Abstract
A liquid extraction cleaner includes a solution dispensing system, a liquid recovery system, and an agitation brush assembly. The solution dispensing system includes a supply tank removably affixed to a housing and fluidly connected to a fluid distributor through a trigger-operated manual spray pump. The liquid recovery system includes a recovery tank removably mounted to the housing adjacent to the supply tank. An air liquid separator is provided within the recovery tank. Another assembly within the housing provides a vacuum source, where working air comes from the recovery tank to an inlet between a motor and an impeller. The agitation brush assembly is removably mounted in a lower forward portion of the housing.
