I owned 3 Mighty Mites over the last 2+ decades.  Loved all 3.  The last one worked great for about a decade.  I use it in my service business as both a hose vac and in seconds could switch the hose around to the back side for a powerful blower to dislodge dust that a vacuum attachment would never find.  With the thin attachment on the end of the hose, the blow power was just short of an air compressor.
