The invention discloses a novel cleaning device of an automobile accessory. The device comprises a base, a splash-proof cover and a bin door, wherein the splash-proof cover is embedded in the upper portion of the base, and the side edge of the splash-proof cover is rotationally connected with the bin door through a hinge; the interior of the base is divided into a waste liquid collecting bin and an equipment bin through a partition plate from top to bottom. According to the device, a spraying frame movably connected by a bearing is vertically arranged on the upper portion of the base, and a second incomplete gear sleeves the bottom of the spraying frame, then a motor drives a first incomplete gear to be in meshed transmission with the second incomplete gear, and then three vertical pipes are vertically arranged on the upper portion of the spraying frame at equal intervals, and the vertical pipes are connected with the inner top face of the base through springs; and the first incompletegear is driven by the motor to be meshed with the second incomplete gear to drive the spraying frame to rotate, then an initial state is restored through the springs, so that periodic vibration scouring of the spraying frame is realized, and the washing efficiency of the spraying frame is improved.
