ABSTRACT:
A cleaning implement for cleaning a soiled surface having soiling particles lodge therein includes a body having a cleaning surface defining first and second cleaning section. The first and second cleaning sections are provided respectively with first and second dislodging bristles for dislodging the soiled particles from the soiled surface. The first and second cleaning bristles are configured and positioned so that the dislodging action is performed more efficiently when the first and second cleaning section are move relative to the soiled surface respectively in a first and a second direction as opposed to other directions. The implement is connectable to a vacuum source for suctioning the soiling particles having been dislodged by the first and second cleaning surfaces.
