Robotic cleaners are a big time saver for pool owners and they work hard to get the job done. But like all equipment they do need regular maintenance and cleaning to ensure that they run smoothly and efficiently. There are many common problems that can occur with robotic pool cleaners, and most are easy to troubleshoot and fix if you know what to look for.
If a robotic cleaner is having difficulty climbing the walls of the pool it may be due to the poly vinyl alcohol (PVA) brushes not fully absorbing the water, or the cleaner may have had an issue with its internal microchip which could be out of date or damaged. In these cases it is recommended that the robot be removed from the pool water and drain, wash the unit thoroughly then allow to dry in a shaded area before returning. This simple process will help to maintain the unit and greatly extend its life.
Other common issues that can arise with robotic cleaners include the unit getting stuck on stairs or a handrail, a lack of suction, or changing direction and cleaning patterns. These issues can be fixed with the use of ladder guards, shortening the hose for entry step handrails, or by adjusting thrust jets to change the cleaning pattern. PVA brushes can be cleaned by soaking in a bucket of water to soften them. If a robot is having issues with its wheels or drive tracks, then this can be remedied by inspecting and removing any debris that has become trapped in the wheels, or by replacing the wheel if necessary. The same is true for the drive pulleys which can also be replaced if they have worn out with time.
In addition to these specific areas, it is important to understand that robotic cleaners do not work as independently as a suction or pressure side pool cleaner. Robotic cleaners operate off the pool’s filter system, and are dependent on the filtration media (typically sand, diatomaceous earth or zeolite) to remove contaminants from the pool water. As a result, ensuring that the filter media is clean and operating properly is critical for robotic cleaners to perform effectively.
Another important point to remember is that robotic cleaners typically have a higher up front cost than a suction or pressure side pool cleaner. As such, they can be a more significant investment for some clients. This is why it is important to take the time to explain the advantages of owning and maintaining a robotic cleaner, as well as what is covered under the manufacturer’s warranty. This can save your clients money in the long run, and give them peace of mind knowing that their investment is protected.
