a supply tank;
a cleaning fluid distributor in fluid communication with the supply tank and configured to dispense cleaning fluid;
a base adapted to move over a surface to be cleaned, the base comprising:
a base housing comprising a brush chamber;
a brushroll mounted on the base housing in the brush chamber and adapted to contact the surface to be cleaned to sweep dirt and liquid;
a collection bin configured to receive dirt and liquid swept by the brushroll;
a debris outlet in at least one of the base housing and collection bin; and
a cleanout member configured to force dirt and liquid through the debris outlet, the cleanout member comprising a wiper configured to wipe an internal surface of the base, whereby movement of the cleanout member drives the wiper to mechanically remove dirt and liquid accumulated on the internal surface of the base that may otherwise be trapped within the base.
