Pool season comes with all the fun times and a lot of work too. Cleaning out the leaves and other debris, ensuring optimum swimming pool chemistry, and regular cleaning can take a toll on both your time and money. If you employ professional pool cleaners, the cost of maintaining your pool goes up further. This is where an automatic pool cleaner can come in handy.

Not all automatic pool cleaners are the same. And the best one for you entirely depends on the type of pool you have, the plumbing system, and your budget. There are three different types of automatic pool cleaners. The pressure side pool cleaners, the suction side pool cleaners, and the robotic pool cleaners. Each one works with a different mechanism and comes with its own set of pros and cons.

Understanding the pool’s pumping system

Before we delve further into these, here’s a quick round-up of how the swimming pool circulation works. The pool pumping system works similar to the circulatory system of our bodies. The heart pumps wherein blood, and clean blood is returned to the body. The pool pumping system works similarly. Skimmers draw the water through the pool while a centrifugal pump drains it. Large debris is removed by the basket in the skimmer and stops it from entering the impeller in the pump.

This water is further cleaned by force from the pump’s impeller. The clean water is then returned to the pool. Some pool circulation systems also treat and heat the clean water before it goes back in the pool. With an idea of how the pool pumping system works, it will be easier for you to decide which type of pool cleaner is best for you. We are going to talk about and review the top suction side pool cleaners in this article. And arm you with enough information to buy just the right one and how to care for it.

What are suction-side pool cleaners, and how do they work?

Suction-side pool cleaners are the most popular as well as the least expensive compared to the other two types. The first automatic pool cleaner ever used was a suction-side one. As the name suggests, it works with the suction action of your pool’s pumping system. The suction power of the pool pump, through which water passes through the filter, propels the suction side pool cleaner and gives it motion.

The cleaner moves around the pool in a random path and extracts the dirt and debris. A hose is attached to a hole below the skimmer basket. Some pools also have dedicated suction cleaner lines. It is usually located somewhere in the middle of the pool’s length. With this dedicated line, you can directly plug in the cleaner to the wall fitting.

Once the hose is attached, the pool’s pumping system creates suction under the cleaner. Think of it as an underwater vacuum cleaner that does not require you to move it around. As the cleaner moves across the swimming pool, it catches debris, dirt, and more. These get sucked through the pipe, the hose, and collects at the pump’s skimmer basket. If the waste is really small, it might even pass through the skimmer to the filter.

Advantages of a suction-side pool cleaner over pressure-side and robotic cleaners

  1. They are the easiest to install
  2. Have fewer moving parts hence require less maintenance
  3. Most models climb and clean walls easily
  4. Works very well with small debris
  5. Does not require any additional booster pumps
  6. Lower electricity consumption

Points to keep in mind when selecting a suction-side pool cleaner

  1. Size and type of pool: The type of pool you have and its size are the foremost things to consider when buying an automatic pool cleaner. Suction-side pool cleaners are best suited for small and medium-sized pools. You will also need to check if a cleaner is meant for in-ground or above-ground pools. Most suction-side cleaners work with all kinds of surfaces including vinyl, fiberglass, and concrete. We would still advise checking for your pool surface type.
  2. Length of the hose: Most cleaners come with a hose that works well with any medium-sized pool. But a tube that is too long can lead to tangling, and a one tad bit short can impair cleaning the entire pool. A lot of products these days come with a detachable hose that you can assemble based on your needs. But we suggest you pick the one which is suitable for your pool size and quickly reaches the end of the pool from the skimmer. Do check if your favorite model has an option to buy a longer one.
  3. Price: While you might be spoilt for choice with different types and brands of pool cleaners available in the market. Pick one that suits your budget. A pool cleaner is not a one-time expense and will incur a few other costs over time, including maintenance, power, and more. Suction-side pool cleaners are the most affordable and have low maintenance costs too. So, once you decide on choosing a suction-side cleaner, shortlist the ones that are within your budget.
  4. Durability: Do check for the warranty offered by the manufacturer. A good rule of thumb is to go for a cleaner with a more extended warranty from the manufacturer.
  5. Debris: If your pool collects a lot of large debris a suction-side pool cleaner will need more care, and your skimmer too will bear the impact. Any suction-side pool cleaner will work well for smaller debris. If you live in an area with a lot of leaves, acorns, and other large debris frequently accumulating in your pool, invest in a cleaner with more powerful suction. You can also get a pool screen to ease the pressure on the cleaner and your pumping system.

How to maintain and care for your suction-side pool cleaner

With fewer moving parts caring for a suction-side pool cleaner, the cleaner is more uncomplicated and more comfortable. Just keep in mind the following easy tips to make your suction cleaner work well and last longer.

  1. When installing a suction cleaner, always start with a clean filter.
  2. Always remove the pool cleaner before you plan to do a chemical shock.
  3. Regularly check all inlet for any trapped or accumulating debris.
  4. If reinstalling, make sure the plumbing line has been flushed.
  5. Reduce wear and tear by running the pool cleaner only as long as needed.
  6. Disconnect the hoses before storing them and always lay them flat.
  7. Store both the cleaner and the hose in a dry shade/cover away from the sun.
  8. Always disconnect the pool cleaner while swimming or when you are cleaning or backwashing your pool filter.
  9. Maintain a clean pool pump and ensure that your skimmer basket, pool filter, and your pump basket are cleaned before each cleaning cycle.
  10. Check all parts regularly and replace them as needed.

While you take time to decide which automatic pool cleaner to go for, it is essential to ensure a healthy and clean pool. Both cleaning and maintaining the chemical balance is necessary to ensure your pool is clean and safe. A good practice is to check the pH and chlorine levels daily.

Safe and happy swimming!
