Automatic pool cleaners help keep the bottom of a swimming pool clean, but they need regular repair and cleaning to function correctly. The good news is that many of the problems associated with these machines are relatively minor and can be fixed easily by a home owner or technician. Those who regularly inspect their cleaners can often catch issues before they become more serious and avoid unnecessary replacements, says Kreepy Krauly's Shulman.
For example, if a suction-side cleaner isn't climbing walls or the floor of a pool, check the wheels and tires. They may be worn out, which can cause the machine to scrape on the surface of the pool. This can speed up the wear of the skirts and other underneath parts. Rief suggests that homeowners and technicians periodically take a cleaner out of the water, turn it upside down, and examine the wheels and tires to make sure they're not worn out or cracked.
Another common issue is a malfunctioning microchip that controls the robot's drive motors. This problem can occur when the machine becomes confused about which direction to go after it climbs a wall, and it can also happen when the machine gets caught up in debris. If this happens, pull the cleaner out of the water and turn it off. Then, remove the filter canister, and test the machine to see if it functions properly without it.
Other issues can include a clogged suction vent, dirty brushes or improper floatation. Often these are easy to fix, but it's important to know how to do so. When a vacuum has a clogged skimmer basket, for instance, it's usually because sand is getting trapped inside. If the filter is clogged with dirt, it's likely because the vacuum needs to be backwashed.
A hose that is too long or has a tear or hole can result in air bubbles entering the system, which causes the cleaner to not operate properly. Examine the hose to ensure it is not too long, and try to get rid of any blockages by using water pressure on the hose to dislodge them.
For robotic cleaners, it's important to make sure the brushes are cleaned and that the floatation settings are correct. If the unit isn't able to climb walls or pick up debris, this could mean that the PVA brushes are not working properly or the vacuum vents are blocked with sand or leaves. It's possible that the filters need to be cleaned as well, and a quick inspection of the machine should reveal the culprit. If the machine is still not working after examining these basic components, it's time to call a professional.
