A head () for a vacuum cleaning device includes a central airflow conduit (), first and second flexible tubular appendage (), and a cross member (). Each tubular appendage includes an internal channel () connected to a surface channel () via a plurality of ingress vents (). A cross member () structurally connects the first and second flexible tubular appendages such that a cross-connecting airflow channel provides airflow from the first and second tubular appendages to the central airflow conduit. The first and second flexible appendage are attached at an apex () to form an A-shaped structure with the cross member. 1200.
