A sweeping broom apparatus comprises a main body having a debris receiving outlet and connecting means for operat?vely connecting the main body to a vehicle. A broom shroud has an open bottom defined by a bottom edge. The broom shroud has a front end and a back end, and defines a longitudinal horizontal axis extending between the front end and the back end. An airflow obstructing skirt is disposed around the bottom edge of the broom shroud for substantially obstructing the egress of air from between the bottom edge of the broom shroud and the surface being cleaned. There is a forwardly facing debris outlet in the broom shroud for permitting the directed egress of debris therefrom as a forwardly propelled stream of debris. A main sweeping broom is mounted within the broom shroud for propelling debris forwardly from a surface being cleaned generally along the longitudinal horizontal axis, thereby creating a stream of debris propelled forwardly through the forwardly facing debris outlet. There is a source of high speed air having an outlet for permitting the egress of air therefrom. An air blast nozzle has an outlet aimed downwardly and forwardly so as to aim a blast of air at a surface being cleaned, and has an inlet connected in fluid communication to the outlet of the source of high speed air for receiving air therefrom. The inlet is in fluid communication with the outlet, (n use, high speed air from the air blast nozzle is forcibly blasted against a surface being cleaned.
