Not really needed, it just uses up electricity as Carl said and can push the fine collected particles in the sand filter out into the pool again.
It's not ironic, most filtration works better when you don't apply a pressure of 14PSI to force the dirt through it.
It's not an RO membrane filter which is where pressure is needed.
