Sweeping apparatus with sweeping roller

Abstract

In a sweeping apparatus with a sweeping roller arranged substantially horizontally to a sweeping surface and a storage bin for swept material fixable to the sweeping apparatus and which has a sweeping edge facing the sweeping roller, the sweeping edge is movable relative to the sweeping roller in such a way that the vertical position of the sweeping edge with respect to the sweeping surface is independent of the vertical position of the sweeping roller with respect to the sweeping surface. The storage bin or collecting container is preferably pivotably mounted, so that the bin or container is moved together with the sweeping roller and the sweeping edge is always guided close to the ground and bristles.
