PROBLEM TO BE SOLVED: To improve the utilization convenience of a cleaning tool using compressed air by sufficiently increasing the suction force. SOLUTION: The cleaning tool 1 comprises a cylinder 3 provided with a path 2 wherein foreign matters pass; a foreign matter storage box 5 attached to the rear end of the cylinder 3 in a detachable manner; a check valve 8; a ventilation hole 9 formed in the storage box 5; a first jetting pipe 11 installed at the tip end of the cylinder 3 in such a manner that the jetting port 11a faces to the outside of the cylinder 3; a second jetting pipe 12 installed in the inside of the tip end of the cylinder 3 in such a manner that the jetting port 12a faces to the inside of the cylinder 3; and a switch valve 13 connected to both jetting pipes. Since air pressure is used only for either blowing or sucking, powerful action can be performed. Since air is blown inward to the inside of the opening tip end of the cylinder, the suction force is particularly strong. Since the collected foreign matters are enclosed in a storage box, it is no need to pull out and bring a hose and it makes the tool easy to use. The collected foreign matters are easily discarded.
