Features a combo brush that is uniquely designed to pick up pet hair-and is quieter, too, especially on hard floors like wood and tile. 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.
