Difficult to say. I find the j7 Combo very suitable for everyday use. I am satisfied with the mopping performance. In addition, there is only one device in the flat. Since I got it, I don't use the Braava Jet anymore.
Hello Luana.randazzo.lr The Braava jet m6 specialises in mopping, which gives it maximum cleaning power. No 2-in-1 robot can do that, neither an iRobot, nor any other. The Roomba Combo j7/j7+, on the other hand, has the advantage of being able to do both vacuuming and mopping. It depends on what is more important to you. If you like having a machine that can do both and performs very well at both, then choose the Roomba Combo j7/j7+. However, if you want the best mopping performance, then go for the Braava jet m6. We hope we answered your question. Your iRobot Team
I had also wondered about this before I bought it, as iRobot also offers two devices for each type of cleaning. However, I am completely satisfied with the cleaning performance of vacuuming and mopping.
