I had been using the Roomba J7+ for the longest, it was a combo as well. This RoboRock is absolutely phenomenal, the app is so much more user friendly and the robot itself is great. It cleans my floors very well, it’s super simple to empty the dirty mop water and refill the fresh clean water. The app tells you when it’s getting close to time for replacing the brush & roller and mop pads. I have it set on a schedule to mop & vacuum my floors every night at 11:45 that way the floors are nice & clean when we wake up. It’s also super quiet when it’s emptying the vacuum bin and we do not even notice it. I would absolutely recommend this product to anyone in the market for something like this. If you have kids & dogs like me and easily get tired of constantly having to sweep and mop the floors, just do yourself a favor and get this product. You are able to see my shiny clean floors in the photo provided!

Works great and is vey quite. Have had no issues and easy to use.
