A surface cleaner system includes a base assembly having a housing movable along a surface, a pump supported by the housing and operable to pressurize a fluid, and a prime mover supported by the housing. The prime mover is coupled to the pump to drive the pump. The surface cleaner system also includes a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface. The surface cleaner system further includes a spray gun in fluid communication with the pump to receive pressurized fluid from the pump. The spray gun includes an outlet portion that is connectable to the base assembly to direct the pressurized fluid from the pump into the spray assembly. When the outlet portion is disconnected from the base assembly, the spray gun discharges the pressurized fluid from the pump toward the surface without directing the pressurized fluid into the spray assembly.
