Provided are a lifting apparatus and a cleaning device. The lifting apparatus comprises a lifting assembly (110), a protection assembly (120) and a drive assembly (130). In the process of using the lifting apparatus to drive an object to ascend and descend, the output end of the drive assembly (130) outputs a driving force by means of the protection assembly (120), so as to drive the object to ascend or descend by means of the lifting assembly (110). After the object ascends or descends into place, when the object is displaced by an external force, the object applies a force to the protection assembly (120) by means of the lifting assembly (110), and the protection assembly (120) is separated from the drive assembly (130). In this situation, a hard mechanical contact is not present between the drive assembly and the lifting assembly, the structure of the lifting assembly and the drive assembly is not damaged, the service life of the lifting apparatus can be prolonged, and the control precision of lifting the object by the lifting apparatus can be improved.
