Suction or Pressure Side Pool Cleaner?

Suction or Pressure Side Pool Cleaner

To answer that question it would be best to give a brief explanation of the difference between a pressure side pool cleaner and a suction side cleaner. A pressure cleaner uses the return water from a separate dedicated booster pump to propel the cleaner around the pool. A pressure cleaner has a bag on top of the cleaner and the pool’s debris is collected in the bag. A suction cleaner uses your main filtration pump to suck up debris which is then returned to your pump basket. To determine which cleaner is best for your pool let’s dig a little deeper.

Pressure Side Cleaners

polaris2803Though I believe pressure side cleaners are the better of the two options not all pool’s are equipped with a booster pump or have room to add one. Most pressure cleaners require a dedicated booster pump be installed, so if your system was built with the plumbing for a pressure side cleaner then a pressure cleaner would be right for you. If your pool was not plumbed for a pressure cleaner then there is a special cleaner called the Polaris 360 which works off of the return water of your main pool pump. Unlike the name implies a pressure cleaner does not power blast your pool surface, the cleaner actually uses your pools return water to create a suction vortex to pull debris from the pool into a bag attached on top of the cleaner. As mentioned before the pressure side cleaner requires a dedicated booster pump to push water through the cleaner to create this jet stream. The pressure side cleaner is ideal for heavy debris because of its wide throat design. The large throat design allows for large clump of leaves, large acorns and twigs to be caught into the cleaner bag without fear of clogging.

Suction Cleaners

Suction cleaners are susceptible to issues of low flow, so if your filter is ¾ horsepower or lower I would suggest contacting the manufacturer to determine that your system meets the required cleaner flow rate.

A suction side cleaner is essentially a vacuum cleaner that runs off the suction power of your main pool pump. The cleaner’s hose is connected to either a dedicated suction line or directly to your skimmer. Suction cleaners are powered by a turbine which is spun by the force of pump’s suction. Suction cleaners are ideal for screened in pools or ones which mainly face sand and dirt with light leaf traffic.

Conclusion

Our recommendation would be to go with a Pressure Side Pool Cleaner if you already are plumbed for this type of cleaner, get large debris or get low flow from your main filter pump. We suggest a suction side pool cleaner if you are not plumbed for a pressure cleaner, have a main filter pump above ¾ HP or do not get very heavy debris. If you have any questions on which type of pool cleaner is right for you we would be happy to help, just leave a comment below.

    I have a vinyl liner in-ground 21000 gallon pool with one return port, a skimmer, and no drain. Pump motor is 2 hp. Which pool cleaner would be best for me?

    1. Matthew Simmons Avatar

      I’d use a pressure side cleaner that works of the return line, like the Kreepy Krauly Legend II Pool Cleaner – LX5000G. A pool that size should have more than one skimmer, I would think. But the return jet pressure side cleaners allow you to have a cleaner without sacrificing the function of the skimmer, or the need to add a booster pump.

    I have a new dolphin premiere doesn’t use pool system at all. Had own bags to collect what’s in pool does rocks leaves everything. So why wasn’t this one mentioned or do you not offer them

    1. Matthew Simmons Avatar

      We offer robotic cleaners but the article is focusing on cleaners that rely on your pump system. As you mentioned, robotic cleaners are self-contained and do not require suction or water pressure from the pump.

    Great information.
    Just ordered your pool guide ebook.

    To get the pressure up which pump should I go for? We have almost no circulation in our pool even if it cleans ok through the skimmer.

    Look forward to hear from you

      We have this guide on correct low water pressure: How to Correct Low Water Pressure in Your Pool System

      I’d try the steps in the guide before purchasing a higher HP pump.

    Matthew , I have 2 returns , would it be advisable to run the 360 as the only return , trying to get more pressure ?

    I just purchased a zodiac MX8 elite but could not get the correct pressure/ suction to get the recommended rotation on the wheels. I have a variable speed pump and tried adjusting the RPMs as well but could make it work. Have seen this before?

    1. Matthew Simmons Avatar

      The MX8 requires strong suction for it to work properly; your system may not be able to create the amount of flow rate it requires to work. If you have maxed out your RPMs and the cleaner does not respond, you may have to get a more conventional model like the Pool Cleaner.

    Hello Matthew,
    Unfortunately I’m stuck with a suction style cleaner (hate it). I currently have the Baracuda MX8.
    From reading your explanation above it sounds that my best option is the Polaris 360 (suction) however I can find it. Do you guys carry this cleaner?

    1. Matthew Simmons Avatar

      Juan – yes we do carry the Polaris 360, give it a look.

      1.  Avatar

        Matthew thank you for your immediate respond and the link. I was reading the specs and it says “pressure” I apologize for my ignorance I just want to double make sure It’s going to work with my system of suction. Also do you carry this in Black? It sounds like its available in black. Thank You in advance.

          The Polaris 360 works off of the return line, and not from a booster pump system. The 360 is still classified as a pressure cleaner because water is pushed through it just like a standard pressure cleaner.

          Yes, we do offer the Polaris 360 Black Max Pool Cleaner – F1B

    How to robotic pool cleaners compare to these type of pool cleaners and why would I choose a robotic over them?

    I have tile pool. I have tried a few suction cleaners. None of them can climb out of the deep end or climb walls. The tile is too slick. Would pressure side cleaner do better?

  9. Mark M. Avatar

    Can I use the suction side pool cleaner port to manually clean my pool?

    1. Matthew Simmons Avatar

      A standard vacuum hose can be installed to a dedicated suction line, just as you would a suction cleaner hose.

    I have a fiberglass insert inground pool. it has a three return jet ports, a skimmer and a bottom drain. there is also a port that does not jet or suck water. do you know what this extra port is for? I did find a conduit stubbed outside of the concrete perimeter of the pool recently while laying a patio next to the concrete. it looks as if it would lead to that extra port.
    thanks,

      It could have been for a light like a Savi Melody light. But that’s a guess.
