Abstract Laid carpeting is hydromechanically cleaned in place by traversing successively adjacent areas with obliquely directed high-pressure, and high-frequency, low-amplitude pulsated, jet sprays of cold or lukewarm water, with or without a dissolved non-foaming cleanser, and simultaneous suction pick-up of dirtladen water immediately after application to remove the greater part of applied water; optionally followed by warm air current drying or residual moisture. A clean water reservoir tank, dirty water tank, electric motor driven high pressure double acting piston pump and electric motor-suction fan unit, carried on a wheeled cart form a portable cleaner unit power-cord-connectable to local electric mains but independent of fixed water supply and drain services; which through flexible hoses delivers the pulsating high pressure water to and draws dirty water from respectively a jet nozzle array and suction pick-up nozzle separably mounted on a stick type hand implement including user manipulated controls.
A METHOD FOR IN SITU CLEANING CARPETING OR TEXTILE FLOOR COVERING COMPRISING THE STEPS OF HIGH-PRESSURE JET-SPRAYING WATER AT A PRESSURE OF FROM ABOUT 31 TO 36 ATMOSPHERES ON AND THEREBY INTO THE CARPETING TO BE CLEANED WITH THE WATER JET FLOW BEING A RAPIDLY PULASATING FLOW, AND IMMEDIATELY THEREAFTER VACUUM SUCTIONING OFF FROM AND OUT OF THE CARPETING THE MAJOR PART OF THE APPLIED WATER AND DIRT CONTAINED THEREIN.
