A surface treating appliance includes a main body and a head rotatably connected to the main body about an axis, the main body and the head being provided with first and second electrical connectors, respectively. The first and second electrical connectors can be connected to provide an electrical connection between the main body and the head. One of the first and second electrical connectors is slideable within a channel. By providing an electrical connector within a channel, complicated and potentially unreliable arrangements such as slip-rings can be avoided while still providing an electrical connection between the head and the main body.
