The Roborock S6 is worlds better than iRobot in every way thus its a no brainer. Besides saving lots of money you will own a reliable robot that will clean your house every single day without any complaints. My Roborock is set to daily clean since over a year and has never failed once. Cheers

I have this Roborock S6 and I never use the mopping function. If the floor happens to be dirtier, it will lubricate more than it cleans.

I had the same thought before I purchase Roborock. The mopping function is a very simple yet efficient mechanism in Roborock S6, so I wouldn't worry about if it's not that durable( you will know what I mean when you get one on your own;) ). I would recommend you to give it a try. I am very happy that I chose to try with this one first.
