They’d hate to overwork their hamsters, but then again sometimes those little critters ought to *earn* their keep instead of being cared for all the time. Here’s a Roomba that has been retrofitted with a special mechanism that enables it to be controlled from the hamster ball. In essence, the Roomba will go wherever the hamster runs, but chances are your floors will be cleaned in random zig zag lines and not in an orderly manner, making this cute little project more of an interesting experiment instead of a practical solution.
