摘要： A floor surface cleaning machine includes a suction mechanism disposed at a bottom side of a machine frame for suction of dust and dirt on the floor surface, a brush mechanism disposed at the bottom side of the machine frame rearwardly of the suction mechanism for brushing the floor surface with cleaning liquid, and a squeegee unit disposed at the bottom side of the machine frame rearwardly of the brush mechanism for gathering dirty liquid. Before brushing the floor surface, fibers may be removed from the floor surface together with the dust and dirt for preventing the fibers from being tangled up with bristles of the brush mechanism.
