A spring-biased pivoting squeegee 10 provides a head 12 pivotally attached to a handle 16. The head 12 is movable between a rest position, in which the head 12 is angularly displaced from the handle 16, and a biased position in which the head 12, handle 16, and wiping blade 14 are in linear relation. In the biased position, the wiping blade is maintained at an optimum angle for cleaning a glass surface even with the handle 16 held generally perpendicular to the glass. A spring 60 is fully contained in the head 12 and biases the head toward the rest position. A tension adjustment knob 80 in the head 12 permits adjustment of the spring 60 to a tension level according to the ergonomic requirements of a user.
