Abstract

See full text

The invention relates to a mobile sweeper comprising a housing, in which a sweeping roller driven by an electric motor is mounted for rotation, and a sweepings container for receiving sweepings, wherein there are mounted on the housing adjacent to the sweeping roller two front supporting wheels and at a distance from these at least one rear supporting wheel, each for rotation about an axis of rotation. In order to further develop the sweeper such that with the occurrence of surface unevennesses, there is no risk of the sweeping roller becoming blocked or of the sweeper tilting, it is proposed in accordance with the invention that the axis of rotation of a first front supporting wheel be arranged coaxially with the axis of rotation of the sweeping roller and, in relation to the main direction of movement of the sweeper, offset from the axis of rotation of the second front supporting wheel.
