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.
