ABSTRACT:
A vehicular apparatus adapted for removing fluids including snow and/or ice and de-icing liquids from a surface as the apparatus traverses the surface. The apparatus comprises: a first container for receiving a first portion of the fluids removed from a zone of the surface; apparatus for collecting and transferring the first portion of the fluids from the zone to the first container; a second container for collecting residual fluids remaining on the zone of the surface after the first portion is removed; apparatus for impinging water at high pressure on the zone of the surface to loosen the residual fluids or make them airborne; and an air sweep connected in fluid communication with the second container for drawing or sweeping the loosened residual fluids and water into the second container concurrently with impinging high pressure water on the surface.
