ABSTRACT:
A portable attachment for tank-type vacuum cleaners is provided which permits pickup of liquids as well as solids with the aspirated air. The attachment comprises a portable container having a removable cover thereon which makes a substantially air-tight connection with the container. A pair of nozzles are provided on the cover for fluid flow communication between the inside and outside of the container. One of the nozzles is adapted to have the suction hose of a tank-type vacuum attached thereto, while a scavenger hose for conveying a mixture of air, dirt particles, and liquid to the container is attached to the other nozzle. Valve means in combination with the first nozzle is spring biased in the closed position so that fluid flow communication between the inside of the container and the suction hose of the vacuum cleaner is established only when the valve means is activated to its open position.
