Apparatus for cleaning stacked vessels with low head clearance

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