The units in this sale are being sold as open box condition. That means that they have been opened due to being a photo sample, a tested good customer return or having damaged packaging. Some non-essential items may be missing from the box. The unit may not be shipped in retail packaging. That is the reason for the reduced sale price and the reduced warranty.

From the moment you press "clean," the iRobot Roomba 850 robotic vacuum goes to work, sliding under and around furniture to pick dust and dirt while you kick back and relax. With a full suite of iAdapt sensors, it learns the layout of your home and dodges beds, curtains, and stairs as it goes. And thanks to a three-stage AeroForce cleaning system with AeroForce extractors, it delivers quality cleaning power. 

• Cleans all floor types - The Auto-Adjust cleaning head automatically adapts its height to keep the Multi-Surface Brushes in close contact with different floor surfaces, effectively cleaning carpets and hard floors
• Patented Aero Force 3-Stage Cleaning System uses Tangle-free Multi-Surface Brushes and Power-Lifting Suction with 5x the air power to pull in embedded dirt, debris, and pet hair from wherever it hides (compared to Roomba 600 & 700 series robots)
• Tangle-free Dual Multi-Surface Brushes handle pet hair with ease; high-efficiency filter captures allergens, pollen, and particles as small as 10 microns
• Full suite of intelligent sensors guide the robot under and around furniture to help thoroughly clean all your floors
• Includes: Roomba 850 robot, dock, remote control, and a rechargeable NiMH battery
• Vacuum dimensions: 14 x 14 x 3.6 inches
