iRobot Roomba Combo J7 Plus vs. Roborock S7 MaxV Ultra: Which Robot Vac and Mop Is Best? - CNET
Thinking of spending big on a high-end robotic floor cleaner that vacs, mops and empties its own bin? Here's how two of your top options compare.

Robot vacuums have made some mighty impressive strides over the last decade or so. Shop around, and you'll find a wide variety of models that all offer app and voice controls, self-emptying bins, built-in mopping functionality and more.
If you want an all-of-the-above kind of cleaner for your home, then you'll need to be willing to spend up, because all-inclusive automated floor cleaners don't come cheap. Two of your top options are the iRobot Roomba Combo J7 Plus and the Roborock S7 MaxV Ultra. Holiday sale pricing aside, both typically cost well over $1,000 at retail, and they're each about as fully equipped as robo vacs currently get, with bins that automatically empty into the dock after each run, optional mopping capabilities for homes with hardwood or tile flooring, and smart home integrations with Alexa, Google and more. Both brands are also stronger-than-average performers in our exhaustive cleaning tests.
So which one is the better splurge? It's a good question, and there's a lot to consider, so let's get right to it, starting with the key specs that set these two floor bots apart. (You can also check out our picks for the best robot vacuums overall.)
