How to Remove Algae from Swimming Pool Walls with Robotic Pool Cleaner



Algae growth on swimming pool walls can be a persistent challenge for pool owners, affecting the appearance and cleanliness of the pool environment. This guide will explore practical methods for removing algae from pool walls using advanced robotic pool cleaners.

Understanding the Types of Algae on Pool Walls

When dealing with algae infestations on pool walls, it is critical to identify the specific types of algae present. Common types include green algae, black algae, and mustard algae.

 1. Green Algae

The most common type found in pools is green algae, which appears as green spots or patches on the walls. It thrives in sunlight and can quickly spread if not addressed promptly.

 2. Black Algae

 Recognizable by its dark, black spots with a hard protective outer layer, black algae roots deeply into porous surfaces like pool walls. Removal of black algae can be challenging due to its resilient nature.



3. Mustard Algae

 With a yellowish-brown color, mustard algae often manifests as slimy deposits on pool walls. This algae is resistant to standard chlorine levels and may require specialized treatment for complete eradication.

Traditional vs. Modern Cleaning Approaches

Here is an outline of how to remove algae from pool walls traditionally, as well as with a modern robotic pool cleaner:

Traditional Method

  1. Brushing:

Utilize a firm-bristled brush to scrub the algae patches present on the pool walls, using circular motions to dislodge the algae from the surface.

  1. Manual Vacuuming:

After brushing, manually vacuum the loosened algae debris from the pool walls.

Ensure thorough extraction to prevent algae from spreading.

  1. Shock Treatment:

Apply a pool shock treatment to kill the remaining algae spores.

Read the manufacturer's instructions first for proper dosage use.

  1. Algaecide Application:

Use an algaecide to prevent algae regrowth.

Choose a suitable algaecide based on the type of algae present in your pool.

Robotic Pool Cleaner Method:

  1. Set Up the Robotic Pool Cleaner

Place the robotic pool cleaner in the water, ensuring proper connection and activation for optimal performance. With a Beatbot robot, you can select the most suitable mode accordingly to perform the cleaning best. 

  1. Let the Robotic Cleaner Operate

Allow the robotic pool cleaner to navigate the pool walls autonomously.

The cleaner will climb and scrub the walls using specialized brushes and cleaning mechanisms. Unlike other products with wandering performance, Beatbot AquaSense Pro smartly navigates along the pool wall, forming a unique N-shaped path to thoroughly scrub every inch without leaving any space untouched. 

  1. Regular Maintenance

Establish regular cleanings with the robotic pool cleaner to prevent algae buildup.

Maintain proper water chemistry levels and filtration for optimal cleaning performance.

Using a robotic pool cleaner for algae removal offers efficient and hands-free cleaning of pool walls, while traditional methods involve manual labor and more time-consuming processes. Both approaches aim to achieve algae-free pool walls and maintain a clean swimming environment.

Features of Cleaning Pool Walls with a Robotic Pool Cleaner

Unlike the straightforward cleaning process of the flat and smooth pool floor, cleaning the pool wall with a robotic pool cleaner demands greater precision and attention to detail in the following aspects:

1. Climbing Ability

Vertical Surface Navigation: Robotic pool cleaners have climbing abilities to scale pool walls effortlessly. This feature ensures comprehensive coverage of all wall surfaces, including hard-to-reach areas.

2. Scrubbing Brushes

Algae Removal: Robotic pool cleaners have high-quality scrubbing brushes designed to dislodge and remove algae deposits from pool walls. These brushes effectively agitate the surface, loosening stubborn algae for thorough cleaning.

With the unique design of 4 brushes with differential speed, Beatbot AquaSense Pro can remove the algae more efficiently and thoroughly than other brands.

3. Waterline Scrubbing

Waterline Maintenance: Some high-end products, like Beatbot robotic pool cleaners, feature waterline scrubbing capabilities. This function helps prevent waterline buildup and algae formation, maintaining a clean and polished appearance.

4. Different Cleaning Mechanisms: 

Cleaning pool walls may require different cleaning mechanisms compared to cleaning pool floors. The design and operation of the robotic pool cleaner need to be optimized for wall cleaning to ensure the efficient removal of debris and algae. Beatbot AquaSense Pro will form the unique N-shaped pattern when cleaning the pool wall and the S-shaped pattern when cleaning the pool floor, utilizing the most efficient cleaning paths to eliminate overlaps and ensure a spotless pool with no missed areas.
