Abstract: A surface cleaning apparatus is provided with a primary fluid distributor and an auxiliary fluid distributor. Each distributor can have a separate and independent flow control actuator. The flow control actuator for the auxiliary fluid distributor is operably coupled with a push-push flow control mechanism, where push-push flow control mechanism has a push on/push off configuration such that pushing the auxiliary flow control actuator once starts fluid flow from the auxiliary fluid distributor and subsequently pushing the auxiliary flow control actuator again stops fluid flow from the auxiliary fluid distributor.
