摘要: A cleaning machine extractor head configured to withdraw fluid from a carpeted surface is disclosed herein. The extractor head has an elongated base plate to be placed over a carpeted surface for removing cleaning liquid, water, other fluids, dirt, and other contents. The extractor head has a tapering cross section with a flat wide upper surface and a narrow lower surface and a plurality of apertures extending from the upper surface to the lower surface. Each aperture is beveled at the lower surface. The extractor head may further include a trough on the upper surface.

摘要: An apparatus, system, and method for dual-mode vehicle-mounted cleaning are provided. In one embodiment, the apparatus includes a heat-exchanger subsystem having first and second heat-receiving pathways and a heat-providing pathway. Heat exhaust from a combustion engine is routed through the heat-providing pathway to transfer heat to both the first and second heat-receiving pathways. The first heat-receiving pathway, the second heat-receiving pathway, and the heat-providing pathway are fluidly independent of each other. The apparatus also includes a first liquid pathway fluidly coupled to the first heat-receiving pathway, configured to direct a hard-surface cleaning liquid, by a first pump, through the first heat-receiving pathway to a hard-surface cleaning tool, and a second liquid pathway fluidly coupled to the second heat-receiving pathway, configured to direct a soft-surface cleaning liquid, at a lower pressure than a first liquid in the first liquid pathway, through the second heat-receiving pathway to a soft-surface cleaning tool.
