The invention relates to a jet self-cleaning screen filter. The filter consists of a jet element, a screen filtering component and a dirt sucking component, wherein two water inlets of the filtering component are formed on the two sides of a hollow thin cylinder of the dirt sucking component and are connected with two output ends of the jet element respectively; and the water outlet of the filtering component is connected with a water delivery pipeline. Differential pressure formed by the blockage of a filter screen drives the wall attachment and reversing of jet to push the dirt sucking component to do cyclic reciprocating motion, so that obstructions aggregated on the filter screen are sucked and discharged, and the self-cleaning process of the filter screen is realized; the dirt sucking component is automatically operated and reversed by the jet; a reversing mechanism is durable and reliable; and the filter has a simple structure, is convenient to install and use, can automaticallyclean the filter screen in a working state, can continuously work and is suitable for filtering micro-irrigation, spray irrigation, low-pressure pipeline irrigation water and industrial circulating and cooling water.
