A streamer cleaning device includes a plurality of cleaning modules affixed to a main frame in angularly spaced apart orientation. At least one cleaning module includes a drive wheel rotationally coupled to a cleaning element. At least one cleaning module includes a guide mounted thereon. The guide is configured to deflect devices mounted on the streamer out of a path traversed by the cleaning modules. At least one of the cleaning modules comprises a device for conversion of motion of water past the at least one cleaning module into rotational energy to drive the drive wheel thereon.
