The Tacony D012-2500 is a 14" metal agitator assembly with 10.3mm non-clutch red bristle brushes. It fits Facet MFC-523, CleanMax 3QD, CleanMax 3T, and CleanMax 3N upright vacuums. The non-clutch design means the agitator runs continuously with the vacuum motor. Note that the NS title field lists this as a Facet brushroll; the brand field reads RICCAR, which appears to be a cataloging error - the part is a Tacony (manufacturer) component that fits Facet and CleanMax branded models.
