Handheld canister vacuum cleaner

A handheld canister vacuum cleaner device includes a canister assembly with a canister having a hollow interior and a suction-producing subassembly mounted on the canister that sucks air from the hollow interior. An attachment-coupling component is provided on the canister that serves to hold a vacuuming attachment on the canister while coupling the vacuuming attachment in fluid communication with the hollow interior of the canister. The attachment-coupling component holds the vacuuming attachment pivotally so that a user can pivot the vacuuming attachment relative to the canister to multiple user-selected angles for operating convenience. Preferably, the attachment-coupling component includes a ball-and-socket arrangement that includes a ball-shaped portion of the attachment-coupling component held pivotally by a socket-shaped component on the canister so that the user can pivot the attachment-coupling component to and lock it in place at a desired one of multiple pivotal positions.
