Made by iRobot, this is Roomba 960, the robotic vacuum that you can command to clean from anywhere via a smartphone app. The free app for Android or iPhone lets you start, pause, and monitor Roomba 960, set a cleaning schedule, and even track job history wherever you are—or you can simply press the “clean” button on the robot. You can also start, stop, or dock your Roomba through voice commands using an existing Amazon Alexa or Google Assistant device. Roomba 960 uses advanced software along with optical and audio sensors to thoroughly clean rooms from edge to edge, detecting areas that require concentrated cleaning while avoiding furniture and stairs. Ideal for pet owners and allergy sufferers, Roomba 960 forgoes typical vacuum brushes for two rubber rollers that break down debris while a powerful vacuum deposits dirt, dust, hair, and allergens into a HEPA-filtered bin. Roomba 960 runs continuously for up to 1 1/4 hours and automatically recharges itself and resumes cleaning until the job is complete. One included dual-mode Virtual Wall Barrier confines Roomba 960 to a room until it is cleaned or creates a protective zone around an area you don’t want it to enter. Includes extra filter and four AA batteries for Virtual Wall. App requires WiFi network. 14" Diam. x 3 3/4" H. (8 1/2 lbs.)
