This product has a very Japanese feel to it. It's exactly the sort of random gadget they love.
The main functionality is to detect movement in its vicinity, and then when the movement has stopped it pouts out a small amount of ozone enriched air to combat odours.
Aside from its advertised use for a cat litter tray, it would also have uses in other areas like a fridge or cupboard where the opening of the door and other activity would trigger a burst of air sterilisation.
The ozone is created by the action of an electrical corona discharge, which splits air molecules apart into their separate atoms temporarily, allowing them to recombine in active forms like ozone (three atom oxygen) which is unstable and donates its third oxygen atom to anything in the vicinity, oxidising it in the process. That could be an odour molecule, fungal spore, virus or bacteria. The oxidation has the effect of disrupting things at a molecular level, reducing odours and damaging spores, viruses and bacteria.
It's an odd, but neat unit. For the technically inclined, it's useful to clean the little ozone generator from time to time or best performance. I tested the unit for a while, so the pattern on the ozone ring was caused by the strong oxidising effect concentrated in that area.

This also keeps the channel independent of KZfaq's algorithm quirks, allowing it to be a bit more dangerous and naughty.
