Abstract: A cleaning device includes a main body, a driving assembly, and a cleaning assembly. The driving assembly includes a driving device, at least one transmission member and a movable bracket. The driving device is arranged on the main body, and has a driving shaft extending toward the bottom of the main body. The movable bracket can be movably connected to the bottom of the main body, and is spaced from the driving shaft. The movement direction of the movable bracket is substantially perpendicular to the extension direction of the driving shaft. The at least one transmission member is connected between the movable bracket and the driving shaft. The driving shaft of the driving device drives the movable bracket to reciprocate back and forth through the at least one transmission member. The cleaning assembly is detachably connected to the movable bracket.

Abstract: The cleaning device includes a main body and at least one drive wheel. The at least one drive wheel is arranged on the main body. The main body can walk on the surface to be cleaned by means of the at least one drive wheel. The cleaning device further includes a driving mechanism, a movable bracket, and a cleaning assembly. The driving mechanism is arranged on the main body, the movable bracket is movably connected to the bottom of the main body, and is connected to the driving mechanism. The movable bracket reciprocates along the direction parallel to the surface to be cleaned under the driving action of the driving mechanism. The cleaning assembly is detachably connected to the movable bracket.
