It quietly goes about its way 
While the NaviBot is vacuuming, you can chat on the phone, read a book or watch television programme in the same room! The NaviBot features Samsung’s Air Path Technology, which reduces irritating noise and makes it one of the quietest vacuum cleaners around. It’s so quiet, you may find yourself looking up to see if it’s still on. 

Knows where to clean and where not to
Virtual Guard™ gives you two convenient options to protect your space. By pressing just one button, you can activate the Virtual Fence that prevents NaviBot from entering areas where you might have valuable furniture, a pets’ bed or anything else you want the NaviBot to steer clear of. Or you can choose Virtual Guide mode. It cleans your living room and then moves onto the next room—and then the next room after that—all according to your designated order.
