours overnight.
