Disclosed is a water turbine or water pump with a rotor (1) and a guide whee l (2). The inflow edges (13) and outflow edges (14) of at least the rotor blad es (6) form a bend (15) protruding against the direction of flow (15). A flowin g force is thereby exerted on impurities deposited on the inflow edges (13) causing a self-cleaning effect. However, the construction enabling adjustability of the rotor blades remains substantially unchanged.
