    摘要: An extractor includes a fluid recovery system including a suction nozzle, a recovery tank assembly, and a suction source having an inlet fluidly connected to the recovery tank assembly and the suction nozzle through an air conduit and adapted to draw liquid through the suction nozzle and deposit the liquid in the recovery tank assembly. The extractor includes a body provided with the air conduit for movement between a first position wherein suction is unreduced and a second position wherein suction is reduced. The extractor includes a fluid delivery system including a solution supply tank assembly, a fluid distributor, and a conduit for depositing fluid onto a surface. The extractor includes a hydraulic connector operably coupled to the body and adapted to move the body between the first and second positions.
