I can see how this could, theoretically, help manage spills and related injuries. However, at least the one near me is so slow. It would take hours for it to do a round of the store. It spends most it's time standing still in an attempt to not get in the way of passing shoppers. I'd think that having a stock clerk make a round of the store every 45 or hour would work much better. A brisk walk across the top of the aisles, looking down them for spills, wouldn't take more than a few minutes.
