This application relates to the field of tarpaulin cleaning technology, disclosing a high-strength self-cleaning sunshade tarpaulin, including a tarpaulin, a cylinder, blades, a hollow shaft, a cross-shaped spray frame, spray pipes, first nozzles, cross-shaped pipes, and valves. In use, the water supply equipment is controlled to operate, and water is delivered through multiple hoses into the interior of multiple cross-shaped pipes, ultimately being sprayed out by multiple spray pipes and multiple first nozzles. When water is sprayed from the multiple first nozzles, fine water streams are evenly sprayed onto the tarpaulin surface, carrying dust from the sides of the tarpaulin to the ground. When water is sprayed from the multiple spray pipes, multiple high-pressure water jets are directed at multiple blades. Then, under the push of the reaction force, the multiple cross-shaped spray frame rotates. This ultimately drives the multiple first nozzles to rotate, thereby increasing the spray range and improving the dust removal effect. Because the multiple nozzles are evenly distributed on the sides of the tarpaulin, it is convenient to clean the entire side when the tarpaulin is unfolded.
