The Roomba i7+ comes with what iRobot calls the Clean Base Automatic Dirt Disposal. To put it succinctly, it is a storage unit that vacuums out the contents of Roomba and stores it within an enclosed bag. The system ensures that accumulated dirt and dust isn't recirculated back into the air when the Roomba is emptied. Once the Clean Base bag is full, users will be notified by an in-app notification on their smartphone.
iRobot says that the Clean Base can hold "30 bins" worth of dirt and other debris, so that should be good for at least a few weeks of automatic cleaning without needing user intervention.
The Roomba i7+ also adds a new layer to the room-mapping feature that's available in the Roomba 900 series of robotic vacuums. The vacuum can create a map of every room in your house (it can store up to 10 floor plans) so that it can plot its cleaning path. Using iAdapt 3.0 Navigation with vSLAM, the Roomba i7+ will then recognize whatever room you place it in and automatically clean the floors using the most optimal roving pattern.
Sorry, just could not resist...
As you might expect from such a feature-packed Roomba, it also includes Google Assistant and Amazon Alexa integration. As a result, you can ask either AI voice assistant to "Clean the living room" or "Clean the kitchen" and it will wake up and go to work, returning to its Clean Base when the job is done (and of course, it's dust bin is then automatically emptied).
The iRobot Roomba i7+ and its accompanying Clean Base will retail for $949 when it launches early next year. You will also be able to buy a three-pack of replacement bags for $14.99 each.
