Abstract: A mop self-lifting cleaning tool includes a mop and a mop bucket. The mop head of the mop includes a fixed plate and a lifting plate. The fixed plate is connected to the mop rod. The lifting plate is connected to the fixed plate. A gap is provided between the lifting plate and the fixed plate, where the gap is increasingly smaller from the center of the lifting plate to the periphery of the lifting plate. A drive member is located in the gap. When the drive member is located at an end with a larger space of the gap, the lifting plate is located at a low position; and when the mop head rotates, the drive member is configured to move toward the periphery under an action of a centrifugal force and drive the gap to increase so as to elevate the lifting plate to a high position.
