Have a nice day
Thank you for your question. Rafael's answer is correct. We have the i7 model with charging station, where you have to empty the bin yourself. Otherwise, there is the Roomba i7+ with suction station (charging station included). Here:
iRobot Roomba i7+Here, the dirt container of your Roomba empties itself after each cleaning. So you don't have to empty the bin yourself. This vacuum station can also be purchased at a later date.
If you have any further questions or uncertainties, we will be happy to help you.
Best regards,
Your iRobot team
