ABSTRACT:
A vacuum cleaner having a substantially cylindrical tank with a bottom, a cover which pneumatically closes the tank to define a vacuum chamber, an eccentric inlet and an outlet through the tank cover which define a pneumatic path through the chamber and a vacuum source for causing air flow along the path from a dry to a wet filter vacuum cleaner. A convex baffle, in the shape of an inverted shallow bowl with a rim of diameter somewhat less than the diameter of the tank is adapted to be approximately concentrically mounted in the tank above its bottom and has an eccentric aperture which is vertically aligned with the inlet when the baffle is properly situated in the tank. A tube is adapted at its upper end to be connected to the inlet and extend downwardly, snugly through the aperture. The lower face of the tube is cut at an angle other than 90.degree. and optimally at approximately 45.degree.. The lower face of the tube lies between the rim of the baffle and the bottom of the tank and faces substantially toward the center of the baffle. When the baffle and tube are properly mounted in the vacuum cleaner and the tank is filled with liquid to a level above the face of the tube and below the rim of the baffle.
