ABSTRACT:
A rug scrubbing machine for cleaning variable depth sculptured rugs and the like which features an arrangement permitting selective tilting of the frame carrying the scrubbing brushes. Variation in the tilting angle is achieved by pivotally mounting the front wheel, with means for selectively controlling the orientation of the bracket carrying the front wheel. Also provided is "free floating" axial movement of the brushes so as to accommodate varying textures and thicknesses of the rugs to be cleaned, thereby foreclosing any need to adjust the device manually as rugs of different characteristics are encountered except insofar as different tilt angles are called for.
