A rolling brush assembly includes a rolling brush having a rolling brush roller, at least two brush bars, and a protruding strip extending lengthwise along an axis. Each brush bar extends lengthwise in a longitudinal direction of the rolling brush roller. The brush bars are arranged at intervals along a circumferential direction of the rolling brush roller with the protruding strip located between adjacent two brush bars. The at least two brush bars are fixed on the rolling brush roller in one of a flocking or an inserting manner. An engagement portion is formed between the brush bars and the rolling brush roller. A distance from an outer end of the engagement portion to the axis is less than a distance from an outer end of the protruding strip to the axis.

A floor cleaning machine having a cleaning element arrangement with inner and outer cleaning elements that include inner and outer cleaning bodies, respectively, that extend jointly in the cleaning body plane and have first and second receiving openings, respectively. The inner and outer cleaning elements extend from the inner and outer cleaning bodies, respectively, away from the cleaning body plane to one side thereof. The inner cleaning body is arranged in the second receiving opening. The output shaft extends with an output shaft section into both the first and second receiving openings. First and second eccentric elements are attached to the output shaft section and to the inner and outer cleaning bodies, respectively, so that when the output shaft is rotated, the inner and outer cleaning bodies perform eccentric movements that are phase-shifted with respect to one another.
