A window cleaner that includes a handle, and base and a pivot joint. The handle has a proximal end and a distal end with the distal end being a forked yoke member. The base has a top surface and a bottom surface with a housing and a wiping blade located on the top surface. The pivot joint has a center with four legs extending outwardly from the center. Two of the legs form a first pin and two of the legs form a second pin. The first pin interfaces with the yoke member and the second pin interfaces with the housing. This pivot joint configuration allows the handle to have a range of 360 degree motion with respect to the base and vice versa.
