Swimming pool pumps can leak at the inlet or the outlet as well as at the shaft seal. The inlet being the suction pipe fitting and the outlet being the return pipe leaving the top of the pump  and feeding into the filter. The shaft seal is the mechanical seal which makes sure the shaft is sealed where it enters the body of the pump. When this seal gets worn the pump will suck air whilst it's running. This will seem like a suction problem but will not be found on the suction line. The pool cleaner will stop running if this leak is bad enough but a shaft seal is easily replaceable unless the pump came in contact with salt for an extended period of time.
