Abstract: The present disclosure discloses a window cleaning device for cleaning a window. 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, from the other side of the window. 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.

Abstract: Provided is a mopping unit including: a mop base, a head unit and a coupling element; wherein the coupling element having two parallel elongated reinforcing end segments integral with and flanking a central, coupling segment; the base, being a single-piece molded article having a bottom face and a top face; two elongated bores are formed in elongated abutments on the top face, each accommodating one of the two reinforcing end segments; the base being configured for attaching a mopping substrate on the bottom face; and wherein the head unit being pivotally coupled to said central segment to permit it to pivot about a first axis essentially parallel to said central segment and including a receptacle for an end of a mopping handle.
