ABSTRACT:
A dispenser for dispensing particulate cleaning material onto a floor surface includes a hopper holding the particulate material and a dispensing aperture extending across the hopper through which the material may be dispensed. A separator, which may for example be a wire, is located adjacent the dispensing aperture for separating the particulate cleaning material at the aperture. The wire helps to break up clumps of particulate cleaning material which may form. In use, a plate is vibrated to impart motion to the particulate material in the hopper. The wire can be carried by the plate or by the hopper and is preferably held under tension.
