ABSTRACT:
An apparatus for attachment to a commercially available cleaning wand for maneuvering the wand inside a storage tank. Two arms each have an end pivotally connected to a handle and another end pivotally connected to the wand to form a four bar linkage. A gimbal arrangement is supported above a base, which is placed over an opening in the tank, and one of the arms is coupled to the gimbal arrangement to allow movement about three mutually perpendicular axes for directing the wand to various orientations within the tank.
