ABSTRACT:
A surface-cleaning apparatus, especially for street cleaning and the cleaning of industrial surfaces, comprises an array of high-pressure water nozzles surrounding a pick-up nozzle whose open end is formed with a flow accelerating hood, the pressure nozzle surrounding this hood being constituted as drive nozzles whose water sprays are trained beneath the collecting nozzle. The collecting nozzle is connected to a suction source which draws the dirty water upwardly after the water is reflected from the surface to be cleaned. The device is mounted upon a vehicle or is displaceable by a vehicle.
