Ok, so am I the only one that thinks this thing would just dominate snails on the glass, corals that may be too close to the glass or bump rock piles that are too close to the glass and maybe cause a rock slide?

I love the idea, but is it safe from all these applications?

I SOOO want one!!!

If its like the automatic house vacume, you set up laser parimeters of where you want it to clean too with laser boundaries.

Oooor im guessing it has a light sensor or something that can read off the reflection of the substrate or corners of the tank.
