ABSTRACT:
A drive for rotating a corner-sweeping brush of a sweeping device includes a gear on the brush, and a translation member provided with teeth engaging the gear and rotating the same about its axis with attendant rotation of the brush when the housing of the sweeping device comes into contact with an obstruction during its forward movement. An actuating member is connected to the translation member under interposition of a time-delay unit, and moves the translation member into engagement with the gear and subsequently toward an extended position thereof with concomitant rotation of the brush so that dirt is removed from the corner region of the surface being swept, even after the housing of the sweeping device has come to a standstill. The actuating member may be connected to a handle of the sweeping device, or it may be a discrete element projecting forwardly or upwardly out of the housing.
