Abstract: There are disclosed, in combination, a resiliently compressive, porous rotary buffing pad and a pad holder adapted for use in floor polishing machines. The pad holder is of one piece construction and is formed about its perimeter and toward its center with areas which compress the pad to increase friction with a floor during polishing while reducing overall energy requirements. Immediately adjacent to each such compression area the pad holder defines an area which does not contact the pad and which promotes filtering and storage of particulates. This combination, with adjacent integrally connected compression, non-compression areas promotes efficient polishing with reduced energy resulting from the use of discreet compression areas; and dust or particulate absorption and storage within the non-compression areas.
