The Roomba i3+ comes equipped with the Clean Base® Automatic Dirt Disposal. With Clean Base Automatic Dirt Disposal, the robot empties debris on its own, with no intervention from the user. Consumers don’t have to think about emptying the bin for months at a time or worrying the robot won’t finish the job due to a full bin. The Roomba i3+ automatically empties up to 60 days’ worth of dirt and debris into the Clean Base, which doubles as the robot’s charging station. The debris is then locked away in the Clean Base’s enclosed AllergenLock™ bag that uses four layers of allergen blocking material to trap 99 percent of pollen and mould.
