A nozzle 23,24 for a rear suction assembly (20,fig.2) for a road cleaning vehicle (10,fig.1) comprises a nozzle housing 40 forming a nozzle chamber 41 extending and converging between a nozzle inlet 42 and a nozzle outlet 43. Guide walls 65-69 are mounted in the chamber to form a plurality of passageways 70-75 between the walls for dividing air flowing between the inlet and outlet. The housing width may be narrower at the outlet, and the housing depth may be greater at the outlet. The rear suction assembly may comprise two nozzles having inlets mounted adjacent to one another with a separator element mounted in the gap in between the inlets for dividing airflow between the first and second nozzle inlets. A skirt 90 may extend around the perimeter of the bottom of the first and second nozzle openings to improve air flow into the nozzles.
