Mini Robot Cleaner
While this obviously isn't R2D2, it still looks very cool, what with its R2D2 like shape, and flailing waving arms (R2D2 didn't have those). Fortunately, it's more than just a toy as it also is a mini vacuum cleaner of sorts, and cleans up dirt and dust. Once the button on top is pressed, this little robo-maid will glide across the desk sucking up dust and crumbs alike. This robot cleaner is available for $14.99, and comes in 3 colors.
