Roomba Combo j9+ review: The ideal robot vacuum and mop

The Roomba Combo j9+ is the ideal robotic vacuum and mop. It can easily suck up dirt while also wiping down your floors, and now it’s smart enough to refill its own water tank.

In 2020, MIT Technology Review reported that development versions of the Roomba J7 captured images of a woman sitting on a toilet and a child playing on the floor, which made their way to a library used by the labeling service Scale AI. Even when iRobot is running a sale (we've seen it drop the price down to $999), the Combo j9+ is pretty pricey, but that cut does make the j9+ more palatable for longtime Roomba owners who've learned how to fit the bot into their cleaning routines. iRobot isn't completely out of line with its pricing: The competing Roborock S7 Max Ultra offers similar vacuum and mopping features and typically sells for $1,299(it's also on sale for $999 at the moment).
