At the touch of a button, bObi by bObsweep assumes responsibility for keeping your hardwood and tiled floors free of dust, dirt, and pet hair, even when you're away. The programmable robot vacuum thoroughly cleans floors with a multi-step process—first sweeping and vacuuming with its dual main brushes, then mopping and sanitizing using its built-in UV light. The vacuum employs 80 sensors to maneuver through homes without jostling furniture, but you can also dictate its movements with a radio-frequency omni-directional remote that works even when you don't have a clear line of sight, such as through a wall. As bObi cleans up, built-in HEPA filtration keeps dust particles locked inside the washable dustbin, where they can't aggravate allergies or foment rebellion among dust bunny tribes. http://www.groupon.com/deals/gg-robot-vacuum-cleaner-and-mop-bobi-by-bobsweep-0.
