Powerful pick up and powerful performance. Pulls in stubborn dirt and messes with a Premium 3-Stage Cleaning System and 10X the Power-Lifting Suction.* Control how you clean with the iRobot HOME app or your voice assistant. Smart navigation gets the job done. The i3 navigates and maps your home in neat rows using state-of-the-art floor tracking sensors to vacuum hardwood and carpet. Goes where it's needed, avoids where it's not. Reactive Sensor Technology tells the robot where it can and cannot reach, which means less getting stuck on furniture and more knowing where to go. And with Dirt Detect™ sensors, it can focus cleaning where it’s needed most, like the dirtiest areas of your home. Learns your life, listens to your voice. Learns your cleaning habits to offer up personalized schedules, while Google Assistant and Alexa allow you to start cleaning with just the sound of your voice. The i3 will even suggest an extra clean when your area’s pollen count is high or during pet shedding season. Ideal for homes with pets. Unique Dual Multi-Surface Rubber Brushes don't get tangled with pet hair. Brushes adjust and flex to stay in constant contact with carpets and hard floors. High-Efficiency Filter traps 99% of cat and dog dander allergens. *Works with Google Home and Alexa enabled devices Alexa and all related logos are trademarks of Amazon.com or its affiliates.
