I don’t know what it says about humanity that we keep making robots with the express purpose of cleaning something. Anyway, here’s one more, the Magnetic Automatic Aquarium Glass Cleaner, the robot that cleans the sides of aquariums.

This little robot clings to the walls of the aquarium and cleans the glass so that you can enjoy the view of your fish. It prevents the build up of algae. Much like a roomba, it runs until it’s out of juice and then docs itself so that it can charge and keep the party going.

It’s compatible with a number of fish tanks and once set can be left to it’s own devices. For those who don’t have those little snails or other waste eating fish and don’t want to be bothered with the work of keeping an aquarium, you can get this for $159.99.
