Abstract
A cleaning lance provided in which water from an inlet is directed either to an upper, rinsing barrel or to a lower, foamer barrel. The latter is provided with a mixing chamber having an inlet for detergent supplied via a flow control valve. A water jet injected into the mixing chamber via a venturi nozzle draws in and mixes with the detergent and the resulting mixture is ejected by a further venturi nozzle and draws in air from an exterior air inlet to form a jet of cleaning foam.
