1. An automatic cleaning device, comprising:
a mobile platform configured to automatically move in a target direction on a surface to be cleaned, the mobile platform having a bottom surface;
a wet-mode cleaning module comprising a cleaning-head, a distance between the cleaning-head and the bottom surface of the mobile platform being adjustable; and
a lifting mechanism configured to drive, via a linear driving mechanism, the cleaning-head to move to thereby adjust the distance between the cleaning-head and the bottom surface of the mobile platform;
wherein when the linear driving mechanism moves in a direction, the distance between the cleaning-head and the bottom surface of the mobile platform is increased; and
when the linear driving mechanism moves in another direction reverse to said direction, the distance between the cleaning-head and the bottom surface of the mobile platform is decreased;
wherein an elastic support structure is arranged between the lifting mechanism and the cleaning-head and configured to urge the cleaning-head to abut against the surface to be cleaned;
wherein the cleaning-head is configured to move relative to the lifting mechanism under a driving force from a gear set to thereby clean the surface to be cleaned; and
wherein a power source, from which the driving force comes, comprises an output shaft, and a line passing through an axis of the output shaft is distant from a region surrounded by a boundary of the cleaning-head.
