We are well aware of the usefulness of pool robots for cleaning the bottom of the pool, but what about the vertical walls? Few owners know it, but some robots are designed to climb the walls of the pool and ensure its complete cleaning. This feature, long reserved for high-end models, has now become more widespread. But not all robots are capable of it. So which models can climb? Why is this important? And how do you know if your robot is suitable? Here's everything you need to know about the ability of pool robots to climb walls... and clean them properly.
Why cleaning the walls is essential
The vertical walls of a swimming pool are often neglected, but they are a real deposit area for impurities. Algae, bacteria, sunscreen residues or atmospheric pollution quickly cling to them, forming greasy or slippery areas. If they are not cleaned regularly, these impurities can affect the water balance and cause algae to proliferate. A robot capable of climbing walls eliminates these risks by effectively brushing all submerged surfaces. This also reduces the use of chemicals and the need for manual brushing. Wall cleaning is therefore much more than a detail: it is an integral part of the overall and consistent maintenance of the pool. In addition, the most efficient models also reach the waterline, where fatty residues accumulate - an area that is often difficult to treat by hand.
Which robots are capable of climbing walls?
Not all pool robots can climb walls. This feature is generally reserved for electric models, which are more powerful and better equipped than hydraulic or manual versions. To climb, a robot must be equipped with specific motors, active brushes (often made of foam or with spikes) and an efficient traction system (tracks or drive wheels). Tilt sensors and intelligent weight management are also essential to maintain grip on vertical surfaces. Well-known brands such as Dolphin Maytronics, Zodiac, Hayward and Aiper include this feature in most of their mid-range and high-end models. With BEATBOT, robots such as the
AquaSense 2 Ultra or the
AquaSense Pro can easily climb walls, clean actively and descend safely after each pass. If you want to make sure that your robot climbs, check this information in the technical data sheet of the model - don't rely solely on the external appearance.
How does a robot climber work in a swimming pool?
A robot climber works in three stages. First, it moves along the bottom and detects the wall using its tilt sensors. Then it activates its motors to begin a gradual ascent by adhering to the walls, often thanks to a vacuum created by the suction of the water. Rotating brushes then scrub the vertical surface to remove impurities, while the sucked-up water passes through the robot's internal filtration system. Some models stop just before the water line, while others clean it too. The cycle continues until all the walls have been treated. The robot then descends on its own, or returns to the bottom before moving on to another area. This movement is fully automated. Thanks to mapping or optimised movement algorithms, the most advanced models can determine which areas have already been treated and avoid redundant passages. This is therefore a real embedded technology, a far cry from the first random-movement robots.
Limits to be aware of before choosing
Although many robots are able to climb walls, some pools have features that can complicate their task. Slippery surfaces (smooth tiles, very flexible liner) or steeply sloping walls can be a problem for some models. Similarly, obstacles such as stairs, complex nooks and sharp corners are not always cleaned properly, even by a climbing robot. Maintenance of the robot itself is also essential: dirty or worn brushes reduce grip, as does an overfilled filter. To ensure efficient climbing, it is therefore recommended that the device be serviced regularly. In addition, wired robots must have enough cable length to reach opposite walls. Wireless models such as BEATBOT offer more freedom here, but their autonomy must be well managed to cover the entire pool. Finally, if you have a mirror or infinity pool, not all robots are suitable. It is best to check compatibility with this type of pool.
The advantages of a complete bottom and wall cleaning
A robot capable of cleaning the walls guarantees you consistent cleanliness over the entire immersed surface of your pool. This results in clearer water, a more stable chemical balance and a reduction in manual interventions. You also reduce wear and tear on your filtration system, since impurities are removed before reaching the bottom or the skimmers. Cleaning the walls is also an excellent way of delaying the appearance of algae and preventing fouling of the water line. In addition, a robot skimmer such as the
iSkim Ultra from BEATBOT can clean the surface, capturing the floating debris that accumulates there. By combining these solutions, you cover the entire pool: surface, bottom, walls and water line. This ensures a continuously clean pool, without having to spend your weekends on it. This level of automation transforms maintenance into an ultra-simplified routine, while maintaining a high level of hygiene for bathers.
Choosing the right robot for your needs
The choice of a robot cleaner should be based on several criteria: size and shape of the pool, type of surface, budget, frequency of cleaning, etc. For a small pool or occasional use, a model that only cleans the bottom may suffice. But as soon as your pool exceeds 25 m² or has complex walls, a robot capable of climbing them becomes a real bonus. Models such as the BEATBOT AquaSense 2 Pro, the Zodiac Alpha, or certain Dolphin robots offer very good grip and reliable cleaning of the walls. Choosing the right equipment also depends on your tolerance for effort: if you want to automate maintenance as much as possible, opt for a 3-in-1 model that covers the bottom, walls and waterline. Finally, don't forget to check the connectivity options, how easy the filter is to clean, the manufacturer's warranty and the availability of spare parts. A well-chosen robot quickly becomes indispensable, and radically transforms your relationship with pool maintenance.
A robot that climbs means maintenance that is a breeze
Having a pool robot that can climb walls means freeing yourself from one of the most tedious maintenance tasks. You save time, chemicals and ensure healthier water day after day. This ability to clean the walls, often invisible but incredibly dirty, makes all the difference in the durability of your pool and the pleasure of swimming. BEATBOT robots, such as the AquaSense 2 Ultra, perfectly illustrate this new standard, where technology gives way to comfort. By combining automated cleaning, efficiency in all respects and easy maintenance, robot cleaners are no longer a luxury, but a matter of course. All you have to do is choose the right model, let it do the work... and enjoy a spotless pool, from the bottom to the waterline.
