Abstract: A panel cleaning roller assembly capable of comprehensively wiping a panel has an axle serving as a rotating body, and a roller serving as a wiping body. The roller is wound around and rotated synchronously with the axle. The roller has a wiping surface having longitudinally curved grooves, transversally curved grooves and wiping grains formed between the longitudinally and transversally curved grooves. The wiping grains are arranged in a curved matrix. Thus, the axle may be utilized to rotate the roller relatively to the panel to perform the rotating wiping and absorb the foreign object or debris to the longitudinally and transversally curved grooves of the roller, thereby preventing the surface of the panel from being scratched. Thus, the comprehensive wiping can be performed without forming any gap, thereby significantly enhancing the cleaning efficiency and quality and effectively enhancing the utility.
