Robotic cleaners require a bit of maintenance to keep them running smoothly. It’s important to inspect the brushes, tracks and wheels for debris.

It’s also a good idea to check the filter regularly. Large palm fronds and twigs can get stuck in the robot’s motor.

Manufacturers like Zodiac design their robotic cleaners with easy maintenance in mind. This includes making the filters easy to clean and empty.

1. Brushes are not absorbing water

Robotic cleaners are much more durable than a suction cleaner but they are not immune to problems. Most of the time, a simple reboot of the power supply and blue cable will get them going again.

If this does not fix the problem, try to unplug the unit and see if it still turns on without the cable attached. If it does not, the problem may be with the pump or a more serious issue like the motor or control box.

This will probably need to be taken care of by a pool technician. They will need to dislodge any debris stuck in the robot’s wheels or tracks and repair or replace any worn out brushes. Also, make sure the hose is not tangled or putting pressure on the unit and store it in a cool shaded place when not in use.

2. The unit is not moving

Many robot pool cleaner owners find that their equipment stops moving after a short time of use. The unit may get stuck in the corner or stop completely. This can be an issue that requires the assistance of a professional or replacement of the unit.

If the robot is not moving, it may be due to a broken motor or other specific parts. It can also be caused by debris that is lodged in the drive pulleys or brushes. Inspect the pulley teeth and remove any debris to see if this resolves the problem.

It is also important to keep in mind that robotic cleaners need regular maintenance. This includes emptying the bag regularly and cleaning the brushes. Keeping the cable in good condition is also necessary. This means that the cable should not be rolled up too tight or twisted.

3. The unit is climbing the wall

If your robot is climbing the walls when it should not be, this could indicate that algae is building up. It’s important to keep the pool free of algae as it can damage your robot’s brushes and wheels.

Using a brush and cleaning the tracks may help. However, if the problem persists, this is most likely an internal issue and it would require replacement of a part.

A common issue is the cable becoming twisted or damaged. Leaving the unit partially out of water and stretching it out in the sun can help prevent this. It’s also good to roll the cable up in a large loop when removing it. This will prevent it from twisting and kinking. This is especially important if the unit has been left outside all winter.

4. The unit is falling backwards

Robotic cleaners are expensive pieces of equipment that pool owners and technicians rely on to keep their pools clean. However, like any piece of machinery, they can fail when exposed to the elements and misuse. Luckily, most robotic cleaners come with a manual with helpful troubleshooting tips and advice for keeping your pool cleaner working properly.

First, it’s important to verify that the floating power cord is firmly plugged into its power supply transformer, which in turn is plugged into an outlet. It’s also a good idea to inspect the power cord for broken wires, especially near where it connects with the unit. This is where the stress on the cord is the highest.

5. The water is not pouring out of the top of the pump

Robotic cleaners are a great addition to any pool but they do need some upkeep. They can last for up to four or five years with proper care. However, there are many common issues that can arise such as poor suction, getting stuck or climbing the wall, and not moving at all.

The first thing to check is the power cord. It may have become twisted causing it to pull out of the outlet. If this is the case, disconnect it and try again. Also, be sure to roll it up in a large loop to avoid any kinks or imperfections. This can also save you on future repairs. Be sure to regularly empty and clean the filter and cleaning bag. This can help avoid debris buildup and prevent your robot from malfunctioning.
