Apparatus for cleaning stacked vessels with low head clearance

An apparatus 20 for cleaning vessels 10 stacked on racks 12 with a minimum of head clearance H. The cleaning apparatus 20 has a drive unit 30 with a turbine wheel connected to a multi-stage gear train. The output motion of the gear train connects through an angular transmission 54, 56 within a fluid conveying elbow 50 to a rotatable housing 36 having a rotatable nozzle 38 angularly assembled thereto. The elbow 50 has a pressure channel 82 and a suction channel 92 therethrough. The length of the apparatus from the elbow 50 to the housing 36 is short enough to be passed into the bunghole 14 of a vessel 10, e.g. a wine barrel, while racked. A flexible suction hose 26 is connected to a suction line 92 in the apparatus 20 for removing spent cleaning fluid from within the vessel 10.
