Abstract
There is disclosed a variable strength magnetic window cleaning device having a master and slave unit utilizing magnetic force to simultaneously clean both the inside and outside panes of a window. When a user moves the master unit from inside, the slave unit follows the master unit along the outside window, thus cleaning both sides of the window panes simultaneously. A replaceable cleaning surface such as premoistened disposable wipe is secured across the engagement surface area and contacts the window surface to effect the cleaning.
