<p>A multi-purpose attachment tool for a hand-held vacuum cleaner combines the functionality of both a crevice tool and an extension wand in a single instrument. The multi-purpose attachment tool for a hand-held vacuum cleaner includes an insertion end adapted for friction-fit slidable mounting into the nozzle end of the hand-held vacuum cleaner, a nozzle end adapted for cleaning crevices and the like, and a self-supporting accordion-joint interconnecting the two ends. The self-supporting accordion-joint, preferably an annular bellows, is both axially extendable and bendable off-axis. When it is in its axially collapsed condition, the multi-purpose attachment tool serves as a crevice tool, but when it is axially extended, or axially extended and bent off-axis, the multi-purpose attachment tool serves as a crevice tool and/or an extension wand depending on the cleaning application.</p> |
