An improved bag docking assembly for aligning a vacuum bag for engagement with a dirty air outlet nozzle on a vacuum cleaner, and for retaining the vacuum bag in the position of engagement. The column function is capable of performing an operation on an indeterminate number of entries. 01% and is positioned vertically on the substrate; source and drain regions formed in the semi-conducting material of the fin; a gate dielectric layer overlying the fin; and a gate electrode wrapping around the fin on the top surface and the two sidewall surfaces of the fin overlying the gate dielectric layer. A pressure chamber may be provided surrounding the tube to supply the jets.
