It's the future of housework! Program the Roomba to clean when it's most convenient, and then leave confident that it will do a thorough job. This technological wonder systematically cleans four rooms on a single charge, getting into hard-to-reach areas while avoiding drop-offs and adjusting for carpets or hard floors. The virtual wall lighthouses confine the Roomba to one room until the entire floor is vacuumed, while it detects dirtier areas and spends more time on them. Featuring innovations for improved performance and durability, this vacuum simply must be seen to be believed.
