  • Publication number: 20090133209
    Abstract: A surface treating appliance includes a main body, a head and a connector. The connector is adapted and arranged to connect the head to the main body while allowing relative rotation therebetween. The connector includes a connecting member which is removable from the remainder of the connector to allow the head to be released from the main body. At least a part of the connecting member forms a part of the external surface of the surface treating appliance. By providing such an arrangement, the connecting member is immediately visible to the user and can be accessed easily. Further, only the connecting member needs to be removed in order to release the head from the main body, making removal of the head a simple and straightforward process.
