A shaving apparatus, comprising: a) a body comprising: i) a bottom surface, a top surface, a front portion, a back portion and a central lumen forming a lumen opening at the back portion of the apparatus, the central lumen having a bearing surface; ii) one or more rolling elements rotatingly attached to the bottom surface, near the front portion of the apparatus; b) a shaving head assembly rotatably attachable within the central lumen of the body, the shaving head assembly comprising: i) one or more shaving blades mounted within a blade cartridge, the one or more shaving blades having a major orientation axis; ii) a blade cartridge attachment arm for attachment of the blade cartridge to a mounting shaft having a bearing surface; wherein the shaving head assembly, or a subunit thereof, rotates about an axis of rotation defined by the major axis of the mounting shaft; characterised in that the shaving head assembly is removably retained within the central lumen through the cooperation of one or more engagement elements of the mounting shaft with retaining elements located within the central lumen; and wherein the removal of the shaving head assembly is facilitated through a mechanical release mechanism which includes an actuator having a proximal end, wherein when a force is applied at the proximal end of the actuator, the actuator is displaced to interrupt the cooperative engagement between the one or more engagement elements of the mounting shaft with the retaining elements located within the central lumen. a) a body comprising: i) a bottom surface, a top surface, a front portion, a back portion and a central lumen forming a lumen opening at the back portion of the apparatus, the central lumen having a bearing surface;
