    Abstract: Embodiments of the present disclosure relate to a lifting apparatus for a cleaning assembly, a cleaning assembly, and a cleaner. A lifting apparatus for a cleaning assembly is adapted to be mounted in the cleaning assembly. The lifting apparatus includes: a motor including an output shaft; a roller coupled to the output shaft and configured, with rotation of the output shaft (310), to rotate about an axis (A) of the output shaft (310) along a first rotation direction (R1) or second rotation direction (R2), the first rotation direction (R1) being opposite to the second rotation direction (R2). The lifting apparatus further includes a boss. The boss is fixedly disposed on an end on one side adjacent to the roller and away from the output shaft, and configured to lift the roller when the roller rotates along the first rotation direction. In this way, there is no need for providing a drive apparatus of a lifting mechanism. In addition, the lifting mechanism is advantageous in simplicity, fewer parts, small structural space of the sweeper, high reliability, and low cost.
