A robotic cleaner is a great addition to any pool, but like anything, it needs to be cared for properly in order to maintain optimal performance. If the pool cleaner seems to be acting up or is not as efficient as in the past, there are a few simple troubleshooting tips that can help determine what might be causing the problem and get it fixed right away.

Robotic pool cleaners are completely independent of the main pool and pump system. They suck water in through a self-contained filter bag, run that water through their internal motors and spit the clean water back into the pool. This is why they are so much easier to repair and maintain than pressure-side or suction-side cleaners, which must rely on the pool's existing pump to work.

It may be as simple as a clogged or faulty wheel on the cleaner, a broken brush or a blocked vent. This is one of the reasons why it is so important to regularly inspect all the parts of a cleaner for wear and tear. If any parts are damaged or showing signs of wear, it is best to replace them immediately to avoid further damage.

The cleaner could also be flipping over, which can usually be remedied by adjusting the handle position or making sure the device is balanced. It is also important to check the cable for any damages or entanglements that may be impeding the cleaner's movement (this is not an issue with cordless robotic cleaners, such as the Water TechniX SoniX).

A common problem is that the hose of the robot gets stuck up on stairs or other objects in the pool. This can be resolved by adjusting the cleaner's direction or cleaning pattern, installing ladder guards to block the cleaner's path around handrails, or shortening the hose slightly for entry steps and ladders.

Another common problem is that the cleaner stalls or stops working entirely. This can be due to a variety of issues, but the most likely culprit is a dirty or clogged vacuum hose. If the hose is too long or torn, it may be time to replace it. Alternatively, the vacuum hose might have a hole or ill-fitting connection to the return wall fitting that can cause it to stall.

Finally, if the cleaner is not climbing your pool walls or getting stuck on them, it's likely that the brushes and wheels are worn out or not positioned properly. This can be corrected by scrubbing the brushes with a stiff brush or by spraying them down with a pool cleaning solution.

While most of these problems can be easily fixed by yourself, it's still a good idea to bring your cleaner into the store for yearly maintenance to ensure the safety of its motor and brushes. This will not only help prevent costly repairs in the future, but will make sure that your cleaner is able to do its job and keep your pool looking beautiful!
