Claim 4:
5. A method of cleaning a plurality of tubes of a heat exchanger comprising:
positioning a fluid jet machine proximate a heat exchanger to be cleaned;
providing a hand-held computer to an operator located in the immediate vicinity of the fluid jet machine;
operatively linking the fluid jet machine to the computer;
installing programming in the computer that controls the fluid jet machine and a cleaning operation using the fluid jet machine via the hand-held computer;
performing a set-up procedure controlled by the human operator using the hand-held computer;
learning with the computer, a pattern of the plurality of tubes of the heat exchanger from the set-up procedure by initiating the programming of the computer, wherein openings to the plurality of tubes are arranged in an X-Y grid with each opening in the X-Y grid having X-Y coordinates, and wherein the pattern learned by the programming is the arrangement of the openings in the X-Y grid;
performing the cleaning operation following the learned pattern while the operator monitors and controls the fluid jet machine via the hand-held computer.
