1. A surface cleaning apparatus comprising:

  • a chassis defined by a fore-aft axis and a perpendicular transverse axis, the chassis being supported for transport over the surface along the fore-aft axis, the chassis including a first collecting apparatus attached thereto and configured to collect loose particulates from the surface over a cleaning width disposed generally parallel with the transverse axis, the first collecting apparatus comprising;

    an air jet port configured to expel a jet of air across the cleaning width;

    an air intake port configured to draw air and loose particulates in; and

    a channel formed with generally opposed forward and aft edges, extending generally parallel with the transverse axis across the cleaning width, and generally opposed left and right edges, extending generally orthogonal to said forward and aft edges;

    wherein the air jet port and the air intake port are disposed at opposing ends of the cleaning width with the air jet port expelling the jet of air generally parallel with the surface and generally directed toward the air intake port, and wherein the air jet port is disposed at one of said left and right edges and the air intake port is disposed at the other of said left and right edges.
