Roborock S7 MaxV Ultra vs Roomba Combo j7+: Which One Wins?

In a nutshell, what are the differences between the Roborock S7 MaxV Ultra and the Roomba Combo j7+?

  • The Roborock S7 MaxV Ultra’s mop is more advanced than the Roomba Combo j7+’s.
  • The S7 MaxV Ultra comes with a more advanced dock than the Combo j7+.
  • The S7 MaxV Ultra has a calling function, while the Combo j7+ does not.
  • The S7 MaxV Ultra can navigate more efficiently than the Combo j7+.
  • The Combo j7+ has two main brushes, while the S7 MaxV Ultra only has one.

Difference 1: The mopping systems work differently.

The S7 MaxV Ultra’s mop is always under the robot. When carpet is detected, the mop is retracted upwards and into the robot. However, this retraction is only enough to avoid getting low pile carpet wet. If you have middle to high pile carpet, it won’t be enough to prevent them from getting wet.

When a hard surface such as tile or hardwood is detected, the mop is extended and vibrates left and right 3,000 times per minute to really give the floor a good clean.

The Combo j7+ is sits under the robot while it mops. But when carpet is detected, the metal arms on the robot lift the mopping pad up and over the top of the vacuum, where it sits until the robot moves off the carpeted area. The Combo j7+’s mop is not as powerful as the Roborock’s in that it does not vibrate, but the metal arms on the Roomba do exert constant downward pressure to give the floor a good wiping down.

The Roborock is better in that its mop “scrubs” left to right to really give the floor a good clean.

The Combo J7+ is better in that there is no risk of getting your carpet wet no matter how soft or high high-pile it is.

Difference 2: The Roborock S7 MaxV Ultra’s companion dock has more functions than the Roomba Combo j7+’s.

The S7 MaxV Ultra’s Empty Wash Fill Dock doesn’t only recharge your robot vacuum and give it a place to rest.

It also automatically empties the robot’s dustbin, washes the mop, and refills the robot’s water tank every time it docks.

It means you don’t need to wash the mopping pad after every cleaning session, which saves a ton of time. You do, however, have to keep an eye on the dirty water tank, since sitting dirty water does start to smell pretty quickly.

The Combo j7+, on the other hand, comes with only the auto-emptying Clean Base. This dock will recharge the Combo j7+ and empty its dustbin automatically, but it won’t be able to wash the mopping pad or refill the water tank like Roborck’s dock can.

If you don’t mind cleaning the mopping pad manually, the Combo j7+ is less expensive and will suit your needs.

If you’re looking for a robot vacuum and dock that takes care of almost everything for you, the S7 MaxV Ultra is worth every penny.

Difference 3: The S7 MaxV Ultra has video calling for some reason.

If you’re away from home and feel like checking in on the kids or your pets, you can do so with the S7 MaxV Ultra.

Because the robot vacuum has dual front-facing cameras, you can use the Roborock app to look through the camera into your home. You can speak through the robot vacuum and have a conversation through the Roomba. This

While the Combo j7+ also has a camera, it doesn’t have a call function. You thus won’t be able to speak with anyone at home through the robot vacuum.

I’m not sure how I feel about this…feature. But it’s there for those who might have a specific use case for a roaming robot teleconference device.

Difference 4: The S7 MaxV Ultra navigates more efficiently than the Combo j7+.

The S7 MaxV Ultra uses LiDAR to navigate your home. Typically, LiDAR robot vacuums are more precise, and the S7 MaxV Ultra is no different. The maps it creates are much more accurate than the Roomba.

Also, the Roborock cleans significantly faster than the Roomba. It takes the Roomba about an hour to completely vacuum and mop my house, but it takes the Roborock just under 40 minutes. This may be due to my layout and the combination of area rugs and hardwood in my house, so your results may vary.

In any case, the general consensus seems to be that the Roborock S7 MaxV Ultra is much more efficient than the Roomba Combo j7+.

Difference 5: The Roomba uses dual brushes whereas the Roborock uses a single brush.

Roombas are equipped with a unique dual brush system that helps to provide a deeper clean for your floors. The two main brushes work in tandem to pick up more dirt and dust. The first brush is designed to loosen up dirt and debris and the second brush sweeps the dirt and debris toward the intake.

The Roborock’s single main brush is effective, but does not perform as well as the Roomba Combo j7+ on carpets. If your home has a lot of carpeted areas, the Combo j7+ will probably be able to clean them more effectively.

Both robot vacuums use rubber brushes without bristles, which means they are really easy to maintain. Hair strands seldom get stuck on the brushes and those that do are easily removed.

Similarities between the Roborock S7 MaxV Ultra and the Roomba Combo j7+

Similarity 1: Both models are able to recognize and avoid certain obstacles on the ground.

Both the Roborock S7 MaxV Ultra and the Roomba Combo j7+ have cameras, so they can both identify objects on the floor. These include shoes, cables, toys, and even pet waste.

When the vacuums see an object on the floor, it’ll try to determine what it is and whether it’s safe to push the object out of the way. If it’s not sure, it’ll err on the side of caution and ask you what it should do the next time.

This is great if you have pets at home. Most pets are house-trained but you never know for sure what might happen when you’re not around. You won’t need to worry about either robot vacuum making a mess worse by running over it.

Similarity 2: Both models will top up their batteries if they start running low on power in the middle of cleaning.

If you have a large house or you like running the highest settings, your robot vacuum will be more likely to run low on battery before completing its cleaning session.

Both the S7 MaxV Ultra and the Combo j7+ will return to their base before their batteries completely run out.

The robot vacuums won’t have to start over when they need to pause their cleaning to recharge. Once they have sufficient power, they’ll automatically go back to the spot where they stopped and pick up from there.

They’ll then continue with the rest of the cleaning session until it’s complete.

Similarity 3: Both have a ton of cleaning functions.

Though these cleaning functions have different names, they work in near-identical ways. You can access the saved maps on both the Roborock app and the iRobot app to draw various zones over specific areas in your home.

With the Roborock, you can draw no-mop zones over the areas where you don’t want your robot vacuum to clean. You can also draw no-go zones over the areas that you don’t want the robot to enter at all. Finally, you can draw invisible walls over doorways and thresholds if you don’t want your robot vacuum to enter certain rooms.

With the Roomba, you can use clean zones and keep out zones to direct your robot vacuum to where you do and where you don’t want it to go. You can also use the virtual walls feature, which works the same way as Roborock’s invisible walls.

You can use these functions to customize your robot vacuum’s cleaning sessions and ensure that it focuses on the areas that you want it to clean.

Similarity 4: Both models have app and voice control.

The Roborock app and the iRobot app have all the options and controls that you need to send your robot vacuum on its way. Both apps will allow you to set cleaning schedules, access saved maps, draw zones, and more.

You can also link either robot vacuum to Google Assistant, Amazon Alexa, and Siri. All three will enable your robot vacuum to receive and act on voice commands, so you won’t have to access the companion app to start or stop a cleaning session.

It’s important to note that both your phone and your robot vacuum need to be connected to the wifi for you to use the app and voice commands. You’ll still be able to turn your robot vacuum on and start a cleaning session by using its buttons, but you won’t be able to do much else.
