A hand-operated cleaning brush having means for automatically turning the brush body in a one-touch operation is provided. The cleaning brush comprises a handle, a brush holder having a hollow boss which is rotatably, upwardly and downwardly mounted on a shaft projecting downwardly from the brush holder into the hollow boss, a spring means arranged within the hollow boss to urge the brush body toward the brush holder, an actuating lever mounted on the brush holder and forked at its front end into two arms which cooperate with the boss such that when the actuating lever is operated the boss together with the brush body is pressed down against the force of the spring thereby releasing the boss from its locking position and causing it to rotate 180 DEG and to return to the position wherein the boss with the brush body is urged toward the brush holder to lock the brush body in place.
