Abstract
A robot is disclosed for cleaning the exterior of tubes of a heat exchanger. The robot comprises a lance for directing a jet of fluid into spaces between the tubes, a carriage for transporting the lance in a direction of travel parallel to axes of the tubes of the heat exchanger, and traction assemblies for engaging the tubes to enable the carriage to be advanced along the tubes, wherein the traction assemblies are each moveable relative to the carriage in a direction transverse to that of travel in order to change the track width of the robot.
