The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the device comprises a housing (2) for receiving a cartridge (200). The cartridge (200) has a plurality X of chambers (210), each accommodating a detergent composition. The device further includes a directing means (3, 34) to direct wash liquor selectively into a chamber (210) of the cartridge (200) to contact the detergent composition within it, and an outlet to allow the detergent loaded wash liquor to exit the device. The device also includes indexing means (100) for causing automatic movement of the cartridge (200) relative to the directing means (3, 34) during and subsequent to a wash cycle so as to cause a neighbouring chamber (210) to be exposed prior to a next washing cycle.
