How to keep your pool walls really clean?
The walls of your swimming pool are much more than just submerged surfaces. They play a crucial role in the overall hygiene of your pool. However, they are often neglected in favour of the bottom or the surface. The result: algae deposits, greasy film, impurities To keep a pool sparkling clean, it is essential to adopt a targeted strategy for cleaning the walls. This article explains the actions, tools and equipment you need to achieve this without excessive effort. Whether you clean manually or with a robot, here you will find solutions for perfectly spotless walls.
Why walls accumulate so much dirt
Swimming pool walls are constantly exposed to various pollutants: dust, pollen, insects, sunscreen, saliva, plant debris Without regular maintenance, they become a breeding ground for algae and the formation of a greasy biofilm. The latter settles more particularly on the waterline, a critical area that is too often forgotten. Even if the water appears clear, dirty walls can unbalance the chemistry of the water and cause over-consumption of treatment products. This is why it is essential to monitor these areas regularly, especially in periods of high heat or after frequent swimming. Targeted cleaning of the walls can prevent many problems and extend the life of the pool.Manual cleaning, an accessible but limited solution
Manual cleaning with special brushes is still an economical and effective solution, especially for small pools or above-ground pools. It allows you to target critical areas and eliminate the first traces of dirt. There are several types of brushes: soft ones for liners, harder ones for shells or tiles. Some can be attached to a telescopic pole for optimal comfort. Nevertheless, this method requires time and regularity, and does not guarantee as uniform a cleaning as a robot. It quickly becomes restrictive in large swimming pools. To go further, many opt for an automated solution to delegate this tedious task without loss of efficiency.Wall-climbing cleaning robots
Pool robots capable of climbing walls and cleaning the waterline are now essential for those who want effortless and efficient maintenance. These robots generally have powerful motors, rotating brushes and intelligent sensors to detect the walls and cling to them without slipping. Top-of-the-range models such as those from Dolphin Maytronics, Zodiac and Hayward are designed for complete pool coverage. In terms of innovation, the BEATBOT AquaSense Pro stands out for its ability to clean the bottom, sides and waterline in a single autonomous cycle. A valuable time saver for optimal hygiene, without manual intervention.The importance of brushing the waterline
The waterline is the area most exposed to impurities, as it concentrates all the floating elements on the surface that stick to it: grease, sunscreen, dust, etc. It quickly forms an unsightly ring that is difficult to remove if the deposit is left to settle. Manual brushing once a week is recommended, but the ideal solution is a robot equipped to clean it actively. Some models have specific side brushes to scrub this sensitive area. Regular cleaning of the water line also helps to preserve the aesthetics of your pool and to limit the proliferation of micro-organisms that are invisible to the naked eye but harmful in the long term. A good chemical balance to avoid deposits Well-balanced water plays a key role in keeping the walls clean. If the pH is too high, limescale can build up on surfaces, making cleaning more difficult. Conversely, water that is too acidic can weaken coatings. It is essential to maintain a pH between 7.2 and 7.4 and to regularly check the levels of chlorine, alkalinity and stabiliser. The use of a flocculant or clarifier can also help agglomerate microparticles for more effective cleaning. Well-managed chemicals, combined with a high-performance robot or regular manual maintenance, guarantee walls that are always clean and without unnecessary effort.The role of skimmers and surface cleaning
Floating impurities are often responsible for deposits on the walls, especially near the waterline. To prevent their accumulation, a good surface filtration system is essential. Integrated or floating skimmers collect leaves, insects and oils before they stick to the walls. Hybrid solutions such as iSkim Ultra by BEATBOT combine the advantages of a robot cleaner and a mobile skimmer, ensuring continuous collection of floating debris. In addition to a robot climber, this tool maximises the general hygiene of the pool while limiting the appearance of dirt on the walls. An ideal two-in-one solution for demanding owners. Keeping the walls perfectly clean is not just a question of aesthetics, it is also essential for the health of the water and bathers. By combining a suitable robot such as the BEATBOT AquaSense Pro, a chemical control routine and a good surface filtration system, you create a healthy environment that is pleasant to maintain. Even if manual cleaning is still useful at certain times, automation saves time, chemicals and wear and tear on equipment. Brands such as BWT, Bestway, Aiper and Kokido offer a variety of solutions to suit every type of pool and budget. The important thing is to identify your real needs so you can invest in the most appropriate equipment. The result: clean walls, crystal-clear water and a pool that is always ready for swimmers.Published on 07/04/2025
