Not terribly heavy. It was a Hilti DD-WMS100 water management vacuum for core drilling. Maybe a little heavier than a typical large shop vac. I delivered it to Hilti for warranty repair, they sent it to their warranty repair center and this is how I got it back days later. It was packaged well by Hilti from what I can tell. But it looked like the box fell off the truck and rolled down the freeway.
