I did something really really really stupid today. I was inspecting one of my other lesser vacuums in close proximity to the Sentria II, and Old Man Murphy showed up. The lesser vacuum made a nice huge scratch right on the front of the Sentria II. I don't really see how it could possibly happen, let alone be as deep as it is. Makes me absolutely sick that this happened. I won't show it picture, it's just to disconcerting to look at.
