The invention discloses a washing machine adopting high-pressure water. The washing machine comprises a rack as well as a washing device and a part rotating device which are arranged on the rack; thewashing device comprises a rotating spray head, a first motor for driving the rotating spray head to rotate and a water pipe connected with the back end of the rotating spray head to provide a high-pressure water source; a gear is arranged at the back of the rotating spray head; a first bearing is arranged in the position, corresponding to the rotating spray head, of the rack; the first motor drives the gear through a chain to enable the rotating spray head to rotate; the part rotating device comprises a bearing platform and a second motor for driving the bearing platform to rotate; clamping devices for clamping parts are arranged on the bearing platform; the bearing platform rotates relative to the rack by the aid of a second bearing; and the rotating direction of the rotating spray headis opposite to the rotating direction of the bearing platform, so that the contact force between the high-pressure water and the surfaces of the to-be-washed parts is increased, and the washing effectis enhanced. The washing machine is simple in structure, good in washing effect and capable of saving the water source.
