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.

      Every pump and filter system has a suction and a pressure side. A suction cleaner can be hooked into the skimmer to run off your main pump. There are pressure side cleaners that can run off one of a return line, so you do not need a dedicated booster pump.

    Hello-
    We just bought a house with a zodiac pool, it has a CL460 cartridge filter, spectra JHPU/SHPU pump and has an energy filter. We were told the energy filter would work with the 380 and no booster pump was needed? We tried to hookup our polaris 380 to the side wall, but it appears the dedicated line doesn’t suck, just blows water out. The vac will move around the pool when installed in the side wall, it sucks up large stuff in the bag, but not sand or small debris? We tried to hook it into the skimmer, but it doesn’t move at all when we hook it up through the skimmer. What are we doing wrong? Do we need a different vacuum? Any info is appreciated as we just want to get the pool clean. TIA.

      The Polaris 360 is a pressure-side cleaner; it is unique from most other Polaris models because it runs off the return line instead of a dedicated booster pump system. The 380 requires a booster pump. So if the previous owner was using the cleaner and they do not have a booster system, you have the 360, not the 380.

      I’d refer to the Polaris 360 owner’s manual troubleshooting section to begin with. The troubleshooting begins on page 12.
