Abstract
A vacuum cleaner head carries an array of brush bristles in conventional fashion. The bristles surround an inlet through which dust and debris are sucked into the vacuum cleaner during normal brushing action. A skirt is mounted inside the bristles so that when the head is pressed sufficiently towards a brushing surfaces a lower edge of the skirt can contact directly against the brushing surface.
Claims1
A vacuum cleaner comprising:
- a housing which has a lower generally planar surface and a central inlet to which a vacuum is applied to draw dust and debris into the housing for collection;
- a brush head that fits against the planar surface and carries an array of brush bristles surrounding the central inlet with the bristles extending downwards from the planar surface for contacting a brushing surface in use;
- a skirt surrounding the inlet that extends downwards inside the array of bristles with a peripheral bottom edge, adjacent the bristles contacting directly against the brushing surface when the head is pressed sufficiently firmly downwards to laterally flex the bristles, the skirt formed with vertical slits to allow the bottom edge to flex so as to conform to non-planar brushing surfaces when required.
