How Automatic Pool Cleaners Work?

The function of an all automatic pool cleaner is to clean debris and dirt from swimming pools automatically. With an automatic pool cleaner, pool owners do not have to pass through rigorous work to clean their pools. Also, maintaining this machine is more comfortable.

If you are planning to own an automatic pool cleaner, you will want to know how it works, and hence, the purpose of this article. This article is to give you an insight into how automatic pool cleaners work. However, it is important to mention that these cleaners are of three types, which we will examine. They are:

  • Suction-Side Pool Cleaners
  • Pressure Side Pool Cleaners
  • Robotic Pool Cleaners

The Suction-Side Automatic Pool Cleaner & Why You Need It

The suction-side automatic pool cleaner is one of the simplest methods of cleaning the swimming pool. It is quite easy to install and cost-effective.

Here are reasons to choose this system:

  • Simple installation process

The suction-side automatic pool cleaner is the simplest easy-to-install model of all types of automatic pool cleaners. It doesn’t require any special skills or tools. Within a few minutes, you’re good to go.

  • Low cost

If you need a pool cleaner that is highly cost-effective and won’t require you to break the bank to buy it, the suction-side pool cleaning system is the way to go.

  • Highly efficient

The suction-side pool cleaner is also popular among homeowners and managers of restaurants and gym centers for its efficiency and incredible performance.

How the Suction-Side Automatic Pool Cleaners Work

This is the most common type of automatic pool cleaner, and it is widely adopted for above-ground pools. This is an underwater vacuum that gets its name from how the pool pump generates suction. The cleaner will clean the entire pool by moving around the pool in a specified pattern.

To use the suction-side automatic cleaner, you have to attach it to the existing wall skimmer and watch as its moving part cleans your pool. The cleaner is designed to work when your pool pump is running, which necessitates that to use the cleaner, you’ll to keep your pool pump on.

When this cleaner picks debris and dirt, it drops them in your filter system. Using this machine helps to reduce your effort and time of cleaning the surface of your pool.

If your pool contains lots of debris, it is likely that your pool basket will get filled with debris while the cleaner is working. To prevent this from happening, simply attach the in-line leaf canister. Suction pool cleaners are ideal for pools in desert climates as they are great clearing sand.

Pressure-Side Automatic Pool Cleaner & Why You Need It

Why should you choose the pressure side automatic pool cleaners? There’s a lot to admire about this model of cleaners.

  • Even water distribution

One great benefit of the pressure-side auto pool cleaners is that it dispenses filtered water everywhere around the pool. This water is evenly shared so that no part of the pool is left dehydrated. 

  • Doesn’t clog water passage

The second feature to look for when using the pressure side automatic pool cleaners is that it does not clog up the water filter passage with debris. The skimmer is always free of dirt or composite

  • Improves water circulation

Again, water circulation in a pressure-side automatic pool cleaner is quite smooth and seamless. Water gets to every part with an almost equal volume

  • Efficient and fast water flow

Water dispensation is fast and efficient when it comes to the use of pressure side automatic pool cleaners.

How the Pressure-Side System Works

This comes with a hose that should be attached to the pool return line. The force of the water that comes from the return line gives the cleaner the force it needs to move around your pool’s surface. While moving through the surface, it creates a vacuum to suck dirt and debris from your pool and deposit them into a bag dedicated to dirt. The name of this cleaner comes from how it depends on the pressure of the water coming from the return line.

Since the cleaner might need more pressure than what is coming from the return line (the hole through which water enters back the pool), you might need to attach a booster pump to send more volume of water.

With this cleaner, you can still go on with your surface skimming action.

Robotic Automatic Pool Cleaners & Why You Need It

Using robotic pool cleaners comes with a lot of benefits. Many homeowners prefer this type of automatic swimming pool kits for several different reasons.

  • Free-standing filtration

Everyone will love this amazing model for its multiple advantages. It features a self-sufficient filtration process. This helps to take off or reduce the wear and tear that typically affects your cleaner’s filter and pump.

  • Fast and quick

When it comes to speed and quick action, robotic pool cleaners top the list. It offers the fastest process for cleaning your swimming pool, with a quick turnaround.

  • Custom  Features

Depending on the unit you are using, the robotic pool cleaners allow users to customize the cleaning. This is because it comes with its own filtration system. You can also remote control the cleaners, at ease

How the Robotic Automatic Pool Cleaning System Works

This type of cleaner comes with its own filtration system that is used as a secondary filter. Using a cleaner with its filtration system, you do not need to attach it to an external filter system.

You can control this cleaner from a distance using a remote control system, and it works using a 110-volt electrical supply with a transformer to step the power down. The cleaner works automatically to clean your pool’s debris and dirt and deposit them in a built-in bag. 

Robotic pool cleaners are energy-efficient, as they can save up to 94% of the energy consumed in most pressure cleaners.

What to Know About Automatic Pool Cleaners

An automatic pool cleaner reduces the time a pool owner or maintenance team spends cleaning a pool. It works by removing dirt and debris from your pool with little effort. This ensures that the algae in your pool are reduced, which allow you to spend less on chemicals.

Choosing the right automatic pool cleaner for your pool depends on several factors and features. You have to consider the position of your pool. For instance, you need to know whether your pool is above the ground or in-ground.

When is the pool above ground?

One of these features is whether your pool is above-ground or in-ground.

Here are attributes to consider when choosing the best cleaner for your pool:

  • Do you want to clean the bottom of your pool
  • Has your pool grown algae that your cleaner needs to scrub the walls
  • Is your pool designed with a beach entry
  • Do you want an energy-efficient pool cleaner
  • Do you need your pool cleaner to come with a remote control feature?

The type of cleaner that is best for your pool also depends on which type of pool you own: in-ground or above-ground.

Here are some of the benefits of pool cleaners:

  • They are great for beach entry pools
  • Designed for beach entry pools

Frequently Asked Questions

Q: Do automatic pool vacuums work?

Absolutely! Typically, automatic pool cleaners,—whether it’s the suction-side, pressure-side, or the robotic automatic pool cleaners — work effectively when your pool is running. What they do is to pick up debris or dirt and drop it inside your pool’s water filter system. They clean up the pool while also reducing the skimming on the surface of your pool.

Q: What is the lifespan of automatic pool cleaners?

Depending on the brand or model you buy and the kind of maintenance you provide, automatic pool cleaners can last between 3 to 5 years. Some models of robotic pool cleaners can last for up to 8 years. They do not feature replacement parts, meaning you have to replace the whole system once it lives its lifespan.

Q: How frequently should I run a robotic pool vacuum?

It all depends on how often swimmers use the pool. Usually, you should run your robot pool vacuum once a day, or at most daily. However, if swimming doesn’t often take place in the pool, once a week or month is not a bad interval for running.
