Device for cleaning the interior of elongated tanks or tanks where access to the interior is limited consisting of a tank cleaning machine attached to a source of cleaning liquid. The tank cleaning machine is movably affixed to a track and drives along the track during the cleaning operation, the track extending through the area of the tank to be cleaned so that the cleaning operation extends to portions of tank interior where access from the outside is limited. An externally mounted gas tight winch is preferred as the drive means. A flexible hose provides connection between the tank cleaning machine and the source of cleaning liquid and the hose may be calibrated so that the position of the tank cleaning machine within the tank can be determined. Entry to the tank interior for mounting and dismounting the tank cleaning machine on the track is through an entry port located adjacent one end of the track.
