dishwasher trolley

Recently I have been having thoughts about making dishwashers easier to empty - not that dishwashers are hard to empty, but the problem, if you are old, is that you cannot carry as much and so, if the dishwasher is full, to unload it you have to make several trips.  Then of course the problem is that if you are old, you do not want to make several trips.  Why not make a small dishwasher with the baskets on a trolley, so that you can wheel all the items around your kitchen to unload them.
