Tips for keeping pool cleaners going strong

Outside influences

It is also important to check other variables in the pool, rather than just the cleaner. For example, if water is circulating at the surface of the pool, a suction cleaner’s hose may be pushed around, throwing off the cleaner’s ability to randomly cover the entire pool floor. This could also explain why the cleaner routinely gets ‘stuck.’ The circulation pattern can be adjusted by redirecting eyeball returns toward the pool floor if they are not set this way already.

When returns send water straight out into the pool, the result may be surface circulation. A more balanced circulation is better, not only for pool cleaner performance, but also to minimize evaporation (therefore conserving heat and chemicals).

For suction cleaners, it is also important to empty the skimmer and pump strainer baskets, as this is where debris collected by the cleaner accumulates.

To deal with complaints regarding loud booster pumps on pressure cleaners, check the wall fitting to ensure it is properly mounted and connected. The pool’s filtration system should also be inspected. If water seems to be moving as expected, the booster pump may need to be serviced or possibly replaced.

Also keep in mind the impact routine filter maintenance (e.g. backwashing) has on a pool cleaner. Some pressure cleaners, for example, rely on a wall-fitting screen, which should be removed when the pool filter is being cleaned or repaired. If it was not removed, it may be clogged or damaged and need to be replaced. Furthermore, the cleaner’s dedicated line should be flushed out after filter maintenance and prior to reattaching the cleaner.

Environmental factors should also be considered. Sometimes a cleaner or its hoses may suffer damage from ultraviolet (UV) light or chemicals. Whenever possible, make sure cleaners are not left or stored in direct sunlight.

Lastly, cleaners should be removed from the pool when shock treating or adding chemicals, as they are not typically designed to withstand elevated sanitizer or acid levels.

Up to speed

Many cleaners are equipped with self-adjusting regulators to optimize their speed. The ideal setting is not too slow (so it will get the job done as quickly as possible), but also not too fast (which would be equivalent to running with a vacuum cleaner through the house). A pool cleaner that operates too fast may not effectively pick up debris, and will experience accelerated wear and tear. If the pool is clean, it is a strong indication the cleaner is running at an optimal speed.

This is the second of two articles on automatic pool cleaners. The first appeared in Pool & Spa Marketing, January 2011 and covered selection and installation of suction, pressure and robotic cleaners.
