A carpet brush attachment for a floor treating machine including a circular machine supporting plate having a circular hub extending axially therefrom. The circular plate has formed adjacent the outer edge thereof and spaced from the hub an annular flange acting as a stop for a ring brush. The ring brush is formed with spaced holes through which extensions formed on the plate freely extend which rotate the brush and allow the brush to move vertically upon the extensions and thereby rest floatingly on a carpeted surface to be cleaned with the plate on the surface and supporting the machine.
