moving the single telescoping boom in three dimensions relative to the support base with a frame, wherein the frame is coupled between the support base and the single telescoping boom and wherein the single telescoping boom is coarsely positionable relative to the tank by moving the trailer, and is finely positionable relative to the tank by moving the frame relative to the support base; moving an articulated arm mounted to the distal end of the single telescoping boom relative to the single telescoping boom, including extending the articulated arm into the interior space; and performing a cleaning operation with the articulated arm upon the interior surface in the interior space. ### Claim 2 (depends on 1) The method of claim 1, further comprising: placing the articulated arm in a stowed configuration outside of the tank; inserting the articulated arm into the interior space while the articulated arm is in the stowed configuration: and moving the articulated arm from the stowed configuration to a deployed configuration while the articulated arm is in the interior space. ### Claim 3 A cleaning system for cleaning an enclosed space, the cleaning system comprising: an articulated arm configured to perform a cleaning operation inside the enclosed space; a single telescoping boom coupled to the articulated arm, wherein the single telescoping boom is the only telescoping portion between a support base and a nozzle, wherein the single telescoping boom is rotatable about a central vertical axis, and wherein the single telescoping boom is operable to adjust a position of the articulated arm, wherein the articulated arm has a stowed configuration in which the articulated arm is folded upon the single telescoping boom such that the articulated arm extends alongside the single telescoping boom, and a deployed configuration in which the articulated arm is unfolded in a different location; a trailer having the support base supporting the single telescoping boom, the single telescoping boom being movable between a retracted position having a first length and an extended position having a second length that is longer than the first length, wherein the single telescoping boom is positioned at least partially above the support base of the trailer in both the retracted position and the extended position, wherein the single telescoping boom extends horizontally with respect to the support base, and wherein the cleaning system is operable from the trailer; and a frame coupled between the support base and the single telescoping boom, wherein the frame is configured to move the single telescoping boom in three dimensions relative to the support base and wherein the single telescoping boom is coarsely positionable relative to the enclosed space by moving the trailer, and is finely positionable relative to the enclosed space by moving the frame relative to the support base. ### Claim 4 (depends on 3) The cleaning system of claim 3, further comprising: a first end effector configured to be coupled to the articulated arm, the first end effector including a nozzle for dispensing a fluid for performing the cleaning operation; and a second end effector configured to be coupled to the articulated arm, the second end effector being interchangeable with the first end effector, the second end effector configured to perform a different type of cleaning operation than the first end effector. ### Claim 5 (depends on 3) The cleaning system of claim 3, further comprising: a control unit configured to control movement of the articulated arm; and a sensor configured to provide a feedback signal to the control unit regarding a state of at least one of the articulated arm or the enclosed space; wherein the control unit is configured to control the movement of the articulated arm based on the feedback signal from the sensor. ### Claim 6 (depends on 3) The cleaning system of claim 3, wherein the frame is movable relative to the support base separately and independently of any movement of the single telescoping boom. ### Claim 7 A tank cleaning system for cleaning an interior surface of a tank, the tank cleaning system comprising: a trailer having a support base transportable by a vehicle, wherein the tank cleaning system is operable from the trailer; an articulated arm configured to extend into the tank and perform a cleaning operation; a single telescoping boom coupled to the articulated arm, wherein the single telescoping boom is the only telescoping portion between the support base and a nozzle, the single telescoping boom being configured to adjust a position of the articulated arm, the single telescoping boom also being movable between a retracted position having a first length and an extended position having a second length that is longer than the first length, the single telescoping boom also being positioned at least partially above the support base of the trailer in both the retracted position and the extended position, wherein the single telescoping boom is rotatable about a central vertical axis, and wherein the single telescoping boom extends horizontally with respect to the support base; a frame coupled between the support base and the single telescoping boom, wherein the frame is configured to move the single telescoping boom in three dimensions relative to the support base and wherein the single telescoping boom is coarsely positionable relative to the tank by moving the trailer, and is finely positionable relative to the tank by moving the frame relative to the support base; at least one fluid line; and the nozzle coupled to the at least one fluid line and the articulated arm, the nozzle being movable by the articulated arm to different positions to discharge fluid to one or more target locations on the interior surface of the tank. ### Claim 8 (depends on 7) The tank cleaning system of claim 7, further comprising: a camera coupled to the articulated arm and movable to different positions to view an environment around the articulated arm. ### Claim 9 (depends on 7) The tank cleaning system of claim 7, further comprising: a camera; and a display communicatively linked to the camera, the display being positioned remote from the camera to view video of an environment around the articulated arm. ### Claim 10 (depends on 7) The tank cleaning system of claim 7, further comprising: a light coupled to the articulated arm and movable to different positions to illuminate an environment around the articulated arm. ### Claim 11 (depends on 7) The tank cleaning system of claim 7, further comprising: a tool operably attached to the articulated arm and moveable by the articulated arm, wherein the tool comprises at least one of scrapers, sanders, fastener tools, or cutting tools. ### Claim 12 (depends on 7) The tank cleaning system of claim 7, further comprising: a water reservoir and a pump supported on the trailer and in fluid communication with the articulated arm to supply water to the articulated arm. ### Claim 13 (depends on 7) The tank cleaning system of claim 7, further comprising: a water reservoir and a pump supported on at least one of a substrate or the ground and in fluid communication with the articulated arm to supply water to the articulated arm. ### Claim 14 (depends on 7) The tank cleaning system of claim 7, further comprising: a cleaning fluid reservoir and a pump on the trailer, the cleaning fluid reservoir and the pump being in fluid communication with the articulated arm to supply cleaning fluid to the articulated arm. ### Claim 15 (depends on 7) The tank cleaning system of claim 7, wherein the articulated arm is extendible from the trailer. ### Claim 16 (depends on 7) The tank cleaning system of claim 7, wherein the articulated arm has two or more degrees of freedom. ### Claim 17 (depends on 7) The tank cleaning system of claim 7, wherein the articulated arm is rotatable about a horizontal axis. ### Claim 18 (depends on 7) The tank cleaning system of claim 7, further comprising: a control unit;
