The invention discloses a hand-pressing type two-speed rotating mop which comprises a handle (1), an upper rod (12), a middle rod (4), a first-speed driving mechanism (28), a lower rod (7) and a mop assembly (9). The handle (1) is fixed to the upper rod (12), and the first-speed driving mechanism (28) is connected between the middle rod (4) and the lower rod (7). When the handle (1) is pressed down, the first-speed driving mechanism (28) drives the mop assembly (9) to rotate at first speed. A second-speed driving mechanism (27) is connected between the upper rod (12) and the middle rod (4). When the first-speed driving mechanism (28) and the lower rod (7) are locked, the handle (1), the upper rod (12), the middle rod (4), the first-speed driving mechanism (28) and the lower rod (7) are connected into a whole. When the second-speed driving mechanism (27) is pressed down, the mop assembly (9) is driven to rotate at second speed. By the adoption of the structure, the hand-pressing type two-speed rotating mop has the advantages of being simple and reasonable in structure, light and convenient to operate and use, good in cleaning and dehydrating effect, low in production cost and long in service life, rotating at different speeds during cleaning and dehydrating, and the like.
