Abstract

Abstract A portable cleaning head comprising part of apparatus for cleaning carpets and the like wherein cleaning solution is supplied under pressure from a reservoir system via a cleaning solution supply hose to the cleaning head for spraying onto a carpet and the cleaning head is adapted to be coupled to a vacuum hose connected to a vacuum pick-up system for picking up via the cleaning head and storing cleaning solution applied to the carpet. The cleaning head comprises a floor head assembly and a handle assembly pivotally attached at one end to the floor head assembly and having hand grips at its other end. The floor head assembly contains sprayer means, suction nozzle means and solenoid actuated valve means to control the supply of cleaning solution to the sprayer means. The handle assembly includes two hand grips rigidly carried by two hollow elongated members, an electrical plug and an on-off switch located adjacent the hand grips for coupling the cleaning head to a source of electrical current via a power cord or the like, electrical conductors disposed within one of the hollow elongated members coupling the solenoid to the electrical plug, and fluid coupling means carried by the other hollow elongated member for coupling the sprayer means to the cleaning solution supply hose via this elongated member. A hose is provided between the elongated member and the sprayer means.
