An attachment assembly for a wet/dry vacuum comprising first and second tubular structures with a third tubular structure spanning a junction between the first and second tubular structures. The third tubular structure may be resilient to conform to both the first and second tubular structures. In a first position, the third tubular structure may span the junction between the first and second tubular structures and, in a second position, the third tubular structure may be rolled back onto itself to engage only one of the first and second tubular structures. The third tubular structure may resist separation of the first tubular structure from the second tubular structure in the first position. The third tubular structure may also seal the junction between the first and second tubular structures.
