The Neato BotVac D75 Robot Vacuum Cleaner has a patented laser-guided technology scans and maps the room, plans, and methodically cleans, automatically moving from room to room. 50% larger brush, bigger-is-better dirt bin, extra large filter, and precise edge cleaning brush pick up more dirt and debris. Schedule daily cleanings or push a button for instant multi-room or spot cleaning. Automatically goes back to charge base, then returns to where it left off. Features: Advanced SpinFlow Power Clean system picks up more of the stuff that lands on the floor--like dirt, cereal, dustbunnies, and crumbs. 50% larger brush gets closer to the wall than those round robot vacuums.
