ABSTRACT:
A glass cleaning device employs an inner component having a body with an associated first cleaning element and a second movable portion positionable from a first to second position, the second portion associated with a second cleaning element. A support magnet is carried within the body and at least one magnetic element is carried in the second movable portion. An outer component provides a handle for manipulation by a user with a first magnetic element carried within the handle for operable engagement of the support magnetic in the inner component to draw the body into contact with an inner surface of an aquarium wall to be cleaned. A selection magnet carried within the handle allows engagement with at least one magnetic element in the movable portion. Positioning of the selection magnet adjacent the magnetic element actuates the movable portion for operable engagement of the second cleaning element on the inner surface of the aquarium wall.
