I believe the only difference is the collection base that you get with the s9+. Otherwise the robot itself is the same for both models. Personally I don't understand why anyone would get the robot without the collection base.
Dear Customer Thanks for your request The bags in the clean base are not design to hold liquids as this is a dry surface vacuum robot The bags are design to hold the dirt and to help you forget about vacuuming for months at a time. The system allows the s9+ to empty itself for up to 60 days. With the Anti-Allergen System, 99% of pollen and mold allergens are trapped from the robot to the base so they can't escape back into the air. I hope this helps and feel free to visit www.iRobot.com for more information Stay safe iRobot
