Abstract
An attachment for a vacuum cleaning appliance includes a head and a handle connected to the head. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. A conduit is connectable to a vacuum cleaning appliance for conveying an air flow towards the appliance. The head includes a first suction opening of the conduit and the handle includes a second suction opening of the conduit. An actuator effects relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures.
