Vac-Sweep 280 – Best Affordable Pressure Side Pool Cleaner
If you are on a budget and you want a high-performance pressure side pool cleaner, get this model. It boasts much of the features that the more expensive model 380 has and is equally effective and durable.
But remember, this is the base model in the Polaris pressure pool cleaners line so don’t expect it to have the latest features. But still, it packs quite some good features that will make sure your in-ground pool water is clean always. I bought this model in 2015 and it used to do a great job on my in-ground pool.
But remember, this cleaner requires a booster pump that you buy separately so when budgeting, include around $250 for the pump. After 8 months of excellent service, I traded it and got the bigger Polaris 380 and there are a few things the Polaris 280 would make you want it more.
First, it is cheaper and the maintenance requirements are minimal. It was also able to capture much larger debris and actually, more than what the 380 holds. But then, the 380 offered so much more and the fact that my newer pool was almost two and a half times larger than the previous one, obviously I needed something bigger.
You see, this model is ideal for mid-sized pools because of several factors that we’ll later discuss in this review. Before I forget, there is one thing I hated – the wheels often got jammed so you have to pull it out and free it.
Polaris Vac-Sweep 380 – Bigger and Better Performance
I moved to a new neighborhood in some property that had a larger pool and the environment too suggested that I had to get a more powerful and faster pool cleaner and that’s why I went for the Polaris 380.
But oh my, it costs a fortune.
But then, it offered better and bigger performance and notably, it cleaned faster!
But then, here’s a word of caution – it has quite a number of extra parts and thus will require intensive maintenance. But anyway, that’s something to expect now that it offers better performance than the junior.
Still, with this model, you will require a booster pump so remember that when doing budgeting.
But on a positive side, this pool cleaner has better movement and maneuverability and would cover large pools quite faster considering the navigation mechanism is revised. But then, is it worth the few hundred more dollars. Personally, I wouldn’t say yes fully – it’s very hard to call but then that will be your verdict.
Just to point out, you will also come across model 360 and it would be important to know the difference between the two.
This is another pool cleaner that’s very similar to the 280 and 380, but the major difference being the feeder pump. While models 280 and 380 will require a booster pump to work, Polaris 360 will work with your existing pool pump so it is a cheaper option if you don’t want to invest in a separate pump. But then, before buying this cleaner, make sure it is compatible with your pool pump.
Polaris 3900 Sport – The Ultimate Pressure Side Cleaner
What’s about slopes? If you’ve ever tried the 280 or 380, you understand that it is mission impossible. The two have been designed to work on flat floors and when the pool floor begins sloping, they become useless. But the 3900 Sport has been designed to work on both flat floors as well as gradual slopes. This is courtesy of a revised drive system and also, newly designed off-road wheels.
Some of the new improvements include a larger bag and a more stable wheel system. But the best highlight is TailSweep Pro, a new extension feature that reduces splashing and boosts cleaning.
The good news is that while the previous two models are just compatible with TailSweep Pro, the 3900 comes with one included. But if you bought the earlier version of the Polaris 3900, it is regrettable that you lack several new tweaks that the latest versions come with. While the old version had problems with the drive chain falling off the gears, the latest version has a chain guard. Another thing, the head float is now removable so you don’t have to replace the entire top body when the head float dies.
But then, there are a few problems I’ve noticed with the 3900 Sport. One, when the bag is full, the weight makes it want to topple over especially on the slopping areas. Also, emptying the zipper bag is quite hectic because it binds too easily.
But all said and done, it is still a great pool cleaner and actually, the best in the category of side pressure pool cleaners.
TailSweep Pro for Automatic Pool Cleaners
If your pool is just next to the window, you know how much it’s stressing when pool water splashes on them.
So, Zodiac came up with a simple solution – TailSweep Pro. This is an advanced sweep hose enhancement that boosts water propulsion to blow out stuck debris form those hard to reach places. Besides this, it prevents pool water from splashing outside of the pool. But how exactly does it work?
TailSweep Pro is compatible with the 280, 360, 380 and also 3900 Sport. But then, not all models come with the equipment included so it raises the question, is a worthy purchase?
Personally, I don’t find it a necessary investment if you have a spacious pool and wider side steps. I used it first with the 3900 Sport and trust me, it works magic. If your pool is near the window or you just don’t want pool water to splash around, get a TailSweep Pro or just buy the Zodiac 3900 Sport (it comes with one included).
I know you are wondering what a booster pump does and a burning question lingering in your mind would be, must you have a booster pump?
I won’t tell you that it is a must that you have a booster pump but then, it is a requirement for optimum operation. Yes, a Polaris cleaner will still do the job minus a booster pump but then, it won’t put up 20% of the requirement for the task to be complete. That said, without a booster pump, the efficiency is around 20%.
But if you want a cleaner that doesn’t require a booster pump, then get model 360 – it will use the existing pool pump installation. But now that you have the Polaris 280, 380 or the revolutionary 3900 Sports, you will be required to buy a booster pump.back to menu ↑
Black Max Models
If you have a dark bottomed pool, Polaris offers equally dark color options known as Black Max models.
Though the black color might make you think that they could be more rugged, it’s only the color that’s different – every other thing is still intact.back to menu ↑
Face to Face models comparison
Now that we know a few things about side pressure cleaners, it’s time we try to compare them and see which one is the best in which area.
That said, let’s see how the battle is squared out.
Type and cleaning priority
The first thing you would want to consider when shopping for a pool cleaner is, what type of pool cleaner do you want? And then, what is the cleaning priority?
That said, let’s look at how the three cleaners battle it out here.
If you did your homework, you understand that there are different types of pool cleaners, each offering different features.
For the record, all models in the review are all pressure side cleaners.
Now, what about cleaning priority? Different pressure side pool cleaner will clean different places.
When shopping, make sure that you buy a pool cleaner that cleans all surfaces regardless. Besides, get one that will be comfortable on the pool floor whether it is flat or gradually sloping.
One thing I like about this brand is the versatility. I used to clean the floor and walls with the 280 and 380 and the results were astounding. Also worth mentioning, the 380 can also clean steps but then the performance is not up to the mark.
But what if you have a gradually sloping pool floor? This is where the 3900 Sport comes in – it can handle floors, walls and even gradual slopes courtesy of the wide wheels – that’s a story for another day. Having said that, you will want to get the more expensive Polaris 3900 but obviously for a reason – versatility!
Waterline is the most complicated pool area to reach. Only the best and, consequently, most expensive cleaners can process this zone. However, not all pool owners really need such a function. So, though the 3900 is the best, in my opinion, customers on a budget can choose more affordable options and clean waterline manually with special brushes.
Design and Aesthetics
I know the looks of a pool cleaner are not important in a cleaner but there are some people who are very choosy.
The Polaris 280 and 380 boasts a similar design and aesthetics – only size is the major noticeable difference but on a closer look too, you will realize the 280 has a smaller wheel between the two main large wheels.
But generally, they look similar. The same applies to the 360 – wholly resembles the 380 save for a few tweaks because of the pump requirements in the 380. But when it comes to the 3900 Sport, a whole new design is brought on board – bigger, bulkier but more sleek and stylish.
I am sure this is what you have been waiting for all this long as cleaning is the primary role of Polaris.
But, is their cleaning performance the same or there is one that is better? Actually, from the varied price ranges, it would be insane if these cleaner offered the same cleaning performance. That said, we obviously expect several variations in features that consequently bring about the varying cleaning performance.
So, just how do these pool cleaner rank when it comes to keeping your pool clean?
But then, it would be quite a task to discuss cleaning performance in general as there are several aspects that come into play for the pool cleaner to work. That said, we will look at a series of features and compare them to see how they vary in each model and ultimately, how they make a difference in the cleaning performance.
Bag capacity– I know for many people, the bag capacity is something you wouldn’t want to gamble with.
The 3900 Sport is the ultimate winner here with a large 5 liters bag. The 280 also has an impressive size – 3 liters to be precise. Unfortunately for the 380, it has a much lesser bag so if your pool has a lot of debris, it won’t be a great purchase.
But notably is the 3900 Sport’s Superbag with a fully zippered access. Besides the large capacity, it has a new Twist Release connection for stress-free detachment when full and easy attachment thereafter.
Polaris offers a nice price for its zip-locked bags. That’s why I’d recommend getting such a bag regardless of the cleaner model you have, as you’ll save lots of time on its emptying further.
Venturi jets – As you all know, this robot cleaner moves around using the venture effect principle. Basically, the incoming water is converted into a powerful suction current via the jets.
The Polaris 280 has only two venture jets and works just fine in an average sized pool. However, the 360, 380 and 3900 Sport come with three venture jets so definitely, they have more power than the 280. But then you will realize that even though the 380 and 3900 have three jets.
Hose – The hose length would be a really important consideration but not with these cleaners.
I’ve only replaced once and it was due to my kids’ carelessness. But the build, material, and durability are unquestionable.
Tail Sweep Pro – This is a simple but very efficient add-on that helps to prevent water from splashing out of the pool.
Backup valve – Though these cleaners are automatic, and in fact robotic to some level, they are not as intelligent as robotic floor cleaners like the Roombas. You see, Roombas have a navigation system that will guide them all through. But these cleaners lack such a system so getting stuck is a major concern especially if you have a large pool. But the good thing is that the backup valve will pull back the cleaner randomly just in case it is stuck. Though not a really clever solution, it does the job – preventing the pool vac from getting stuck.
Drive system – Like earlier mentioned, among the greatest strengths of the 3900 Sport is the drive system – more advanced and efficient. It features a PosiDrive system driven by a stainless steel chain and you will definitely notice the enhanced power compared to the 380. Though the torque is not 50% more as the manufacturer suggests, this is a pool cleaner you’d want to have if you have a larger pool. It cut the cleaning time by almost 30%.
On the other hand, the 360 and 380 have a belt driven system while the 280 is gear-driven. Between the 280 and the 380, I didn’t notice much difference though the belt driven system is best because it requires less maintenance compared to a gear system. That said, the battle remains between the belt-driven system and chain drove system.
This is very hard to call as both systems have advantages and disadvantages which in fact, are very relative.
Tires – Though they are not directly related to cleaning, they greatly influence where the cleaner will reach. So far, Zodiac has two types of wheels in these side pressure cleaners; Classic and WideTrax. The 280, 360, and 380 have Classic tires which work just fine but then, stability is compromised, especially when the bag is full. Also, they can’t be used on gradual slopes because of less traction.
Cost and value for money
Before paying for any pool cleaner, first ask yourself, are you getting value for money? Don’t just buy a pool cleaner because you can afford it or just because it is cheap. Do a simple survey, and if possible make a checklist of the features to expect at every price range. This way, you will have a rough idea of what you should expect in a cleaner that is within your budget.
When it comes to our Polaris 280 vs 380 vs 3900 comparison review, I wouldn’t say that there is any cheap cleaner. But then, this is a top brand so there’s no way you should expect them to be cheap. But how do they fair on when it comes to value for money?
280 is a middle-class option for the price, I wouldn’t say it is cheap or expensive. But when you consider the features, I see value for money. Though it is smaller, it packs the most important features that the 380 has.
But then, the bigger model, 380 is quite expensive and cuts downs some key features. For example, I don’t expect it to have a smaller bag. Here, I would rather top up extra $$$ and get 3900 Sport. This one looks like a seriously upgraded model and brings on board a range of new features unlike Polaris 380.
That said, I agree that the 3900 Sport is expensive but then, worth every penny. It will clean floors, walls and gradual slopes while the cheaper Polaris 380 will only do floors and walls.
What is the best Polaris Side Pressure Cleaner?
Polaris 3900 Sport is a hybrid pool cleaner that tries to combine the fancy features of the 280, 380 and 480. And honestly speaking, it has successfully managed to dominate the market, especially with the new upgrades it has undergone over the years. Though it is quite expensive, it is real value for money.
Which Polaris cleaner do I have?
Many are times pool owners buy the wrong replacement parts. Though there are times retailers send the wrong product, a lot of times it’s because you order for the wrong replacement parts. My wife once ordered replacement parts for the 280 when we had already upgraded to the 380 – I assumed she would figure it out.
If you don’t know the model of the pool cleaner you have, the best way will be to check the serial number found on the back of the cleaner. The first letter of the serial number tells you the model – the 280 starts with C, while K is the 380 and L will be the 360. Definitely, it wouldn’t be a problem to spot the 3900. You won’t miss the extra-large wheels and bulky design. You should also be able to see the difference between the 280 and the 380 from the wheels: the first has three wheels and the second has two.
Polaris Side Pressure Pump Troubleshooting Guide
Many are times your pool cleaner will malfunction for no good reason. At times it’s worse and the fear of having to buy another one starts to creep in. But in most of such occasions, it might just be a small problem that you can figure out yourself. Having come across dozens and dozens of such situations, I will share with you the common problems your Polaris might encounter and the best troubleshooting tip.
So, without wasting more time, here is the side pressure cleaners troubleshooting guide.
1. My cleaner is very slow
I’m sure this is a problem you will encounter and through experience, it can be caused by a number of factors. So, whenever the Polaris is sluggish, and looks moody, here are the areas to check.
The first culprit would be the inline strainer, usually installed along the wall fitting – it could be dirty and that’s something that can make the cleaner slower than usual. If the strainer is clean, move to the hose and the first thing I want to say here is, while it may sound clever to use a longer hose, it will drastically cut down power. That said, you will want to use the recommended 31’ hose and if this is what you are using, it will be time to look for answers by examining pressure.
The first thing to do here, slowly and carefully examine the entire hose looking for possible leakages. You all know leakages will lower down the water pressure, and consequently, the cleaners speed. Then, move to the cleaner unit itself to ascertain if there is an internal pressure loss. Gently and slightly lift the cleaner and examine the flow rate from the back via the thrust jets. The cleaner should have a solid and steady stream and if it shoots anything between 10ft. and 20ft., it should be fine.
So what next? Remove the debris bag and check the height of the venture stream jet – it should hit at least 20ft. If your cleaner doesn’t satisfy any of the two tests, then know there is water loss internally. In most occasions, the problem with water loss is associated with the sweep tail – any holes or missing tips allowed too much water to escape. There was also a rare incident where the sweep tail adjustment screw worked out and got lost – I replaced it and the speed was back to normal. Also, note that there are wall fittings with pressure bleed-off valves to get rid of excess water – opening this valve too much may slow the cleaner.
If the pressure is fine- from the hose to the unit itself, then you should shift your focus to the wheels and drive system.
Do a spot check on the wheels and remove any debris that may be hindering freewheel motion. Also, make sure they are not jammed internally with small debris like sand and twigs. Try to push them with your hand and feel the ease.
Another culprit is the drive system and in most cases here, the parts may be worn out so definitely, performance will dip. Check the drive belt and drive shaft and if need be replace them. There are also some models like the Polaris 180 and 280 that are known to have weak wheel grooves and teeth that crack or break – this requires replacement.
2. Hose tangling
This is a rare but very common problem that cleaners may experience.
Like earlier mentioned, too much hose could be a problem and besides lowering flow rate, it leads to tangling. With a long hose, especially replacements, the different movement directions will loop it more and with the cold temperature and brittleness, it develops a memory of the coil. That said, you will want to remove it from the water and stretch it out in the sun. Another problem would be the swivels – check them out and make sure they are intact and also, make sure the floaters are still floating.
3. Backup valve malfunctioned
I know I said that it’s hard for a Polaris cleaner to get stuck but the truth of the matter is that it is not invincible. The first time I found my 280 stuck I was just expecting the worst but then, the problem was with the backup valve.
A common fix here would be to unclog the valves – sand and other small debris will block the valves and so, the cleaner won’t be able to pull out when it gets stuck.
I experienced the same problem with my Polaris 380 and this time round, everything was fine as far as blockage is concerned. I noticed a small hole on the bottom of the backup valve and upon a short investigation, I found out that it had dragged itself on the floor way too long. Apparently, the hose floats were dysfunctional so it couldn’t stay afloat.
4. Cleaner got stuck in one place
There could be a lot of reasons why the cleaner gets stuck in one place.
Remember, this might be different from backup valve malfunctioning in the sense that this time round, there are specific spots where the cleaner gets stuck. One of the areas is the ladder. Yes, you want clean water and safety too for your family but then, with Polaris, you have to sacrifice a few dollars and get a ladder guard. In some tight corners also, you will have to consider brushing them manually to avoid a lot of trouble.
5. The pool vac tumbles over
Save for the 3900 Sport, this is a common problem with the 280, 360 and 380.
There are two reasons that could lead to this – a full bag and defective floaters.
That said, you don’t want your cleaner to still be moving around with the bag full. Another thing, check the rear floater and if this is the problem, more often you will find it with water. If this is the case, then know it’s time to get a rear floater replacement.
