The invention relates to a jet cleaning device, and belongs to the field of industrial cleaning. The jet cleaning device comprises a tank body, an acceleration jet assembly and a limiting assembly; the tank body is used for containing cleaning sand and cleaning liquid, a mounting hole is formed in the top, the acceleration jet assembly comprises an air inlet nozzle and a jet pipeline, the air inlet nozzle is of a hollow frustum structure, and is formed in the bottom of the tank body, the jet pipeline comprises a main pipeline and an outgoing pipeline, the main pipeline is a straight pipe, andis arranged in the tank body, the lower end is matched with the air inlet nozzle, the upper end extends out of the tank body through the mounting hole, the outgoing pipeline is connected with the upper end of the main pipeline, the limiting assembly is fixed to the outer portion of the tank body and is used for limiting the elevating height of the main pipeline, and when the device does not work,the main pipeline is tightly matched with the air inlet nozzle; when the device works, the outgoing pipeline is closed, the air is inflated to the main pipeline through the air inlet nozzle, and the main pipeline is elevated along the mounting hole, and is separated from the air inlet nozzle. A high-pressure water source is not needed, and the cleaning energy consumption is greatly reduced.
