A device and method for coupling a cleaning implement to a floor cleaning machine. The device includes a plate that has a first edge, a second edge, and a main body portion extending between the first edge and the second edge. The device also includes projections and recesses positioned to releasably engage with each other to releasably couple the plate with the cleaning implement, and a channel that is coupled to one of the first edge and the second edge of the plate to receive an edge of the cleaning implement. The channel has a first end for initially receiving the edge of the cleaning implement during insertion, and a second end positioned opposite the first end. A retainer is in communication with the channel to selectively prevent the cleaning implement from disengaging relative to the coupling device.
