First, let me say this is a fantastic forum. I've learned so much. I will admit, though, that I've been confused by contradictory posts about the level of difficulty in cleaning the Vent-a-Hood. I've been inclined to get one for my kitchen, but now I'm uncertain. Are certain models of Vent-a-Hood range hoods easier to clean than others? Did they recently redesign their hoods so people are comparing different designs?
