Air duct cleaning apparatus

A duct cleaning system comprising:

• a flexible, coilable vacuum hose having a distal end and a proximal end and a first longitudinal axis extending therebetween, the proximal end of the vacuum hose configured to couple to a vacuum source;
• a flexible, coilable drive shaft having a distal end and a proximal end and a second longitudinal axis extending therebetween, the proximal end of the drive shaft configured to couple to and be rotatably driven by a motor, the distal end of the drive shaft configured to couple to a cleaning attachment;
• and
• a flexible, coilable camera line having a distal end and a proximal end and a third longitudinal axis extending therebetween, the proximal end configured to couple to a power source, the distal end provided with a camera;
• wherein the first longitudinal axis, the second longitudinal axis, and the third longitudinal axis are non-coaxial;
• wherein the vacuum hose, the drive shaft, and the camera line are loosely coupled together by at least one slidable collar positioned between the distal end and the proximal end of each of the vacuum hose, the drive shaft, and the camera line;
• wherein the distal end of the vacuum hose, the distal end of the drive shaft, and the distal end of the camera line are configured to be fed into and independently moved along a duct to be cleaned, and wherein the vacuum hose delivers a vacuum to the duct to be cleaned, the drive shaft and cleaning attachment rotate within the duct to be cleaned, and the camera line provides visualization of the duct to be cleaned;
• and
• wherein each of the vacuum hose, the drive shaft, and the camera line are configured to be coiled around a first spool, a second spool, and a third spool, respectively, for storage and are configured to extend from the first spool, the second spool, and the third spool, respectively, in use, the first spool, the second spool, and the third spool being arranged in parallel with one another within a carrying case.
