iRobot Roomba i4 EVO Wi-Fi Connected Robot Vacuum

The iRobot Roomba i4 EVO is a Wi-Fi connected robot vacuum that handles floor cleaning on its own. Its 3-Stage Cleaning System delivers 10X the suction power of the Roomba 600 series, pulling dirt, dust, pollen, and pet hair from carpets and hard floors. Dual multi-surface rubber brushes flex to different floor types and resist tangling with pet hair. Dirt Detect Technology spots dirtier areas and focuses cleaning there. Smart mapping is a key feature. The vacuum learns your home's layout and cleaning habits, so you can direct it to specific rooms via the app or voice commands through Alexa, Google Assistant, or Siri. It cleans in straight lines, returns to its base when the battery runs low, and resumes where it left off. The battery is 20% larger than other Roomba i series models, extending runtime for whole-home sessions. It works well on hardwood, tile, and low-to-medium pile carpets. At 7.05 lb, it fits under most furniture. The vacuum does require occasional maintenance and works best when floors are cleared of large items first. Navigation is the weak spot on some units: it can get lost, fail to find its base, or lose its way when furniture or clutter moves.
