Verdict

The iRobot Roomba 971 is a smart robot vacuum weighing 3.91 kg and measuring 9.1 cm in height, equipped with a 0.6-liter dustbin and powered by a 33W Gen 2 motor that delivers 5x the suction power of older 600-series models. Its main characteristics include vSLAM camera-based mapping, a 3-stage cleaning system with dual multi-surface rubber brushes ideal for pet hair, and a lithium-ion battery providing a 75-minute runtime with auto-recharge and resume capabilities. Key pros are its relatively quiet 58 dB operation, efficient row-by-row navigation, and smart app and voice control integration via Alexa and Google Assistant; however, notable cons include a long 3-hour charge time, a lack of hardware-defined no-go zones or physical virtual walls, and the absence of a self-emptying base.
