The invention relates to a cleaning lance for cleaning the outer skin of aircraft, the bodies of land vehicles, or the hulls of boats. The device has a cleaning head (14) which is arranged on the free end of a longitudinally extended, tubular shaft (16) and which comprises a cleaning tool (21). Said cleaning tool can be driven in a rotating or oscillating manner by means of an electric motor (62). The cleaning head (14) is pivotally mounted around an axis (19). Said axis (19) is perpendicular to the central longitudinal axis (18) of the cleaning lance (10), preferably runs at a right angle thereto, and intersects the same. A locking device (32, 47) is provided which enables the cleaning head (14) to be locked in defined orientations with regard to the lance shaft (16) in such a way that it can be unlocked. A spraying device (75) is provided which enables cleaning liquid to be sprayed into the working area of the cleaning head (14). |
