After completing the Roomba J7 review, I thought it appropriate to compare with other top-notch bots like the Roborock S7.
Currently, these bots are the main brand of their respective brands (for now), and I’m curious how these products compare.
Each one brings something unique to the table. The S7 has an industry-first sonic lift and sweep technology, making it one of the best floor-cleaning robotic vacuums.
And the J7 is iRobot’s first choice with a front camera and LED light, which enables it to avoid obstacles better than any robotic vacuum I’ve tested (so far).
I’ve tested these bots extensively to see which option is the best, and the results are great.

Introduction to Roomba J7 + and Roborock S7 +
Robot vacuum technology has evolved over the past five years. I’ve seen major improvements in two areas – navigation and obstacle avoidance.
The Roomba J7 and Roborock S7 represent how manufacturers have improved their products.
We’ll look at these unique features in this article, as well as their similarities and differences.
Best in class for obstacle avoidance: Roomba J7 +
After detecting a file S9I was just curious what iRobot could do to show off.
And it didn’t take long to find out. The Roomba J7 + It is this appearance, and its biggest upgrade is the front camera sensor, which helps it avoid obstacles.
It’s not the first Roomba With this technology, but it is the first of its kind with a combination of LED and camera, which helps it avoid obstacles even in dark areas.
One aspect that fascinated me was the algorithm. J7 will not approach obstacles, reducing the risk of touching pet feces or wires.
iRobot is very confident in its technology, and has a POOP guarantee or official promise to the pet owner.
He. She Basically countries That if your J7 touches a dry pipe, iRobot will replace it for free.
I tried it on the feces of large and small pets (obviously fake), and did not touch it during the experiment.
The iRobot app feature enhances the ability to avoid obstacles, allowing users to identify these areas as permanent or temporary obstacles.
If users mark these flags as permanent, the iRobot app creates block zones for you.
Another upgrade for iRobot is the more compact clean base station.
iRobot has carved out a significant portion of its vertical real estate.
It’s wider, but still within the confines of the bot, so it shouldn’t affect storage.
The J7 retains the ramp-style base station of its older brothers, and I3, I6, S9with the same capacity of 2.4 liters.
Another benefit of the new design is an additional storage slot for a second bag.
Please note that older bags (I and S-Series) fit J7. I like this forward compatibility because there won’t be any supply issues.
You can use the i7 case in your J7 without any problems and possibly save money in the long run.
Best-in-class scanning: Roborock S7 +
Roborock is one of the most innovative brands I’ve tested, and the S7 is proof of that.
Currently, this is their latest robotic vacuum, but with the pending release of the S7 MaxV, its prime state will no longer last.
Roborock introduced many innovative features into the J7, couched into one fancy term: VibraRise.
Vibra refers to the vibrating wiping pad, a feature that is a first of its kind, which helps it be more efficient at wiping stains.
Height indicates the height of the pad when you spot the rug.
This variant is also the first Roborock with a self-emptying base station, with a large 3-liter bag.
You will notice that the base station has a filter, which is rare. I think the S7 has this because some markets Offer a bagless version.
Using one template for all products across different markets makes sense from a cost perspective.
The S7 uses LIDAR for navigation and is one of the most efficient options I’ve tested.

Similarities Between Roomba J7 and Roborock S7
Next, we’ll look at the similarities between the Roomba J7 and the Roborock S7, starting with the design.
Both robots use a circular frame with one side brush. One difference is the J7 using the patented anti-spin hoods.
It is the only robot in the North American and EU market to have this feature since iRobot holds the patent.
2. Packed system
Another similarity is the use of a clean, bagged base station, which means the bag stores debris collected from the robots.
I love bag systems because they keep dirt inside a sealed bag, so allergens stay inside while you get rid of them.
The Roborock bag is slightly larger (3.0 L) vs. the Roomba (2.4 L).
These robots use a ramp shaped pavement (I love it) because it provides better stability than a vertical one.
The robot parts on the dock and then starts a vacuum drive to suck up the contents after each run.
One difference is the port size. The Roborock has a larger port that connects to the main brush.
The Roomba port is smaller and connects to a dedicated slot under the robot.
4. Intelligent navigation
The Roborock S7 and Roomba J7 are smart navigation robots, so both can track their location.
Recharge and resume are available for both, and range expansion.
The S7 uses LIDAR and SLAM, while the J7 uses the Camera Sensor and SLAM (VSLAM).
Differences between Roborock S7 and Roomba J7
In this section, we will look at the differences between these bots.
1. LIDAR VS CAMERA SENSOR
The most obvious difference is the basic navigation sensor that each brand uses.
All Roborock products use a LIDAR sensor. And so, you’ll see this disk above the robot, containing the laser sensor.
The Roomba uses the camera sensor on the front.
This may be a deciding factor as the LIDAR cover adds to the S7’s vertical footprint.
The J7 doesn’t have that vertical overflow since the camera has been moved to the front. In addition, iRobot removed the infrared sensor, lowering its overall height (to 3.63 inches).
It fits under this sofa with a clearance of 3.8, so it’s something to consider if you own furniture like this.
2. Brush roll design
The next variation is the brush roll design. Roborock introduced a bristle roller with the S7, while the J7 uses the same counter extraction rollers as the I6/I7.
Here’s a closer look at J7 counter-circulation hoods.
Roborock also got a little less sentimental when it unveiled the S7.
These brush rollers provide excellent aeration since the S7 (13 CFM) and J7 (7 CFM) don’t have a lot of airflow.
3. Side brush
The side brush design is another difference between the Roomba J7 and the Roborock S7.
The J7 uses iRobot’s three-pronged side brush with bristle tips, while the Roborock has a five-pronged rubber side brush.
I like the Roborock design better because it doesn’t spin at the same speed, and it has better durability.
4. Design and placement of a litter box
The Roborock S7 has a trash can attached to the top, while the J7 is rear-mounted.
There is not much difference with the size of the dirt. The S7 has a slightly larger capacity at 420ml versus the J7’s 400ml volume.
But with the self-discharge feature, dirt size shouldn’t be a deciding factor unless you choose the robotic variant only.
5. Automatic discharging station design
While both options have an automatic discharge station, there are noticeable differences.
The J7 uses a lower base station with one narrow port to get rid of dirt. It has a storage slot for an extra bag.
In comparison, the S7 uses a double-barreled design, containing the case and filter. Unfortunately, the S7 Auto Unloading Station doesn’t have any storage space for extra bags.
6. Application differences
The Roomba J7 and Roborock S7 both have smartphone apps, which unlock all the features.
I would encourage consumers to download these apps to get the most out of these bots.
Overall, I like Roborock because it has more usability features like live map and invisible wall.
It can save up to 4 map levels and has features like selective room cleaning and zoned custom cleaning, where users can click a specific room on the map to clean.
The iRobot app lacks the live map or the invisible wall feature, but it does offer features that are absent from the Roborock app.
One feature is Clean Zone, similar to custom zone cleanup, but one difference is that users can save these zones, saving time on having to repaint each time.
Helps users identify zones, which helps identify high-traffic zones.
Another feature absent from Roborock is the iRobot Genius. This feature is available in all Roomba options and uses your phone’s location services for automation features such as turning on the bot if you leave the house.
The Roborock S7 has a scanning feature that is absent in the Roomba J7. It has a new technology they call VibraRise, which combines two new technologies – a vibrating wiping pad and a lifting squeegee.
The vibrating wiping pad makes it more effective at removing stains because it’s more exciting.
But it still pulls a damp pad onto the surface, so it’s limited to the spot it can clean.
I wouldn’t recommend it for wet messes or large stick stains.
Can’t absorb into a liquid like ILIFE W400 or W450It does not contain aerosols like the iRobot Braava.
8. Avoid obstacles
The Roomba J7, with its front camera, can avoid obstacles better than the S7.
It featured dodging things like wires, even extended wires, and thin cables without any issues.
Also, he was good at avoiding pet feces, both small and large.
An important aspect of this is the iRobot algorithm that does not allow the robot to get too close to the obstacle, reducing the risk of the side brush coming into contact with the tube or the wires getting tangled on it.
App Features for Roomba J7 and Roborock S7
We are going to learn about the different app features of Roomba J7 and Roborock S7. I will highlight the salient features of each variant.
Please note that some of the screenshots you will see below are from the older Roborock app, but the functionality remains the same.
1. Live Map [Roborock S7]
Only the Roborock app has a live map that shows the real-time position of the bot on the map.
It gives users an alert of where the bot is on the map and helps locate it if something goes wrong.
iRobot app does not have this feature and only shows a robot drawing while running.
2. Containment [Both]
iRobot and Roborock apps include containment features that help consumers block restricted areas.
Roborock has more options with invisible wall, restricted areas, and mop-free areas.
The latter two are similar in that they block a square or rectangular area, and I think those features are redundant with the S7’s mop lift feature.
The invisible wall feature gives the S7 an edge where users can block out diagonal areas.
iRobot only has a zone blocking feature.
One of the great features of iRobot is that consumers can use the exclusion zone with obstacle avoidance technology and mark them as permanent obstacles, thus creating (automatic) exclusion zones.
3. Save the map [Both]
Both apps can save maps, but the iRobot app can save more (up to 10) than the Roborock app (only 4).
Consumers can customize each map level by manually creating divisions, naming rooms, and adding containment.
However, only the Roborock app has a map detection feature to select the correct map level based on an initial scan.
iRobot does not have this feature because it uses the camera. It’s a huge advantage a LIDAR bot like the S7 has over a VSLAM bot.
4. Map graphics
You can see the differences between LIDAR and a camera based robot with map graphics.
The screenshots above show that Roborock’s laser sensor is more accurate in mapping.
360-degree scanning helps create a more accurate graphic from Roomba’s VSLAM.
iRobot products rely heavily on an optical sensor underneath to determine the circumference of an area.
Roborock is also the most accurate of the two robots that create partitions if there are doors.
5. Clean area [Roomba only]
One of my favorite features of the iRobot app is the clean zone.
Allows consumers to draw boxes in potentially high-traffic areas, more than one, and save them (using custom names)
This is a time saver since there is no need to draw them again, and can be used with the scheduling feature, helping to target these areas more frequently.
6. Multi-pass operation
Both apps also enable users to set multi-pass runs. Roborock performs two passes by default with a maximum of three passes option using selective room cleaning or the area cleaning tab.
Multi-pass triggering also unlocks the crosshairs pattern on the S7.
Roomba system is different. The dirt detection system gives it an advantage over the Roborock because it makes additional passes back and forth in the most polluted areas.
Plus it contains these options.
There are three options: room size clean, daily clean, and extra clean. Choosing one depends on several factors such as the size of the room or the type of surface.
You can opt for extra cleaning inside small homes and daily cleaning for larger homes to increase the range.
The Roomba J7 and Roborock S7 use SLAM technology. Thus each variable can be navigated intelligently. Intelligent navigation means the J7 and S7 can track their location and clean specific areas.
Recharge and resume are also available.
These robots will move in straight lines, which makes them efficient. And both seem to have a criss-cross pattern, which helps with accuracy.
However, Roborock is more efficient with laser navigation. I tested it several times, and it was much more efficient, finishing up much faster than the J7.
Efficiency is the hallmark of most laser robots, and the S7 is no exception.
It was better at navigating through tight spaces, where it feels more decisive than the J7.
However, the added height of the LIDAR cover means it won’t fit under furniture under four inches, so that’s something to keep in mind.
The J7’s low profile design is its biggest advantage and somewhat negates the inefficiency drawback.
Another feature of iRobot is its dirt detection feature, which gives it better accuracy, especially on carpets.
It makes extra passes when it detects more debris, something that’s been absent in Roborock or any other brand of vacuum cleaner since iRobot holds the patent.
The Roborock S7 is better than the J7 with coverage, catching more Quaker oats during its three-pass run than the J7.
This experiment highlights the accuracy of LIDAR because there are fewer points missing from VSLAM than iRobot.
The Roomba J7 was decent, but the fast spinning side brush and low airflow didn’t pick up much debris.
Even with dirt spotting, it still fell short in that aspect versus the S7.
Another advantage of using LIDAR is efficiency, and the contrast between the Roomba J7 and the Roborock S9 is great.
The S7 finished it up in 20 minutes 45 seconds: over 15 minutes faster than the J7 (35 minutes 26 seconds).
The Roborock did well due to its ability to navigate tight areas well with more decisiveness.
The J7 tends to hunt and stall in these areas. Using the camera also affects the accuracy with which you pass through a maze of chair legs.
It was better than previous Roomba models like the E5 which didn’t perform well.
Air Flow Comparison
Next, we’ll look at how much power these robots have.
Since robot vacuum manufacturers do not have a standardized way of detecting power, I use an anemometer to check the air turbulence (or airflow) at the cleaning head.
It’s a good measure of how a robot vacuum is performing. Usually, high air flow robots such as Roomba S9 Sweep up debris well.
There are other factors, but airflow is critical.
Here are the results.
|adjust power||Roborock S7||adjust power||Roomba J7 +|
|calm||8.2 CFM||shortening||7.27 cubic feet per minute|
|balanced||9.68 cubic feet per minute|
|turbo||11.33 cubic feet per minute|
|the above||13.91 cubic feet per minute|
The Roborock S7 nearly doubles the J7’s airflow output at 13.91 CFM. It’s a big reason why it performed better than the J7 in most cleaning tests (more below).
I used a mixture of debris such as ground coffee, quinoa, pet droppings, sand, hair and Quaker oats for cleaning experiments to check how well these robots clean.
Based on the results, the Roomba J7 was better overall, but that’s because it did better in our deep cleaning tests (85% vs. 78%).
But the S7 did better with picking up surface debris due to the superior airflow, although no dirt was detected.
The eye test also shows the S7 to be slightly better, making passes cleaner, even with heavy debris like pet litter.
Another aspect that helped the S7 clean better is mobility. Three-pass running, combined with tighter crossovers, helps the S7 dump more debris.
Which is better on hard floors?
Again, looking at the test results, the S7 is better than the J7 with surface debris experiences.
I picked up more Quaker oats, quinoa, pet litter, and Quaker oats. The S7 didn’t have the J7’s side brush scattering issue.
The S7 is also better in the sand test on hard floors (99.8% vs. 98.64%), which is my benchmark for hard floor performance.
Edge cleaning comparison
The Roomba J7 and Roborock S7 did quite well for a round-shaped robot, capturing a good portion in this test area.
Here is the before and after shot of the Roomba J7+.
and the Roborock S7.
There is not much difference with the results. Wasn’t as clean as Roomba S9+ With a square forehead, but the results were respectable.
One problem with low airflow is its inability to catch debris on a quarter inch crevice.
Both robots struggled to pick up dirt in that area.
Hair wrap comparison
The Roborock S7 is better at picking up hair, than five- and seven-inch strands. Again, higher airflow is a factor in increasing its pickup.
But more hair will wrap on the S7’s cylinder than on the J7. However, the lack of bristles makes it easy to clean.
Most of the hair is wrapped on the J7’s hubs, which are a silver lining for this test, so it’s easy to remove.
Which is better on the carpet?
It’s a mixed bag with carpet performance. The S7 was better with surface debris (98.9% vs. 96.92%), but J7 hoods with opposite rotation picked up more sand in the deep cleaning test (85.75% vs. 78.85%).
Not surprisingly, Roomba has dirt detection and Roborock doesn’t.
This is why Roomba products perform so well on carpet, despite the lack of airflow.
Only Roborock J7 has scanning option. It’s something that’s absent on the J7, and you’ll have to purchase any of the Braava series bots to enjoy this functionality.
If mopping floors is a big deciding factor, the Roborock J7 is an excellent choice.
The vibrating wiping pad is more efficient than a traditional robot squeegee at removing stains.
Provides an agitation element absent in older robot wipers. Take a look at these before and after shots.
The S7’s scanning ability is excellent, but there are limitations to what can be scanned.
Since it only pulls on a wet pad, scrubbing off sugary stuff like smoothies isn’t practical.
I tried it, and it left a sticky surface afterwards.
There is nothing wrong with the design, but pulling a wet pillowcase has its limitations.
One of the features that the S7 has over the J7 is its large capacity, 5200mAh battery.
Roborock says it can be played up to 180 minutes and combine it with the efficiency of the S7; The S7 will have an excellent selection.
The J7 has a 2410mAh Li-ion battery (larger than usual) Running time 85 minutes.
It won’t work for long, and I wouldn’t recommend it inside larger homes, even with recharging and resuming.
It eliminates the inconsistency in runtime, but may not be a viable option within larger homes.
There is not much difference between Roomba J7 and Roborock S7 with noise.
The S7 is obviously louder at around 70dB at the maximum setting, but the 6dB contrast isn’t much, considering the S7 roughly doubles the J7’s power output.
However, the clean J7 base station is loud, screaming at more than 84 decibels. The good news is that it only works for a few seconds, but it’s not something you want to run late at night.
As with all robot vacuums, the Roomba J7 and Roborock S7 require regular maintenance to operate at their peak.
I would argue that it is more important for a robot vacuum than any other type of vacuum because these depend on sensors to function.
Any additional friction will hamper its efficiency and performance. I will list the components that will need to be cleaned or replaced and the time intervals for each.
- Basic brush: Cylinders are the most widely used component of any robotic vacuum. It is responsible for picking up debris. Clean it once a week to remove any dirt and hair that has accumulated on the drum and hubs.
- Side brush: The other part that consumers need to check is the side brush. Hair tends to curl at the ends and the base, so be sure to brush it once a week to prevent unnecessary frizz.
- Dustbin and filter: There is no need to empty it manually using the self emptying feature. But you’ll need to check it twice a month for any debris buildup, especially on the filter.
- fall sensors: Use a clean cloth to clean the drop sensors to prevent an error code from launching and disabling the robot. Do this task once a month.
- Automatically empty base station: Dispose of the bag once full. Make sure the port is clear of any obstruction.
- base station filter [S7 only]: Check the Roborock S7 filter once a month and wash it if necessary. Make sure it is completely dry before reattaching it.
- robot body: Use a clean microfiber town to wipe the robot’s body and clean any accumulated dust and fingerprints.
Availability of spare parts
Roomba will always have the advantage of having spare parts because of its popularity. But Roborock is slowly catching up as more third-party brands sell parts like filters and brushes.
However, Roomba has more options and availability, especially with hard-to-find parts like the side brush motor and the battery.

Which is the better option, Roomba J7 + or Roborock S7 +?
Each form brings something unique to the table, so choosing one depends on your preference.
The Roborock S7 is more versatile and efficient thanks to its ability to scan and navigate with LIDAR.
In comparison, Roomba J7 is better at avoiding obstacles thanks to the front camera and LED array.
Because of the superior airflow, I leaned toward the S7 with its cleaning performance, specifically on hard floors.
But if you have pets and need a robot capable of avoiding dry poo, consider the Roomba J7.
5 reasons to choose Roborock S7
- More versatile: The Roborock S7 is one of the better robotic and mop hybrids for both tasks.
- Better Efficiency: The LIDAR sensor and SLAM algorithm make it more efficient to navigate in confined spaces.
- Bigger battery: The 5200mAh battery gives the S7 a better range (up to 180 minutes).
- Best value: Consumers will get better value from the S7 because it can vacuum and mop without buying another robot.
- Excellent cleaning performance: In most cleaning tests, the S7 performed better than the J7.
4 reasons to choose Roomba J7
- Avoid obstacles: J7 is the best robot vacuum I’ve tested at avoiding wires and pet poo.
- Better Deep Cleans: Not surprisingly, the J7 performed better than the S9 at cleaning embedded sand using anti-spin extractors and dirt detection.
- Extra bag storage: The J7 clean base station has a storage slot for an additional bag.
- Set permanent obstacle areas: iRobot app has this cool feature that allows users to set permanent zones and create block zones automatically.
Verdict: The choice depends on your preference
While the Roborock S7 is the best performing robot vacuum cleaner in most cleaning experiences, the Roomba J7’s obstacle avoidance feature is baffling.
If you want a robotic vacuum cleaner that can avoid pet feces or dry wires, you should consider it.
Other than that, I recommend the Roborock S7 because it’s more efficient, cleans better, and is more versatile.
