"So; anyone have a mini-vac they love?"
Yeah, but it's not helpful for you. I got a 110V hand vac about ten years ago from Home Depot which was absolutely terrific --easy to take apart, easy to clean the filter, had a nice 15ft cord, and a really great suction.
About a year later I decided I needed a new filter, Home Depot no longer carried this gem and had no suggestions as to where to get a new filter. Instructions (Chinese Product) had no reference to pursue.
Still using it, still washing out the filter, about to rebuild a new filter from other filters.
Ticked me off that there was no way to contact the manufacturer, even to give them a compliment.
Told you this wouldn't be helpful.
