Abstract:
1. A pressure washing system, comprising: a first pump operable to produce a flaw of a first liquid at a pressure of at least 600 p.s.i.g.; a storage tank operable to store a second liquid; a second pump operable to produce a flow of second liquid from the storage tank; and a wand assembly coupled to the first pump and to the second pump, the wand assembly comprising a first wand, wherein the wand assembly is adapted to produce a spray of first liquid in an axial direction relative to the first wand and a spray of second liquid that is directed towards the spray of first liquid in a second direction relative to the first wand, the axial direction and the second direction being different, such that the spray of second liquid is entrained in the spray of first liquid and thereby re-directed to travel in the axial direction relative to the first wand.
