Einstein said that doing the same thing over and over again, and expecting a different result, is  the definition of insanity. So, when your pool is stuck in a pattern, and it expects a clean pool, is it insane?

Well, no. But it’s certainly not functioning efficiently.

Your solution is to ensure that the water-flow from all return inlets is directed downward and toward each other, or downward and toward the centre of the pool. This will help prevent water-flow from affecting the natural movement of the cleaner’s hose.

You should also take the cleaner out of the pool and lay the hose in a straight line in the sun to relax its memory. Leave it there for the best part of a day. When you place the cleaner back in the pool, check that you have the proper hose length. If the pool cleaner is still patterning and not covering the pool properly, then you might need to add one or two extra hose lengths.

Also, it’s important to adjust that hose weight so it’s sitting at the end of the first length of hose, the leader hose.
