Abstract
A cleaning roller for a suction head has a substantially cylindrical base body with a cylindrical mantle surface. The base body is driven in rotation about an axis of rotation. Support members are connected to the base body and project radially past the cylindrical mantle surface. At least one elongate wiper blade with a shaft is fastened to the support members so as to extend parallel to the axis of rotation. The at least one wiper blade in its working position projects from the base body in the radial direction. The wiper blade is pivotable out of the working position about a pivot axis defined by the shaft. The wiper blade is made of elastic material.
