Abstract: A fluid jet cleaning system, particularly adapted for household use, comprises an elongated flexible hose coupled at one end through a quick-operating on-off valve to a source of pressurized water and whose other end contains a jet nozzle assembly including a head having an ejector opening for discharging a high velocity jet stream for dislodging collected debris and a rotatable spinner sleeve containing tangential openings for emitting additional jet streams that rotate and that flush the debris and provide a secondary cleansing of the drain wall surface.
