<p>Apparatus for cleaning bins (B) includes a lance (44) provided with a nozzle assembly (74) for discharging cleaning fluid (and optionally drying air) towards the inner wall surfaces of a bin, the lance being advanced into and retracted from the bin while undergoing lateral displacement to maintain the nozzle assembly in close proximity with the inner wall surfaces during cleaning (and optionally drying). The lance may have a rastering mode of operation which is used when the forward end of the lance is adjacent the base of the bin.</p> |
