ABSTRACT:
A dispenser for dispensing particulate cleaning material onto a floor surface includes a hopper holding the particulate material and having a dispensing aperture defined by a part that is movable with respect to the hopper itself. This moving part also imparts movement toward the dispensing aperture of particulate cleaning material in the hopper. The dispenser may be attached to a floor cleaning apparatus and includes a biasing device that that biases the movable part into a position which closes the dispensing aperture when the dispenser is removed from the floor cleaning apparatus.
