While they offer significant benefits over suction or pressure side pool cleaners, robotic models come with a few more moving parts that may break down from time to time. Fortunately, most problems that arise are easy to fix and don’t require the services of a professional.

A common problem that causes robotic cleaners to stop working is a loss of power. Before contacting your local pool professional, first make sure the unit is turned on and connected to a power source. If it is not, try turning it on and plugging in again or resetting it using the user manual's troubleshooting instructions.

The robotic cleaner's internal filter may also become clogged from debris. If this is the case, empty the debris from the internal basket and clean the filters as per your manufacturer's instructions.

Another reason why a robotic cleaner may stop moving is if it gets stuck on something, such as a rock or other item on the bottom of your pool. While this is rare, a good idea is to regularly sweep and vacuum the bottom of your pool to remove any items that could get in the way of the robot's cleaning path.

If the robot is still stuck after this, it might be due to an obstruction in its path, such as a pool grate or wall cover. If this is the case, simply move the item away from the robot's path and it should then be able to complete its cycle.

Lastly, many robotic cleaners have sensors or mapping that help them navigate the pool more efficiently. If yours is not navigating the pool correctly, it may be because of a faulty sensor or other problem that can easily be resolved by consulting your manufacturer's technical support team.

If your robot is not climbing walls as it should, it may be that algae is starting to form on the pool walls and this needs to be treated. It may also be because the cleaner is not able to climb the walls with enough traction or suction and this can be remedied by adjusting the cleaning pattern or cleaner speed as described above.

Some robotic cleaners have the added ability to adhere to and clean the area above the waterline, often known as the tile line. This is an important feature, especially if your property has a lot of trees and leaves can fall in the pool. Make sure your model has this capability before making a purchase.

Overall, robotic pool cleaners are very easy to use and can save you a huge amount of time when it comes to maintaining your swimming pool. However, as with any piece of equipment, it will break down from time to time and can cause frustration. With a little bit of knowledge and the right tools, you should be able to fix your robotic cleaner without having to call in a pool professional. With regular maintenance and care, a quality robotic cleaner can keep your pool looking its best for years to come.
