4 stars: My only issue is that I can't map my area and label each room. I've followed the directions on iRobots website, I've made sure the app is up to date, even deleted it and redownloaded. Still can't. Apparently this is a relatively common issue
5 stars: Absolutely love it. Debated over the I7 or S9. I went with the cheaper option and it is fantastic. I think the S9 is a bit faster and they say it is better along walls but I can't imagine what would make it worth the extra cash. The I7 is awesome
4 stars: love my Roomba! although there appears to be a glitch some times when it finishes a job, the status says \
5 stars: There are some things I'd like it to be able to do, but, for how it's set up for its current capabilities, it's amazing. I love this thing, and the app is great. Already proven to be more useful around the house than anything else I own!
5 stars: Great.. the software is robust and easy to use and is the major reason why irobot vacuums are a good value... 27 hours on the i8 irobot now and no issues...
3 stars: Cleans great but often gets stuck on small carpets and gets lost when doing entire first floor even if my house is not huge but still cool.
5 stars: Great tool to see and measure results. Easy to use and intuitive.
4 stars: They don't make it compatible with older phones (even same android version). Had issues in the past with a one plus 5 and the only way to make it work was getting a newer phone. By looking at the reviews...
