Abstract
A cleaning device for cleaning a marine element towed in water and related methods are provided. The cleaning device includes a body configured to enclose the marine element; at least one wing attached to the body and configured to impart translational and rotational motion to the body when interacting with the water; a switching and locking mechanism configured to change an orientation of the at least one wing between a first orientation and a second orientation when contacting a stopper and also to lock the selected orientation; rotating means attached to an internal surface of the body and configured to contact the marine element, the rotating means having axles that make a fix angle with a longitudinal axis of the body; and a cleaning tool attached to the body and configured to clean the marine element.
