ABSTRACT A manually operated cleaner such as a carpet sweeper has a roller brush and a rotatable arcute brush body housed, in a body enclosing dust collecting chambers, so as to present parallel portions of their peripheries to a surface to be cleaned through openings in the bottom of the cleaner. A dust removing brush member having dust removing inclined piles tilted in the same direction as inclined piles on the brush body is biased against the brush body. With this arrangement, even if either of the inclined piles wears during use, effective contact between the respective inclined piles can be maintained, ensuring that the removal of fibrous dust and its transfer to the dust collecting chambers continues to take place, whilst even if a large hard dust mass is caught between the brush body and the dust removing brush member during use, this dust mass can be automatically dislodged and transferred to the dust collecting chamber by cooperation between the dust removing brush member which is then forced to rotate in the direction away from the brush body against its bias, and the brush body, which is rotated alternately in opposite directions.
