Abstract
The present disclosure discloses a window cleaning device. The device is constituted by two cleaning units, each is configured to be attached to a different side of the window due to attraction force of the other cleaning unit. The attraction force is applied by magnetic members that are embedded in each of the cleaning units and each of them is configured to be magnetically coupled with at least one magnetic member of the other unit. Once the cleaning units are attached to the window, the window is engaged either by integral wipers of the cleaning unit and/or cleaning cloths attachable to the cleaning units to perform the cleaning process by the device. The cleaning units are each a single-piece molded article made of rubber, silicone rubber, elastomeric material or a thermosetting material, namely a relatively soft material, softer than the plastic material forming the known window cleaning devices.
