A mechanical surface sweeping vehicle comprises a cylindrically-shaped rotating sweeping broom to propel forwardly debris disposed on a contacted portion of a surface being cleaned, thereby creating a forwardly propelled stream of debris. A mechanical debris elevator is disposed to receive and retain the forwardly propelled stream of debris and to deposit the received and retained debris into the hopper. A deflector flap is disposed forwardly of the rotating sweeping broom and immediately rearwardly of the debris accepting lower end portion of the mechanical debris elevator, to receive at least a portion of the forwardly propelled stream of debris and to deflect it upwardly and forwardly onto the mechanical debris elevator. An air blast outlet effects a blast or air forcefully impinges in a forward direction the surface behind the leading edge of the broom, thereby propelling forwardly therewith fine debris disposed on the surface, and carries forwardly through the sweeping broom and egresses therefrom, to deflect forwardly and upwardly off the deflector flap and forwardly past the deflector flap to travel to the mechanical debris elevator, in a path having a forward component along its entire length, exclusive of subsequent impingement of the surface and exclusive of subsequent re-entry into the lower portion of the broom.
