If your cleaner isn't cleaning the bottom of your pool or it's taking a long time to finish, it may be due to low suction. Make sure that your filters and auto cleaner's suction line are clear of debris and that there are no blockages. Check for air leaks in the hose while it's running. Close any other lines such as the main drain to improve the suction of the hose your cleaner is connected to.
If you've done all of the above and your cleaner still isn't performing at its best, there are several more things to try. First, verify that the hose is the correct length for your pool size. Excess hose can cause the cleaner to twist and tangle during operation. If you find that the hose is too short or has been torn up, replace it with a longer one. Keeping the hose free from obstructions is a major factor in how well a robot cleaner performs.
It is important to remember that both pressure-side and robotic cleaners rely on your pool's filtration system (though robotic cleaners operate independently of it). Keeping the entire filtration system clean helps your cleaner by providing a constant supply of water. The simplest way to do this is to regularly inspect your filter, baskets, pumps, and strainers for any debris that can interfere with the operation of these systems. It is also a good idea to have your system serviced by professionals at least once a year.
Another common issue that affects both types of cleaners is when the vacuum bag or skimmer container are full, preventing the cleaner from powering around the pool. Be sure to empty the skimmer and leaf bags when they are full, and that your vacuum bag is emptied before operating your cleaner again.
Some robotic cleaners use tracks or wheels to traverse your pool's walls and floors, rather than using the drive belt that connects to a motor. Depending on the type of pool you have, this feature can be a huge benefit. However, it is important to understand that these systems are prone to wear and tear, especially over time. Look for signs such as leaking propellers, a clogged wheel or track, and other obvious signs that your pool cleaner is ready to be replaced.
Purchasing a new pool cleaner doesn't have to be an expensive or intimidating task. If you keep your eye out for warning signs and act quickly when necessary, you can get the most out of your automatic cleaner without breaking the bank. The most important thing is to understand your needs and preferences for a new machine, so that you can decide which features are right for your home swimming pool. With a bit of research, finding the perfect automated pool cleaner for your pool will be easy! Good luck and happy cleaning!
