FIELD: equipment for cleaning apparatuses such as robot-vacuum cleaner.

SUBSTANCE: brush has rotating spindle placed in the vicinity of case lower part, brush hub attached to rotating spindle, and brush bristles secured on outer circumferential surface of brush hub and adapted for sweeping dust and contaminant from floor. Brush bristles are arranged in first row divided into first part of bristles which are out of contact with floor, and second part of bristles, which come into contact with floor, said second row being arranged sequentially with respect to first row and being divided into first part of bristles coming into contact with floor and facing toward first part of bristles of first row, and second part of bristles, which are not brought into contact with floor and are facing toward second part of bristles of first row. Brush is used in cleaning apparatus such as robot-vacuum cleaner having suction opening provided in central part of case lower surface and adapted for performing cleaning operations upon automatic displacement and automatic charging of accumulator battery.

EFFECT: reduced loading during rotation and increased cleaning efficiency owing to dividing brush bristles into part contacting with floor and part out of contact with floor to thereby reduce area of brush surface contacting with floor.
