This vacuum is so smart it could start its own Mensa chapter. The suction adjusts itself depending on the type of flooring, and automatic shutdown prevents overheating. A silent setting offers quiet operation, and an extra-long cord means less outlet switching. Makes you want to clean house. Almost.
