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.
