On the one hand, the fresh water tank 31 supplies fresh water to wet the drum to bring the drum into a cleaning operation. On the other hand, the self-cleaning component 2 extrudes and guides the sewage generated in the cleaning process of the roller 1 to the sewage tank 32, and after the cleaning work is finished, the sewage in the sewage tank 32 is poured out. The drum device 100 of the present invention realizes the self-cleaning of the drum 1 and the collection of the sewage on the drum 1, and has a very simple structure and a small occupied space. The self-walking cleaning device 200 of the present invention can be a floor mopping machine, a floor sweeping machine, a sweeping and mopping integrated machine, etc., and meanwhile, the self-walking cleaning device 200 can be used for cleaning the ground, including tile surfaces, wood floors, etc., as well as the surface waiting for cleaning on a table top.
