A debris suctioning and separating apparatus for use in a surface sweeping vehicle having an elongate cylindrically-shaped rotating sweeping broom, a debris receiving and retaining hopper, and a debris conveying mechanism to receive debris from said rotating sweeping broom and convey it to said hopper, comprises a debris separator that is mounted on the surface sweeping vehicle exteriorly to the hopper and has an air inlet for receiving debris-laden air into the debris separator, an air outlet for exhausting separated air from the debris separator, and a debris release outlet for selectively releasing separated debris from the debris separator. A fan is operatively mounted at the air outlet of the debris separator, to draw the debris-laden air through the air inlet and into the debris separator, and to exhaust the separated air from the debris separator to ambient surroundings. A valve is operatively mounted on the debris separator at the debris release outlet, to effect the controlled flow-restricted release from the debris separator of the separated and captured debris, and to preclude the ingress of air and debris into the debris separator through the debris release outlet. Debris is separated from the debris-laden air drawn through said air inlet and into the debris separator, during the operation of the rotating sweeping broom and the debris conveying mechanism.
