<p>The device has a sliding element guidable over a floor to be cleaned and held at free ends of bar-shaped pushing units e.g. link chains (7), where the sliding element is formed as a rake blade (8). A force device i.e. electromotor (4), provides pushing force and tensile force for acting on the pushing units and is arranged outside of the floor. The force device is arranged in a chassis (1) that is movable along the floor, where the chassis has a retaining device i.e. batcher (10), for retaining sections of the pushing units.</p> |
