How Does Robot Roomba Work?
Roomba is an intelligent, effective and automatic vacuuming robot. It can clean the whole floor, avoiding stairs, steps and objects on the floor by emitting an infrared signal. It can clean efficiently under furniture, along the edges of walls, and around objects. It also detects the dirtier areas of the floor with its sensors. When programmed with a ‘Virtual Wall’, it will go where you want it to clean. At the end of the cleaning, it looks for the signal emitted by its ‘home base’ and returns to recharge and to wait for its next clean. When the battery runs low, it will also return to the recharge point. This answer could do with a little bit more technical detail. It doesn’t effectively answer the question.
