Even in that demo cube, the spray is lethargic. I can't help but wonder if these are some of the "HE" dishwashers that have given modern machines such a terrible reputation. My new Whirlpool uses a third of the water shown in the videos, has a tiny pump, and yet has torrents of water spraying from its arms. I frequently have light plastic cups and containers being flipped on the top rack, and I thought that with this machine I wouldn't have to worry about glass bowls clinking on the bottom rack like I used to have in the PC and Voyager, but I still have to stop and rearrange because of it in this new machine. I still have yet to have any issue with leftover soils or a dirty filter, and still have no grime buildup or smells at all, and that's with primarily using the Normal cycle.
