A rotary disc floor apparatus (A) is disclosed for cleaning surfaces of floors or the like. The apparatus (A) includes a rotary block (30) having bristles (40) for scrubbing a floor surface with cleaning solution. The apparatus (A) further includes a wiper and vacuum nozzle assembly (20) having a ring (88) with squeegees (128) and nozzles (154) forming vacuum nozzle openings (163). The squeegees (128) and nozzles (154) include respective wiping portions (148, 166) having portions disposed outwardly of and located at a greater distance from the axis (B) than the nozzle openings (163). The squeegees (128) and nozzles (154) are readily removable and readily attachable to the ring (88) via shafts (140, 142, 158, 160). The apparatus (A) further includes flat springs (186) for biasing the ring (88) downward toward the floor surface and relative to the rotary block (30).
