Seems the little Roomba/Scooba guys aren’t as efficient as we think they are. The way they work, see, is by tracing random paths along your living room, until they’ve supposedly covered everything. Problem is, seems they can miss spots and wont really know it.
Well, if you buy a special carpet, and a special vacuum from companies Vorwerk in Hamlin, and Infineon in Munich, Germany, new technology will ensure that every little dust speck has been properly sucked away. The carpet is embedded with RFID chips, and the bot uses this information to know exactly where it’s been. If it misses a spot, for whatever reason (say, the baby got in the way), it will know this and come back to it later.
Seems nifty enough. Check it out at the Discovery Channel. Story VIA Gizmonews.
