Panasonic recently devised a new form factor for a floor-cleaning robot: Rather than a wheeled disc, this one crawls around on the floor like an inchworm, picking up dirt with its "super-absorbent nanofiber cloth" skin.

Called the Fukitorimushi, or "wipe-up bug," the device provides feedback by activating a Cylon-like red light when it detects dirt, so you know when it's working. Because otherwise, as you can see in this video, it's not very clear it's doing anything at all.
