The Beauto DIY Roomba Kit (Japanese translation, please improve it?) gives you the chance to play all rocket scientist and create your own robotic vacuum cleaner. Do please note that the fact it runs off 4 AA batteries may not bode well for its clean time or efficiency. Nor for your wallet if you have to keep buying new Duracells. $156.00 or so in Yen like.
