To add to Nyllons solution you don't actually have to reload after getting 25 you can comfortably get over 50 items in that room. Load up Act II Adventure mode (unlocked after beating the story) and travel to the lower bounty City of Caldeum, now follow the route in the video to get over 50 items in one go. I used the Monks sweeping wind ability to help it along but its not necessary rolling through the objects works just as well and I've done it on numerous occasions.
