A vacuum cleaning robot for a duct is provided to improve working efficiency and improve cleaning effect without scattering of dust when cleaning the inside of duct by sucking the dust and discharging into the outside through the vacuum fan and the suction pipe communicated by the vacuum fan. A vacuum cleaning robot for a duct is composed of: a body(10) installed with four wheels(13) at both sides and formed with an endless-track 360‹-rotated by the drive of the wheels; a connecting device(20) whose inside is hollow and coupled by both support devices; a suction pipe(30) whose one side is fitted to the front end of the connecting device and communicated with the hollow inside of the connecting device, and mounted with a suction port(31) sucking dust in the duct; a corrugated pipe(40) whose one side is fitted at the rear end of the connecting device and the other side is fitted/communicated with a suction part of a vacuum fan placed in the body; and a lighting part(50) supported by a bracket(51) and formed with a camera(52) and a lighting lamp(53). A left and right rotating part(60) is placed with a left and right rotating motor mounted at the upper end of the connecting device.
