The invention relates to a device for doing mopping work on the household ground and belongs to the field of environmental engineering. In order to enable the household ground to be mopped and rapidlyair-dried, the invention discloses a household mopping device. According to the technical scheme, the device is placed on the ground, and a pressure valve on a water pipe is opened so as to enable aspray head to spray water, the whole device is driven to drive a mop to do the mopping work, then a fan is started, under the joint action of the fan and a sponge piece, the mopped ground is rapidly dried, and then the whole mopping work is completed. The household mopping device disclosed by the invention has the following advantages that (1) a crawler-type walking mechanism is used as a whole device driving mechanism, so that the whole device moves more stably, and the obstacle crossing capacity is relatively strong; (2) the fan and the sponge piece are installed behind the shell, so that the drying speed of the mopped ground is greatly improved; and (3) the structure is simple, convenience is brought to disassembling, and inspection and maintenance are facilitated.
