A cleaning apparatus comprises: a main rod, a fastening device, a cleaning head and a wringing device. Two holding plates are mounted on the fastening device via two movable connecting pieces. The cleaning head has two hold plates and a sweeping element, attached to lower sides of the held plates. The held plates carry L-shaped fastening devices which respectively engage with openings in the holding plates and point outward, thereby being stably held in place due to elasticity of the sweeping element. Mounting and removing of the cleaning head is performed in a single step by longitudinal compressing of the sweeping element and allowing the fastening elements to engage with and disengage from the openings.
