A portable vacuum cleaner for attaching to a can of compressed gas having an output for creating a suction. The cleaner includes a body, a nozzle attached to one end of the body, and a receptacle attached to the other end of the body. The body includes a cap for attaching to the can of compressed gas, and which has a throughbore. The body further includes an external tube that has an intermediate portion, a forward portion, and a rear portion. The receptacle includes a tube and an air permeable bag. The body further includes an internal tube, a valve, and a trigger, which when pressed, opens the valve which allows compressed gas in the can of compressed gas to exit through its output and flow through the internal tube into the rear portion of the external tube and thereby create a suction in the external tube which causes dirt to be drawn through the nozzle, through the external tube, through the tube of the receptacle, and be captured in the air permeable bag. The nozzle is hollow and can be either cylindrically-shaped, conically-frustrum-shaped, or include a proximal portion, an intermediate portion forming a sump, a distal portion forming a trap, and a web to add rigidity to the nozzle as a result of its general serpentine shape, with the sump capturing any liquid passing therethrough, and with the trap maintaining the liquid in the sump.
