Nice job on cleaning the droid! I admire those who care for their machinery. I just finished giving all three of my 315 robots a full spa treatment. Since I have sealed all of the holes in the case I am able to wash them down easily with hose and brush. Just to be sure there was no leakage I opened them up to inspect. Not a drop, and I placed a desiccant pouch in them to keep the interior ultra dry. It has been 6 months since I sealed all the openings, and the results have been perfect. I was never happy in the past to find all the dirt, grass and moisture and bugs in the blade motor compartment and some in the case with the main boards etc, and I prefer for the case to be perfectly clean when I open them up for inspection and repair. I live in Florida where it is very humid and lots of ants and spiders trying to get inside everything. Now the robots are protected. Thanks for the inspiring picture!
