         2 . The surface cleaning apparatus of  claim 1 , wherein the wiring harness is isolated from the fluid conduit. 
     
     
         3 . The surface cleaning apparatus of  claim 1 , wherein the fluid conduit is routed through the first leg and the wiring harness is routed through the second leg. 
     
     
         4 . The surface cleaning apparatus of  claim 1 , wherein the first and second legs are coupled to the base. 
     
     
         5 . The surface cleaning apparatus of  claim 1 , wherein the upright body is pivotally mounted to the base, and lower ends of the first and second legs are pivotally coupled with the base. 
     
     
         6 . The surface cleaning apparatus of  claim 1 , wherein the yoked spine section comprises an inverted U-shape, with the first and second legs spaced apart and generally parallel to each other. 
     
     
         7 . The surface cleaning apparatus of  claim 1 , wherein the suction source comprises a motor/fan assembly provided in the base, and the wiring harness is configured to supply power to the motor/fan assembly. 
     
     
         8 . The surface cleaning apparatus of  claim 7 , comprising a power button operably coupled with a switch to selectively activate the motor/fan assembly, wherein the power button is disposed on the yoked spine section. 
     
     
         9 . The surface cleaning apparatus of  claim 7 , comprising a power source electrically coupled to the motor/fan assembly, wherein the power source comprises a power cord extending from the yoked spine section. 
     
     
         10 . The surface cleaning apparatus of  claim 1 , wherein the fluid delivery system comprises a pump disposed in the base, and the fluid conduit fluidly couples the supply tank to the pump. 
     
     
         11 . The surface cleaning apparatus of  claim 10 , wherein the upright body comprises a supply tank receiver supporting the supply tank on the upright body, the supply tank receiver having a valve seat, wherein the fluid conduit carries cleaning fluid from the valve seat to the pump. 
     
     
         12 . The surface cleaning apparatus of  claim 10 , wherein the wiring harness is configured to supply power to the pump. 
     
     
         13 . The surface cleaning apparatus of  claim 1 , wherein the upright body comprises a frame supporting the supply tank and comprising the yoked spine section, wherein the handle extends upwardly from the frame. 
     
     
         14 . The surface cleaning apparatus of  claim 1 , wherein the upright body comprises a supply tank receiver supporting the supply tank on the upright body, wherein the supply tank receiver is disposed at a top of the yoked spine section. 
     
     
         15 . The surface cleaning apparatus of  claim 1 , wherein the recovery tank is removably mounted on the base, with the first and second legs straddling the recovery tank. 
     
     
         16 . The surface cleaning apparatus of  claim 1 , comprising:
 a recovery tank receiver provided on the base, wherein the recovery tank is removably mounted in the recovery tank receiver; and   a recovery tank latch to secure the recovery tank to the recovery tank receiver.   
     
     
         17 . The surface cleaning apparatus of  claim 16 , wherein the latch is a biased latch configured to release the recovery tank upon application of a sufficient force to overcome a biased latching force of the biased latch. 
     
     
         18 . The surface cleaning apparatus of  claim 16 , wherein the latch is a spring-biased latch. 
     
     
         19 . The surface cleaning apparatus of  claim 16 , wherein the recovery tank receiver includes a pocket that centers and secures a rear portion of the recovery tank within the recovery tank receiver. 
     
     
         20 . The surface cleaning apparatus of  claim 1 , wherein the surface cleaning apparatus is an upright extraction cleaner.
