1. A method of cleaning elongated tubes comprising: positioning a terminal end of at least one lance adjacent an opening to an elongated tube bore; rotating the at least one lance about an axis utilizing a rotation mechanism; supporting the at least one lance with one or more trolleys engaged on a support rail forwardly of the rotation mechanism; activating a translation mechanism; moving linearly, with the translation mechanism, the rotation mechanism and the at least one lance in a first direction along the support rail: advancing the at least one lance in the first direction toward the opening and into the elongated tube bore; moving the one or more trolleys along the support rail as the translation mechanism moves the at least one lance and the rotation mechanism in the first direction; stacking the one or more trolleys on a stacker when the one or more trolleys are moved in the first direction; operatively engaging the stacker with one of the translation mechanism and the rotation mechanism; defining a channel in each of the one or more trolleys; and selectively receiving the stacker through the channel of one of the one or more trolleys when the translation mechanism moves the rotation mechanism in the first direction.
