The iRobot Roomba 621 is designed to provide automated floor cleaning. It features a patented 3-Stage Cleaning System that loosens, lifts, and suctions dirt, dust, and debris from both carpets and hard floors. Integrated Dirt Detect™ sensors enable the robot to focus on areas with higher concentrations of dirt for a more thorough clean. The robot is equipped with Dual Multi-Surface Brushes that adapt to different floor types, and an Edge-Sweeping brush for cleaning along walls and in corners. It operates for up to 90 minutes before automatically returning to its Home Base to recharge.
