A device for cleaning windows, more particularly the interior surface of aquarium windows, comprises a wiper (1) having a wipe side with thereon a wiping layer (4), and an actuator (2), which when in use are each positioned on either side of the window and f ace each other. The wiper and the actuator attract each other by means of a magnetic force, while the wiper positioned on the other side of the window with the wipe side against the window is moved along when the actuator is displaced. The wiper is a body having a mass density that is greater than that of the liquid in which the wiper is used. The wiper has a moment of inertia at which at least a single tilting movement is carried out when said attractive force is terminated and a rotation is followed and an angle is formed with the horizontal direction while the wiper is disposed on a side that is substantially turned away from a plane in the horizontal direction. This achieves that during sinking the movement is slowed down and that the wipe side does not end up on the bottum and become soiled. |
