<p>A dispenser (50) for dispensing particulate cleaning material onto a floor surface comprises a hopper (52) for holding the particulate material. A part of the hopper (70, 71) is movable with respect to the hopper (52) to define a dispensing aperture (75) and to impart movement to particulate material in the hopper towards the dispensing aperture (75). The dispenser (50) is attachable to a floor cleaning apparatus (10). Biasing means (56) bias the movable part (70, 71) into a position which closes the aperture (75) when the dispenser (50) is removed from the floor cleaning apparatus. Thus, the dispenser (50) is self-closing.</p> |
