Roborock Vs. Roomba: 2 impressive robot-vacuum mop combinations compared

It used to be impressive for robots just to vacuum floors automatically, but now more sophisticated machines offer both vacuuming and mop features. Other companies sell systems that combine two discrete robots, one designed for vacuuming and another built for wet mopping.

This post looks at two solutions sold by different manufacturers. Each has a unique approach to floor care in the home. Which is the best choice? Read on to find out.


The original pioneer in the robot vacuum cleaner, iRobot was also the first to offer an autonomous mop. Its latest floor scrubber, the Braava Jet M6, wipes the hard floor of your home on command. And when paired with iRobot’s most sophisticated vacuum cleaner, Roomba J7 Plus, both machines form a tag-team cleaning duo.

When the vacuuming is done, it will instruct Braava to start mopping. Both devices also share the floor plan of your home, so they will be able to effectively navigate across floors and through spaces with accuracy.

Roborock S7 MaxV Ultra

One robot for total floor care


Roborock was founded in 2014 and is a relative newcomer to the robot vacuum cleaner scene. Nevertheless, the company offers many advanced floor cleaning products. Most notable is the upcoming S7 MaxV Ultra. This device, which is expected to arrive in stores in the second quarter of 2022, combines a vacuum and a mop into one robot. Roborock even says that Ultra performs its own maintenance so you can clean up without getting your hands dirty.

Although I have not spent time with the Roborock S7 MaxV Ultra, CNET has put the regular Roborock S7 through a battery of lab-based experiments, and the newer system is built around an identical S7 device. This means that it is likely to deliver results similar to the S7 robot we previously used. If so, then the S7 MaxV Ultra should generally be a better vacuum than the Roomba J7 Plus.

S7 was able to remove more sand across all three of our test surfaces (67% low-carpet, 84% hardwood, 65% medium-carpet). By comparison, Roomba J7’s figures were a mixed bag (60% low-carpeted, 92% hardwood, 17% medium-carpeted).

When it comes to pet hair, the S7 was once again the clear winner. It completely removed all traces of scales from hardwood, with only a few tufts left on medium and low-pile carpets. Conversely, J7 extracted only 50% of its hair from hardwood. That said, it was an easy task for Roomba to pull pet hair from blankets.

Both machines navigated CNET’s test room with efficiency and speed. However, the S7 beat the Roomba J7’s execution time by 1 minute (16 minutes compared to 17 minutes).

Winner: Probably Roborock S7 MaxV Ultra

Some robotic vacuum cleaners like Samsung Jet Bot AI Plus are billed to avoid pet feces but encounter problems in the lab.

Roborock also says that the S7 MaxV will be able to recognize and avoid solid pet waste, the same trick we have already seen successfully implemented in the Roomba J7. That said, I have not tested this on the S7 or S7 MaxV Ultra. Another company, Samsung, made similar claims, but unfortunately its Jet Bot AI Plus could not work as advertised, so I will have to test Roborock’s navigation estimates for myself before I can give full credit here.

Winner: Draw

Self-cleaning abilities

This is the area where the Roborock S7 MaxV could win an undisputed victory. Both robots have base stations that empty each vacuum cleaner’s trash can when full. Both systems can also dry hard floors as part of the cleaning process.

However, the S7 MaxV raises the bar, at least in theory. According to Roborock, the “Ultra” base station not only fills the robot’s water reservoir, but it also automatically cleans the S7’s mop pad. If this feature fails, it will be a game-changer.

Winner: Roborock S7 MaxV Ultra (at least on paper)

Price and value

The Roborock S7 MaxV Ultra sounds like a phenomenal machine. With a sticker price of $ 1,400, it’s not cheap. Of course, iRobots solution is not for penny pinchers either. Adding the price of the $ 850 Roomba J7 Plus and $ 550 Braava Jet M6 sets you back just as much ($ 1,400). And since the S7 does more for the same dizzying pile of cash, my money’s on Roborock. After all, if I spend so much on both, I would rather have the more skilled system.

Winner: Roborock S7 MaxV Ultra

As it stands at the moment, the S7 MaxV Ultra seems to hold all the cards. This floor-cleaning match score of 2 to 1 in favor of Roborock seems to be crucial. That said, it’s more of a paper win, and it depends on whether the S7 MaxV delivers similar performance as the standard Roborock S7. Time will tell on that front.

The same goes for the machine’s promised pet shade and automatic mop cleaning capabilities. So even though the result looks unique right now, we do not know for sure until CNET is able to put Roborock’s fancy new robot through its paces. Keep an eye on it.
