Roomba i7 Vs. S9: Which is better?
If I were to choose, I would suggest investing in the iRobot Roomba S9. The only advantage iRobot Roomba i7 has over S9 is the price, but it is still quite expensive itself. The S9 Roomba has 30% wider brushes, a special D-shape which makes it easier to clean in certain areas, and 30 times higher suction power, significant improvements that are nice to have.
S9 gives 99% cleaning efficiency. In practical experiments, S9 has proven to be better in performance in corners. The suction power is 30 times more in Roomba S9 as compared to i7, which means better performance.

But for people who live in a smaller home and don’t need as much suction power, the i7 is just as good a deal while saving you a lot of money.
