Whether you love lounging in crystal-clear water or just want to avoid endless hours of scrubbing, a good pool cleaner can make all the difference. But with so many options out there, how do you know which one’s best for your pool?

Suction and pressure pool cleaners are the two heavyweights in the cleaning game, but they work in very different ways. Whether you’re dealing with pesky leaves or stubborn dirt or just want to keep your pool looking perfect with minimal maintenance, we’ve got you covered.

About Suction Pool Cleaners

Attached directly to your pool's filtration system, suction pool cleaners run utilizing the suction power from your pool pump. Sucking up dirt and debris as they go, they move around the pool floor.

Advantages of Suction Pool Cleaners

  • They’re among the most affordable options on the market.
  • Setting them up is a breeze—just connect them to the pool skimmer or a dedicated suction line, and you’re good to go.
  • Excel at picking up small particles like sand, silt, and dirt, leaving the pool floor spotless.
  • Less risk of breakdowns or the need for frequent repairs because of fewer moving parts.

Disadvantages of Suction Pool Cleaners

  • Put added strain on the pump and lead to more frequent filter cleanings, because they work off the pool’s filtration system.
  • Leaves, twigs, and larger debris are often too much for these cleaners to handle effectively.
  • Pool circulation can drop slightly because the suction cleaner pulls power away from the main pump system.

On Pressure Pool Cleaners

Pressure pool cleaners run on water pressure from your pool’s return line. While some models run with the primary pump, others require a booster pump for more power.

Pros of Pressure Pool Cleaners

  • They easily pick up leaves, acorns, and other big debris.
  • These cleaners have their own debris bag, which keeps dirt out of the pool’s filtration system and reduces filter maintenance.
  • With strong propulsion, pressure cleaners are great for larger pools or those with unusual shapes.
  • Built to last, handling tougher cleaning jobs without frequent breakdowns.

Cons of Pressure Pool Cleaners

  • Pressure cleaners are more expensive upfront, and models needing a booster pump add to the expense.
  • Booster pumps increase electricity usage, which may raise utility bills over time.
  • Unlike suction cleaners, installation can be time-consuming, especially for models that require a booster pump.
  • Even though these cleaners don’t rely on suction, they can still contribute to pump wear due to the added pressure demands.

Suction vs. Pressure Pool Cleaners: How to Choose Based on Use Cases

Deciding between suction and pressure pool cleaners depends on your pool’s conditions and what matters most to you. You can consider some typical scenarios:

  • Suction cleaners are a great budget-friendly choice for those who want solid cleaning without breaking the bank. They’re perfect for pools with light debris.
  • If your pool is always collecting leaves, twigs, or bigger debris, a pressure cleaner is the way to go. Their debris bags keep everything contained and prevent clogging your pool’s filtration system.
  • If keeping electricity costs low matters to you, suction cleaners are the better pick. They hook up directly to your pool pump, so you don’t need any extra equipment like a booster pump.
  • For larger or oddly shaped pools, pressure cleaners have the power and versatility to get the job done. They’re built to clean those tricky spots with ease.
  • If you’d rather spend less time cleaning the filter, pressure cleaners might be your best bet. Their separate debris bags help reduce filter wear and tear, making maintenance less of a hassle.
