1. An extractor comprising:
a base movable along a surface to be cleaned;
a liquid distribution system including a supply tank and a distributor in fluid communication to deliver solution to the surface;
an encoder operable to generate a signal in response to user-initiated movement of the base along the surface; and
a controller operatively connected to the encoder and the liquid distribution system, the controller being configured to operate in a distributing mode during movement of the base and in a non-distributing mode during movement of the base in response to the signal during operation of the extractor, wherein the distribution of the solution is independent of user interaction with the extractor other than the user-initiated movement,
wherein the signal is indicative of a speed of rotation of a wheel, and
wherein the distribution of the solution is increased or decreased in response to a respective increase or decrease of the speed of rotation of the wheel during operation of the extractor.
