In some embodiments, the driving assembly 32 includes two driving rollers 33 axially parallel and spaced apart from each other, and the cleaning member 34 is wound around the two driving rollers 33. In this way, the cleaning member 34 is sleeved outside the two driving rollers 33 to form the cleaning mechanism 30, and when any one of the driving rollers 33 is driven by the driving member to rotate, the cleaning member 34 and the other driving roller 33 can be driven to move, so that the cleaning member 34 can rotate circularly. Optionally, the cleaning member 34 is a cleaning cloth. In addition, the wiper 70 is located between the two drive rollers 33, and is provided to extend in a direction parallel to the axial direction of the drive rollers 33. Thus, the space between the two driving rollers 33 is used for accommodating the water scraping piece 70, so that the whole cleaning device 100 is more compact in structure and more miniaturized in volume. In addition, the cleaning member 34 is wound around the two driving rollers 33, the cleaning member 34 and the wiper member 70 extend in a direction parallel to the axial direction of the driving rollers 33, the wiper member 70 extends across the entire cleaning member 34 in the direction parallel to the axial direction of the roll brush, and the cleaning member 34 can completely pass through the wiper member 70 when rotating, so as to ensure the water squeezing effect.
