An automatic screen cleaning apparatus that cleans itself by flushing the attached debris back through the inlet screen 25 as part of its operating cycle. It comprises a body having an upper tank 20 for receiving a liquid, the upper tank having a fluid inlet 24 comprising a perforated screen; a lower tank 22 in fluid communication with the upper tank; a valve 26 located between the upper and lower tank; a float member 32 located in the upper tank; a screen seal member 30 adapted to seal the fluid inlet; and a resiliently biased actuator 33 in engagement with the float, the valve and the screen seal member and moveable between a first configuration in which the valve is closed and the fluid inlet is open and a second configuration in which the valve is open and the fluid inlet is sealed by the screen seal member, the movement between the two configurations being in dependence upon the position of the float within the upper tank. Later embodiments relate to a method of cleaning a screen using the apparatus and a sewage pumping station comprising the apparatus.
