How Does an Automatic Pool Cleaner Work?

24 minutes read

An automatic pool cleaner is designed to clean the pool by removing debris and dirt from the pool floor, walls, and surface. It operates using various mechanisms that allow it to move around the pool and collect the debris efficiently.


One common type of automatic pool cleaner is the suction-side cleaner. It attaches to the pool's suction inlet or skimmer and utilizes the pool's filtration system to operate. The cleaner is connected to a hose that is usually attached to the skimmer or a dedicated suction line. As water is drawn through the hose, it creates a suction force that propels the cleaner.


The cleaner typically has a disc or a set of wheels that allow it to move freely across the pool floor. It also has brushes or scrubbers underneath that help remove dirt and algae. Some models may have additional features like a bag or basket to collect larger debris before it reaches the pool's filtration system.


Another type is the pressure-side cleaner. It connects to a dedicated pressure line and uses the pool's water pressure as a propelling force. The pressurized water is responsible for driving the cleaner around the pool. This type of cleaner generally has its own debris bag or filter to trap leaves, bugs, and other debris.


Robotic pool cleaners are also popular. Unlike the suction-side or pressure-side cleaners, they are entirely independent of the pool's filtration system. They have their own motor and filter system, and some may even have advanced features like remote control or programmable cleaning cycles. Robotic cleaners move randomly around the pool, using brushes and suction power to collect dirt and debris before depositing it into their internal filtration system.


In all cases, the pool cleaner's movement is usually random or patterned to ensure thorough cleaning of the entire pool surface. The various mechanisms, including brushes, scrubbers, or suction, work in coordination to dislodge and vacuum the dirt, leaves, and other debris, keeping the pool clean and clear for swimmers to enjoy.


Overall, automatic pool cleaners provide a convenient and efficient way to maintain the cleanliness and hygiene of pools, making pool maintenance easier and less time-consuming.

What is the purpose of an automatic pool cleaner?

The purpose of an automatic pool cleaner is to clean and maintain the cleanliness of a swimming pool without the need for manual labor. It is designed to remove dirt, debris, leaves, and other contaminants from the pool surfaces, including the floor, walls, and waterline. It helps to keep the pool water clear, hygienic, and free from any harmful substances. Automatic pool cleaners save time and effort for pool owners by constantly working to clean the pool, allowing them to enjoy a clean and healthy swimming experience.


How does an automatic pool cleaner prevent getting stuck on obstacles?

An automatic pool cleaner usually employs various mechanisms and techniques to prevent getting stuck on obstacles in a swimming pool. Here are a few common methods:

  1. Bump and Reverse: Many pool cleaners are equipped with sensors or mechanical systems that detect obstacles, such as walls, steps, or ladders. When an obstacle is encountered, the cleaner changes its direction by reversing and then continuing in a different path, ensuring it doesn't stay stuck.
  2. Anti-Tangle Devices: Some pool cleaners have anti-tangle devices, like swivel cords or chains, which prevent the cleaner's cord from tangling around obstacles. This technology allows the cleaner to navigate freely without entangling itself, reducing the chances of getting stuck.
  3. Intelligent Navigation: Advanced pool cleaners often employ built-in microprocessors or navigation technologies like gyroscopes, accelerometers, or intelligent software algorithms. These technologies enable the pool cleaner to scan and map the pool's layout, calculate the optimal cleaning path, and avoid obstacles automatically.
  4. Climb and Overcome: In the case of raised obstacles, such as pool steps or walls, certain pool cleaners are designed to climb and overcome them. They have features like pivoting wheels, adjustable pressure, or powerful suction to ensure the cleaner can easily ascend the obstacle and continue cleaning without getting stuck.
  5. Remote Control: Some automatic pool cleaners come with remote controls, allowing the user to guide and maneuver the cleaner to prevent it from getting stuck on obstacles. This is particularly useful when dealing with irregularly shaped or intricate pools where obstacles may be positioned in unexpected locations.


It's important to note that while automatic pool cleaners are generally designed to avoid getting stuck, occasionally, certain unique obstacles or complex pool configurations might pose challenges. In such cases, manual intervention or adjustments may be necessary to free the cleaner.


How to select the appropriate settings for an automatic pool cleaner?

Selecting the appropriate settings for an automatic pool cleaner depends on various factors such as the type and size of your pool, the level of debris and dirt present, and the specific features and controls of your pool cleaner. Here are some general steps to help you select the appropriate settings:

  1. Read the User Manual: Start by thoroughly reading the user manual of your automatic pool cleaner. It will provide specific instructions on how to set up and adjust the settings based on your cleaner's features and controls.
  2. Consider Pool Type and Size: Determine the type of pool you have (inground or above ground) and its size. Different pool cleaners may have specific settings or adjustments based on pool type and size.
  3. Assess Debris and Dirt Levels: Observe the level of debris and dirt present in your pool. If you have a pool with lots of trees or nearby foliage, or if you regularly host gatherings, you may require more intensive cleaning settings.
  4. Adjust Suction Power: Some pool cleaners have adjustable suction power settings. If your cleaner allows this, start with a low suction power and gradually increase it until you achieve the desired cleaning performance without causing any damage to the pool or cleaner.
  5. Set Cleaning Schedule: If your pool cleaner has a programmable timer or scheduling feature, determine the optimal times for it to run. Factors such as sunlight exposure, pool usage, and filtering system efficiency can influence the suitable cleaning schedule.
  6. Test and Monitor: After adjusting the settings, run the automatic pool cleaner for a trial period. Monitor its performance and assess if it effectively cleans the pool without any issues. Observe any changes needed and make further adjustments if required.


Remember, the appropriate settings may vary based on the specific manufacturer instructions and the model of your automatic pool cleaner, so always consult the user manual for the most accurate guidance.


What is the impact of an automatic pool cleaner on water chemicals?

The impact of an automatic pool cleaner on water chemicals can vary depending on the specific cleaner and its operation. However, there are several general impacts to consider:

  1. Distributes chemicals: Automatic pool cleaners help in distributing pool chemicals more efficiently. As they move around the pool, they can mix the water and help spread the chemicals more evenly, ensuring better circulation and overall water chemistry.
  2. Reduces chemical consumption: By keeping the pool clean and removing debris, an automatic pool cleaner can help lessen the load on the pool filtration system. This can subsequently reduce the demand for certain chemicals, such as chlorine, as cleaner water requires less chemical treatment.
  3. Alters chemical balance: Some pool cleaners, especially those using suction or pressure, can affect the water chemistry to a certain extent. They may cause a slight dilution of the pool water, which can affect pH, alkalinity, and other chemical levels. Regular monitoring and adjustments may be necessary to maintain proper water balance.
  4. Alleviates stagnant areas: Automatic pool cleaners often reach areas that may not be well circulated by the pool's filtration system alone. By improving water circulation, they can minimize the formation of stagnant water pockets, which in turn helps to prevent the growth of algae and bacteria.


Overall, the impact of an automatic pool cleaner on water chemicals is generally positive as they enhance water circulation and cleanliness, leading to a more balanced and well-maintained pool. However, it is essential to regularly monitor water chemistry and make adjustments as needed to maintain optimal levels.


What is the average cost of an automatic pool cleaner?

The average cost of an automatic pool cleaner can range from approximately $200 to $1,500, depending on various factors such as brand, features, type (suction-side, pressure-side, or robotic), and the size and complexity of the pool.
