Depends on your pool and your pools needs. First function of a pool pump is to create/distribute the chlorine in the pool. Your signature does not show a SWCG or tablet chlorinator so we can assume you add liquid chlorine to the pool each day. The pump should run for at least an hour after you add the chlorine.
The next reason to run the pool pump is to skim the surface. As you have a VS pump, you should test what rpm of the pump provides the best skimming of your pool surface. Once you have that, you then run the pump long enough each day to skim the surface. You do show a pool cleaner but not sure if that is suction or pressure side. That will change the rpm needed for the time you run the vac.
