ABSTRACT:
A portable vacuum cleaner attachment, that can be attached to the end of a vacuum hose to remove and separate fluid, so that the fluid does not enter the vacuum unit. The attachment has a housing with an outlet that can be coupled to the vacuum hose, and an inlet that can engage a working surface to remove the fluid with an airstream created by the vacuum unit. Attached to the housing is a tank that stores the fluid as it is removed from the working surface. Within the tank is a first passage that provides communication between the housing inlet and the tank, and a second passage that provides communication from the tank to the housing outlet. Located in front of the first passage is a wall that deflects the fluid down into the tank, while the air flows into the second passage.
