Roomba Diffusion Lens

**WARNING!** This will void your Roomba warranty, *and turn it into a kamikaze death machine*. **Don't use this** if you have cliffs (stairs, ledges, actual cliffs) where it cleans. Your Roomba might also go places it couldn't go before, and will be a new source of wear and tear for whatever it bumps into.

Created to defeat overzealous cliff sensors, which caused my Roomba to shut off any time it brushed up against a rug. This is a common problem with cleaning robots and dark or thick rugs.
