Pool cleaners should be left in the pool so that they can work every time the system comes on. If you do take them out, they must be stord out of the Sun and NEVER coil the hoses. If you do they will be ruined after a short while. I'm sure that someone will reply that they have always coiled the hoses with no problems (there's always an exception) but nearly 20 years in the business say otherwise.
