The present invention provides a vapor-jet cleaning device that is reduced in size and weight as a whole, makes it easier to check the state of vapor injection and dirt suction, facilitates maintenance, and improves operability. When an operation switch (4) is turned on, steam sucked from a suction channel (2) on a suction nozzle (21) liquefies on an inner peripheral surface of an outer cylinder (31), and sucked water droplets (dirty water) and softened and removed dirt. At the same time, it is collected in the sewage tank 23 from the lower opening 31c. Further, the suction channel 2 is clogged out of the floating dust that is centrifuged from the sucked air, steam, sewage, and dirt into air and other components, and is sucked together with the air into the suction channel on the negative pressure generating unit 25 side. Relatively large floating dust that may possibly be captured is captured by the collection filter 35, and relatively small floating dust is captured by the fan filter 25c. When the operation switch 4 is turned off, the sewage in the sewage tank 23 is prevented from flowing back to the suction nozzle 21 side or the negative pressure generating unit 25 side, and sewage leakage during transportation or the like can be prevented.
