摘要:
The invention is a cleaning tool housing assembly and a replaceable cleaning assembly. The manifold, in combination with a fluid intake element, also delivers fluid (under pressure through holes in the manifold located in a longitudinal channel) to a sponge. Two spaced apart fluid barriers are longitudinally disposed in the sponge. As fluid is introduced into the center of the sponge, between the fluid barriers, the fluid travels toward the opposite surface of the sponge. The fluid is prevented from traveling laterally due to the fluid barriers. As vacuum pressure, negative pressure, is exerted on the outer portions of the sponge (on each side of the fluid barriers), fluid is pulled back through the sponge, through the manifold and through the nozzles into the hollow housing body.
