Abstract: A cleaning device includes a suction device configured to suck a pollutant into the suction device; a body configured to collect the sucked pollutant, wherein the suction device includes: a drum rotatable around an axis and having a hollow portion, a driving motor disposed in the hollow portion of the drum and configured to apply a rotational force to the drum to rotate the drum around the axis, a rotatable chamber surrounding the driving motor and disposed between the drum and the driving motor, the rotatable chamber rotatable coaxially with the axis and configured to rotate with the drum so that a cooling fluid between the driving motor and the rotatable chamber spirals around the driving motor when the drum is rotated, and a cooling fluid discharge hole at an end of the rotatable chamber to discharge the cooling fluid outside of the rotatable chamber.
