A surface cleaning vehicle comprises an air blast outlet or a rotating sweeping broom for effecting a forwardly propelled stream of debris from a contacted portion of a surface being cleaned. A debris chute has a rearwardly facing inlet positioned to receive the forwardly propelled stream of debris thereinto and that is connected in fluid communication via an interior passage with an elevated outlet. An airflow is effected in the interior passage of the debris chute from the inlet to the outlet, thereby augmenting travel of the forwardly propelled stream of debris along the interior passage of the debris chute toward the outlet and into a hopper. Alternatively, a surface cleaning and debris loading apparatus additionally comprises an open-bottom pick-up head defining an interior, and having an outlet disposed at the front of the hood for receiving a substantially rearwardly facing inlet of a debris chute in fluid communication with the interior, and for permitting the egress of debris from the hood, through the outlet and to the substantially rearwardly facing inlet of the debris chute. Also alternatively, a deflector flap is disposed forwardly of the air blast outlet or a rotating sweeping broom in debris deflecting relation to the inlet of the debris chute, to deflect the forwardly propelled stream of debris beyond the deflector flap upwardly and forwardly into an upwardly and forwardly disposed portion of the debris chute.
