1. An extraction cleaner for a floor surface, comprising:
- a housing having a base assembly for movement across the floor surface and a handle assembly pivotally mounted to a rearward portion of the base assembly for directing the base assembly across the floor surface;
a fluid delivery system supported by the housing for storing cleaning fluid and delivering the cleaning fluid to the floor surface, comprising;
a fluid supply container for storing a supply of cleaning fluid; and
at least one fluid distributor in fluid communication with the supply container and comprising an outlet for depositing a cleaning fluid onto the floor surface;
a fluid recovery system supported by the housing for removing the spent cleaning fluid and dirt from the floor surface and storing the spent cleaning fluid and dirt, comprising;
a recovery tank for storing spent cleaning fluid and dirt that is recovered from the floor surface;
an extraction nozzle extending towards a surface to be cleaned and in fluid communication with the recovery tank; and
a suction source in fluid communication with the recovery tank and configured to generate a working airflow through the extraction nozzle and into the recovery tank; and
a modular unit that is removably mounted to the base assembly, the modular unit including the at least one fluid distributor and the extraction nozzle, wherein the outlet of the at least on fluid distributor is positioned internal to the modular unit;
wherein the at least one fluid distributor and the extraction nozzle are simultaneously removable from the base assembly by removal of the modular unit from the base assembly.
