Roborock vs. Roomba: 2 impressive robot vacuum mop combos compared

It used to be impressive for robots to vacuum floors only automatically, but now, more sophisticated machines offer both vacuuming and mopping functions. Other companies sell systems that combine two separate robots, one designed for vacuuming and the other for wet wiping.

This post looks at two solutions sold by different manufacturers. Each home takes a unique approach to floor care. Which is the better option? Read on to find out.

Vacuuming Power and Efficiency

While I haven’t spent time with the Roborock S7 MaxV Ultra, Nerdshala put the regular Roborock S7 through a battery of lab-based tests, and the new system is built around a similar S7 unit. This means that it will probably produce similar results to the S7 robot we have used before. If that’s the case, the S7 MaxV Ultra should be a better vacuum than the Roomba J7 Plus.


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

When it comes to pet hair, the S7 was once again the clear winner. It completely removed all traces of dander from hardwood, leaving only a few tufts of dander on medium- and low-pile carpets. In contrast, the J7 only removed 50% of the hairs from the hardwoods. That said, pulling pet hair from carpets was an easy task for the Roomba.

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

Winner: Likely to be Roborock S7 MaxV Ultra

Some robot vacuums, such as the Samsung Jet Bot AI Plus, are billed to avoid pet poop but run into problems in the lab.

Roborock also says the S7 MaxV will be able to detect and avoid solid pet waste, the same trick we’ve already seen successfully applied to the Roomba J7. That said, I haven’t tested it on the S7 or S7 MaxV Ultra. Another company, Samsung, made similar claims, but unfortunately, its Jet Bot AI Plus couldn’t perform as advertised, so I need to test the Roborock’s navigational sanity for myself before giving full credit here. will be required.

Winner: Draw

self cleaning capability

This is an area where the Roborock S7 MaxV can claim an undisputed victory. Both robots have base stations that each empty the vacuum’s trash can when it is full. Both systems can also clean 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 replenishes the robot’s water reserves, but it also automatically cleans the S7’s mopping pad. If this task comes to an end, it will be a game-changer.

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

price and value

The Roborock S7 MaxV Ultra feels like a phenomenal machine. With a sticker price of $1,400, it doesn’t come cheap. Of course, iRobot’s solution isn’t even for penny pinchers. You get the same ($1,400) back when you add the price of the $850 Roomba J7 Plus and the $550 Braava Jet M6. And since the S7 makes more for the same staggering pile of cash, my money is on the Roborock. Eventually, I’ll have a more capable system if either is spending that much.

Winner: Roborock S7 MaxV Ultra

overall winner

As it currently stands, the S7 MaxV Ultra holds all the cards. The score of this Floor Cleaner Wars 2 to 1 looks decisive in Roborock’s favor. That said, it’s a paper win, and it hinges on whether the S7 MaxV delivers the same performance as the standard Roborock S7. Time will tell on that front.

The same is true for the machine’s promised pet poop avoidance and automatic mop-cleaning capabilities. So, while the result is looking clear right now, we won’t know for sure until Nerdshala is able to put Roborock’s fancy new robot through its paces. Stay tuned for that.
