The CentraMop Attachment uses the power of your central vacuum coupled with a removable and machine washable cleaning cloth to provide you with easy, powerful and convenient cleaning. The CentraMop captures and locks dirt, hair, dust, crumbs and common household allergens into the thick, textured cloth, while larger objects are trapped by two rows of brushes and swept away. Works with wet or dry cloths. Fits most standard 1-1/4″ central vacuum wands.
