Abstract
To adjust a brush roller to the current operating conditions, a brush attachment to hold the brush roller and drive mechanism is realized in the form of an upper part and a separate inner part. The inner part is thereby mounted in the upper part so that the inner part can pivot by means of an axle, and the brush roller is pressed against the surface to be cleaned by means of a spring element. The inner part has a suction chamber for the brush roller, and has a rear floor strip, preferably of convex curvature, in the vicinity of the axle to create a seal. The front area is sealed by means of a floor strip on the brush attachment.
