ABSTRACT:
A device for cleaning shoe soles, which can be stepped over, includes a grid with cylindrical rings having engaged surfaces and forming circular passages through the grid. A frame encloses these rings and has vertical pins extending through the axes of the rings. The cleaning brushes are plate-like and ring shaped and are rotatable upon these pins. The brushes extend into the circular passages of the grid. The pins also carry upper round plates, whereby the plates and the rings constitute edge supports for the brushes.
