The head portion includes a spring assembly, having two spring sections, the spring assembly having a node point between the two ends and a nodal mount member at the node point which is connected to a cover member of the head portion. A driving assembly is arranged to drive the first spring section, the second section rotating in an opposing direction from the first spring section, the second spring section having a drive shaft extending therefrom, upon a free end of which a brushhead is mounted. When the head portion is removed from the handle, the spring assembly is removed therewith.
