The base includes a suction nozzle and an aperture configured to spray the cleaning fluid onto the surface. The extractor cleaning machine also includes a recovery tank in fluid communication with the suction nozzle and a suction source in fluid communication with the suction nozzle and the recovery tank. The suction source is configured to draw the cleaning fluid through the suction nozzle and into the recovery tank. The extractor cleaning machine further includes a body pivotally coupled to the base between an upright position and an inclined position. The body includes an outlet in fluid communication with the suction source such that an airflow generated by the suction source is discharged from the outlet toward the surface. ## Claims ### Claim 1 An extractor cleaning machine comprising: a supply tank configured to store a cleaning fluid; a base configured to be movable along a surface to be cleaned, the base including a suction nozzle and an aperture configured to spray the cleaning fluid onto the surface; a recovery tank in fluid communication with the suction nozzle; a suction source in fluid communication with the suction nozzle and the recovery tank, the suction source configured to draw the cleaning fluid through the suction nozzle and into the recovery tank; and a body pivotally coupled to the base between an upright position and an inclined position, the body including an outlet in fluid communication with the suction source such that an airflow generated by the suction source is discharged from the outlet toward the surface. ### Claim 2 (depends on 1) The extractor cleaning machine of claim 1, wherein the body includes a body exhaust duct in communication with the airflow discharged from the outlet of the body, and wherein the body exhaust duct directs the airflow from the outlet toward the surface. ### Claim 3 (depends on 2) The extractor cleaning machine of claim 2, wherein the body includes a motor housing supporting the suction source, and wherein the body exhaust duct is coupled to the motor housing. ### Claim 4 (depends on 3) The extractor cleaning machine of claim 3, wherein the motor housing is cylindrical. ### Claim 5 (depends on 1) The extractor cleaning machine of claim 1, wherein the airflow discharged from the outlet is a cooling airflow of the suction source, and wherein the cooling airflow does not travel through the recovery tank. ### Claim 6 (depends on 5) The extractor cleaning machine of claim 5, wherein the body includes a body exhaust duct in communication with the cooling airflow discharged from the outlet of the body, and wherein the body exhaust duct directs the cooling airflow from the outlet toward the surface. ### Claim 7 (depends on 1) The extractor cleaning machine of claim 1, wherein the airflow discharged from the outlet is a primary airflow configured to draw the cleaning fluid through the suction nozzle and into the recovery tank. ### Claim 8 (depends on 1) The extractor cleaning machine of claim 1, wherein the airflow is discharged from the extractor cleaning machine in a first direction relative to the base while the body is in the upright position, and wherein the airflow is discharged from the extractor cleaning machine in a second direction different from the first direction relative to the base while the body is in the inclined position. ### Claim 9 (depends on 1) The extractor cleaning machine of claim 1, wherein the outlet is a first outlet of the body, wherein the airflow is a primary airflow configured to draw the cleaning fluid through the suction nozzle and into the recovery tank, wherein the body includes a second outlet in fluid communication with the suction source such that a cooling airflow generated by the suction source is discharged from the second outlet toward the surface, and wherein the cooling airflow does not travel through the recovery tank. ### Claim 10 (depends on 9) The extractor cleaning machine of claim 9, wherein the body includes a body exhaust duct in communication with the primary airflow and the cooling airflow, and wherein the body exhaust duct directs the primary airflow and the cooling airflow toward the surface. ### Claim 11 (depends on 10) The extractor cleaning machine of claim 10, wherein the body includes a motor housing supporting the suction source, and wherein the body exhaust duct is coupled to the motor housing. ### Claim 12 (depends on 11) The extractor cleaning machine of claim 11, wherein the motor housing is cylindrical. ### Claim 13 A floor cleaning machine comprising: a base configured to be movable along a surface to be cleaned, the base including a suction nozzle; a suction source in fluid communication with the suction nozzle, the suction source configured to draw debris through the suction nozzle; a body pivotally coupled to the base between an upright position and an inclined position, the body including an outlet movable relative to the base as the body pivots between the upright position and the inclined position, the outlet in fluid communication with the suction source to discharge an airflow generated by the suction source, wherein the airflow is discharged from the floor cleaning machine toward the surface in a first direction relative to the base while the body is in the upright position, and wherein the airflow is discharged from the floor cleaning machine toward the surface in a second direction different from the first direction relative to the base while the body is in the inclined position. ### Claim 14 (depends on 13) The floor cleaning machine of claim 13, wherein the body includes a body exhaust duct in communication with the airflow discharged from the outlet of the body, and wherein the body exhaust duct directs the airflow from the outlet toward the surface. ### Claim 15 (depends on 14) The floor cleaning machine of claim 14, wherein the body includes a motor housing supporting the suction source, and wherein the body exhaust duct is coupled to the motor housing. ### Claim 16 (depends on 15) The floor cleaning machine of claim 15, wherein the motor housing is cylindrical. ### Claim 17 (depends on 13) The floor cleaning machine of claim 13, wherein the airflow discharged from the outlet is a cooling airflow of the suction source, and wherein the cooling airflow does not travel through the suction nozzle. ### Claim 18 (depends on 17) The floor cleaning machine of claim 17, wherein the body includes a body exhaust duct in communication with the cooling airflow discharged from the outlet of the body, and wherein the body exhaust duct directs the cooling airflow from the outlet toward the surface. ### Claim 19 (depends on 13) The floor cleaning machine of claim 13, wherein the airflow discharged from the outlet is a primary airflow configured to draw the debris through the suction nozzle. ### Claim 20 (depends on 13) The floor cleaning machine of claim 13, wherein the outlet is a first outlet of the body, wherein the airflow is a primary airflow configured to draw the debris through the suction nozzle, wherein the body includes a second outlet in fluid communication with the suction source such that a cooling airflow generated by the suction source is discharged from the second outlet toward the surface, and wherein the cooling airflow does not travel through the suction nozzle.
