<p>The invention concerns a vacuum cleaner dusting brush comprising a housing (10) capable of being connected to a suction tube via a connection sleeve (12), a bearing plate (14) located beneath the housing and having a suction channel (18), a suction aperture (16) located in the suction channel (18), a scraping member (28) located beneath the housing and rear wheels (24, 26), the coupling sleeve (12) pivot pin being located behind the axis of rotation (A) of said wheels and coinciding therewith. The scraping member (28) is fixed and continuously projects beneath the bearing plate, the resting plane (PS) of the dusting brush on the floor being defined by contact zones of the rear wheels (24, 26) and of the scraping member (28) with the floor and the bearing plate assembly being located recessed relative to said resting plane. The scraping member (28) only extends in the dusting brush longitudinal zone which, viewed relative to the suction aperture rear edge, is located at the dusting brush front.</p> |
