Abstract
A domestic appliance includes a head divided into a first rotatable member and a second rotatable member, and a drive mechanism for rotating the head about a first axis while simultaneously rotating the first rotatable member about a second axis and the second rotatable member about a third axis. Each of the second axis and the third axis is angled to and preferably intersects the first axis. When viewed in a direction extending along the second axis towards the first axis, the drive mechanism rotates the first rotatable member about the second axis in a first angular direction and the second rotatable member about the third axis in a second angular direction opposite to the first angular direction.
