A portable mop comprises a mop rod (1). The mop rod (1) is provided with a steering mechanism (5). The steering mechanism (5) comprises a sleeve nut (6), a locking thread sleeve (7) and a hinged ladder rotating shaft (8). A hinge plane (10) is arranged at the upper end of the hinged ladder rotating shaft (8); and the hinge plane (10) of the hinged ladder rotating shaft (8) is inserted with a hinge connecting lug (11) at the lower end of the mop rod (1) through a pin shaft to constitute a hinge mechanism (29) of the mop rod (1). In a mop bucket used with the portably mop, an integrated squeezing and brushing device is formed by the connection of the squeezing roller pair and the brush body by virtue of a combined support; the combined support comprises a left and a right side baffles; and the brush body is fixedly connected with the squeezing roller pair through connecting screw rods to form a whole. The portable mop achieves the purpose of wiping the hidden corners by turning, and mop heads with narrow and wide working surfaces can also be rapidly replaced. The squeezing rollers and the brush body can be rearranged; the working space of the mop bucket can be increased for the convenience of washing; and meanwhile, the functions of wiping while adding water and shoveling hard lumps can also be achieved.
