These two products are close, in terms of price, so I’m sure you’d be interested to know which one is better? I have spent several hours testing these two products on different categories such as navigation, cleaning, application features, and much more.
I will share all the results in this review. There is a lot to unpack, so let’s get into it.

Introduction to Roborock S7 and Roomba S9+
Roborock S7 and Roomba S9+ represent two of the most outstanding options In this category, with almost identical price tags.
While these products approach the price, their features vary. However, one similarity is the self-emptying capabilities that rid consumers of this menial task.
Hybrid robot vacuum/mop: Roborock S7
Roborock has been making waves lately with its product releases. for the first time S5 Maxwhich was the first variant with an electronic water tank, then the S6 MaxV came with a dual-lens front camera, which enables it to avoid obstacles better than any other Roborock.
Maybe the S7, Best Roborock product so far With the latest scanning technology called VibraRise. It’s the first hybrid robotic mop I’ve tested with vibrating pillowwhich increases its wiping capabilities, enabling it to sweep stains better than most robotic vacuum cleaners out there.
This variant also introduced a host of other upgrades such as a floating brush set and a new brush roll minus the bristles, providing high agitation and reduced curl issues.
while the S7 Has An Empty Dock Automaticallyit’s an extra element You will need to purchase separately. I asked Roborock If they were going to sell it as a bundle like Roomba and Ecovacs, but they didn’t commit to anything, so for now, that’s your only option to enjoy the self-discharge feature.
The Roborock Auto Empty Basin is unique with its two-cylinder design, a wide port connected to the brush barrel, and two additional filters to complement its bag system.
Roborock says the wide harbor will accommodate larger wrecks, But there is a limit (fruit loops tip) Due to the narrowness of the road leading to the cyst.
I tested it extensively, and while I had my doubts, it proved to be an excellent design as it also cleans buildup on the brush roller assembly.

Best-in-class cleaning performance: Roomba S9+
Many competitors have come and gone, but no one is superior to me Roomba S9 With cleaning performance.
The combination of high airflow, wide cleaning path and great excitement makes S9 Class leader in debris sweep.
This alternative picked up the highest averages for surface and inline dirt, cementing its claim to be the best-in-class cleaning robot.
If you want a robot vacuuming robot that is stale and sniffing debris, go for Roomba S9.
The Plus version comes with a clean base station that empties the trash after every run.
Like the Roborock S7, it uses a pouch system but with About 2.5 liters less capacity.
Unfortunately, the Roomba S9 It does not have any scanning capabilities and is only limited to sweeping.
You will have to purchase a Braava product from iRobot to get this functionality.
The high cost may prevent some from getting Roomba S9.
If so, you can take a look at Cheaper options from Roomba such as I3 and I6 (or I7)However, these variants don’t have the extensive extractors or brutal airflow that the S9 brings to the table.
Similarities Between Roborock S7 and Roomba S9+
Robotic vacuum cleaners don’t look alike, but there are similarities under the hood.
Both products are intelligent locomotion robot vacuums that move in straight lines. Each uses an array of sensors to help it track and map its location.
However, the similarity ends there – Roborock uses LIDAR as the primary navigation sensor, which I like because it doesn’t rely on light. The laser is accurate and will work even in a completely dark room.
Roomba relies on a combination of a top-mounted camera and floor sensors for navigation.
The camera will not be as accurate as a laser, it is highly dependent on the light source to function.
iRobot recommends this in their app, and without it, the S9 won’t complete the mapping process, and users can’t save it.
2. Savings Map
Another similarity between Roborock S7 and Roomba S9 The feature is to save their own maps.
The Roomba S9 It can save up to 10 map levels, while the Roborock S7 can save up to four levels.
This is a screenshot of the iRobot Maps tab.
This feature unlocks other great features, the best of which is Containment (more info below).
Users can add containment boxes to each map they save and prevent these bots from entering restricted areas.
Since these areas are added through the app, there is no need to add physical boundaries.
One useful feature offered by these variants is containment. Consumers can draw squares (through the app) that act as “no-go” areas, preventing a robot from entering them.
However, the iRobot app only has “protection zones”, which are square or rectangular areas but no invisible wall feature – something available with the Roborock app.
Invisible walls are lines that have the same function as a containment box [keep out zones or no-go zones] Block out certain areas, but with the option to block out diagonal areas.
Consumers can buy this Robots with their own automatic unloading berthsEmpty the robot’s trash after each run.
Roomba offers the S9+ as a bundle, while the Roborock doesn’t offer the S7, and you’ll have to purchase the dock that deflates automatically separately.
Roborock offers even more customization with four different auto vacuum modes as well as the option to turn off the self vacuum feature.
In comparison, Roomba does not empty the Trash and empties it after every successful boot.
Both types use a bagged system, but the Roborock Dock has two additional filters to complete bag filtration.
The Roborock (larger) has a capacity of 3 liters, while the Roomba is slightly smaller at 2.5 liters.
Another similarity is the ramp style design, which I prefer over vertical ports because there are no alignment issues to consider.
Consumers can safely use docks on hardwood floors or carpets.
Differences between Roborock S7 and Roomba S9+
Next, we will look at the differences between Roborock S7 and Roomba S9There is a group.
1. Basic brush
One notable difference between these robotic vacuums is the basic brush design. The Roborock uses a single roller with rubber fins that spin around, which deflects the brush bundled on previous models.
I like this design better than the older combo brush because it resists tangles better and provides better agitation, especially on surface debris.
In contrast, Roomba uses patented anti-rotation extraction devices, which cover almost the entire width of the robot.
It’s wider than previous iterations of iRobot – I3, I4, I6 and I7, and offers much better efficiency with higher airflow.
2. Side brush
He uses his own Roborock Full rubber 5-prong side brushwhich I like because it offers better durability.
In comparison, the Roomba S9 uses a Redesigned 5-bristle side brush It has been repositioned toward the front end to complement the broader abstracts.
While the diameter of the side brush varies, the speed at which it rotates is similar, which means that it is not as prone to scattering of debris, which helps with efficiency.
The S9+ is the only Roomba in the iRobot lineup with a D-shaped design. This frame is rare in the robot vacuum industry, with only a few brands adapting it (for example, Neato and Dibea).
In comparison, the Roborock S7 uses a more traditional round frame.
Put these two robots side by side; Roborock S7 is slightly wider than Roomba S9. But the difference doesn’t affect their ability to navigate through tight spaces much.
4. Litter box design and size
between the two, Roomba S9+ has a bigger, Top-mountable 500ml trash canwhile Roborock is Smaller at 420ml.
However, trash size should not be a factor with automatic emptying docks because both options will empty themselves.
I love the Roomba S9 The trash can has a wide opening, which makes it easy to clean.
By comparison, the S7’s Automatic Empty Trash doesn’t have the front gate you’ll see in the default bin except for the top door that houses the filter.
if you buy S7 Automatically Empty DockCome With separate litter boxdesigned explicitly for the base station.
They are identical in design but with a slit on one side, which I think is a release value, so air flows smoothly when the base station is working.
Another difference between these litter boxes is the location of the outlet. The Roomba S9 he have Dedicated port at the bottomwhile the Roborock S7 has only Instead it uses the main entrance Where debris flows from the main brush.
5. Automatic degassing basin filtration
Roborock Priority filtration with its automatically emptying dockwhere the first cylinder contains two filters – a primary filter and a HEPA classifier.
It can filter up to 99.99% of dirt and allergens, down to 0.3 microns, the equivalent of a high-quality bagged vacuum filtration.
Roomba doesn’t have any extra filters but just relies on its bags.
Consumers may need to purchase genuine iRobot bags to enjoy this feature as there is no guarantee that third party brands offer the same type of material.
6. Live Map [Roborock S7 only]
Only Roborock S7 has this feature, which helps users to track the location of the bot in real time. LIDAR enables him to plot these lines on a map, which is another measure of his place in the cleaning cycle.
iRobot does not have a live map feature but only shows a drawing of the robot.
7. Purification [Roborock S7 only]
One glaring disparity between these bots is the lack of a scanning feature with Roomba S9.
You’ll need to purchase any Braava products to enjoy the mopping feature, and iRobot says you can sync your S9 and Braava Jet so the last mop after your S9 has finished vacuuming.
The Roborock S7 is the first hybrid robot I’ve tested with a vibrating wiping pad. This feature takes scanning performance to another level.
Here’s a before-and-after shot of red wine stains.
It also cleans juice stains well, but I wouldn’t recommend using any robotic mop on it because it leaves a sticky residue.
Users will have various options, including adjusting the water level settings and mop mode only if the deep setting is selected.
Probably the best robotic vacuum cleaner / mop, considering the vacuuming and mopping performance.
App Features of Roborock S7 and Roomba S9+
These robot vacuums have their own smartphone apps, and we’ll look at the different features that are unique to each brand.
1. Live Map [Roborock S7]
Roborock S7 has a live map that shows the location of the bot in real time. It helps users to keep track of the whereabouts of the bot in the event of a breakdown.
This feature highlights the differences between these brands’ primary sensors – LIDAR vs. Top Mount Camera + Optical Sensor.
You can see in the screenshot above Laser sensor accuracy in mapping. It is the exact representation of the floor plan.
Because LIDAR continuously shoots signals in a 360-degree pattern during its entire operation, It takes less time for Roborock A product for creating a map.
When these signals bounce off the perimeter, they map through the SLAM algorithm. Whatever the laser signals touch represents the surrounding walls on the map.
It also enables the app to have these lines that follow the robot as it goes through its cleaning cycle.
While the iRobot app does not have a live map, you can view it by tapping on this pin icon at the bottom right of the robot’s drawing.
The map you see here is very different from what Roborock drew. It’s not accurate because Roomba mainly relies on this downward-facing optical sensor to find the edges of the room.
So any obstacle you encounter while playing the maps is reflected on the map drawing.
If you look at these screenshots comparing the Roborock and Roomba maps, you can see the difference.
You can see the difference in how the LIDAR and the map’s optical sensor are plotted. LIDAR (left) is more accurate because the laser sensor is constantly firing signals around the surrounding walls. Hence, it is more accurate when the optical sensor is facing downwards; Any obstacle (such as doors or furniture) is depicted as a wall (if that makes sense).
The slash represents the open door going into the hallway, which is not the case on the Roborock map.
2. Invisible wall [Roborock S7 only]
I discussed this earlier in the previous section, but I’ll explain more here. The Roborock S7 has access to an invisible wall feature, allowing users to draw straight and diagonal lines.
Depending on the floor plan of your home, this feature may or may not be useful.
In my home office this comes in handy since a small section under my work desk is full of wires for the router, WIFI connection, etc.
I have added hooks to arrange these cables, but the wires are still exposed.
An invisible wall feature will come in handy if your home has a similar design.
3. Savings Map
Both brands offer map saving capabilities. The Roomba S9 It can save up to 10 maps, while Roborock can save up to 4 maps.
Users can add multiple containment boxes (and invisible walls for Roborock) and name each room (both brands support custom room naming) on each level.
One difference is Roborock as the automatic room recognition feature is absent in Roomba.
Once again, the advantage of the LIDAR sensor is that the S7 does an initial 360-degree scan before powering on.
4. Selective room cleaning
Consumers will also enjoy selective room cleaning for both products. This feature is usable with the scheduling tab, where you can set cleaning operations in a specific room at your preferred time.
Roborock Four options in this categorywhile the Roomba S9 three.
While Roborock app Provides access to these four modes instantlyiRobot doesn’t, and you have to do it Click on the “Custom” option. to show these settings.
But with the excellent excitement of Roomba, it is possible to use the low or medium setting while still achieving the desired results.
The Roborock app also has four water level options for the scanning function.
5. Clean areas [Roomba S9+]
One of the features that iRobot has over the Roborock app is the Clean Zones feature.
It’s similar to cleaning a Roborock area, but with Roomba it’s possible to save these areas, which is a huge time saver if your home has areas that require more frequent cleaning.
Finally, in this section, we will compare the scheduling feature. Both bots offer a scheduling feature so you can set a specific time of the day when they run.
And while you can schedule several tours per day, iRobot has a gap of at least three hours between runs, while Roborock doesn’t.
One possible reason I think iRobot adds this limit is its shorter runtime (only 75 minutes).
There is no minimum gap with the S7 app.
Consumers can also choose which room they want to clean at a specific time using this feature. iRobot app has the option to choose cleaning areas as well as rooms.
While these robotic vacuums are considered “smart mobility robots,” the way each variant is implemented varies.
The Roborock S7 is based on Laser Top Mounted (or LIDAR), and Roomba S9 It uses a top-mounted camera and ground sensors for such.
Using a laser offers different advantages (and some disadvantages) compared to a camera. What is most noticeable is its accuracy and lack of reliance on light. You can run the S7 in a very dark room, and still turn on, while the S9 will struggle.
It also has a larger margin of error in zoning rooms. Even if the partitions are not meticulous, it will still complete a selective room cleaning cycle, while the . file Roomba S9 Maybe not.
The Roomba S9 And it will pass the Roborock S7 in straight lines. One of the differences is Roomba S9+ moving in the same direction (for two-pass running), while the Roborock S7 Cross pattern is used.
Also, Roborock can roam up to three times, and Roomba can roam at most two times.
But with iRobot’s “dirt detection” technology, this discrepancy shouldn’t be a sticking point as it makes extra passes when it detects more dirt.
Another experiment I have with these bots is efficiency, where I spread Quaker oats in strategic areas to check how much they are picking up.
The Roomba S9+ He was a bit better in the field, getting almost all the crumbs after the first pass, while the Roborock S7 needed a second pass.
You can watch the widescreen S9 Plus extracts in action here with clean passes (Watch My YouTube review to see it in action).
A new test that I am implementing on my robot vacuum reviews is the Proficiency Test. I’m doing this experiment along with the coverage test, where I’m adding a timer to check how long it takes the bot to finish a two-track run (if applicable).
Roborock S7 is more efficient to finish running In about 20 minutes and 45 seconds Despite the crossover pattern, more than 10 minutes faster than Roomba S9 that completed the run in 32 minutes.
One factor driving the S9’s time down was its indecisiveness while navigating through narrow quarters under a desk where I put two chairs side by side.
Crossing was not accurate through tight spaces.
Air Flow Comparison
Since robot vacuum manufacturers do not have a universal method for detecting suction and force, it is difficult to compare different brands.
To counter this problem, I have to rely on an anemometer to measure the airflow directly into the cleaning nozzle.
The Roomba S9+ Almost doubles the Roborock S7’s output with up to 25 CFM at the highest setting versus 13.91 CFM.
The air flow variance is confirmed in the results of cleaning tests, where Roomba S9+ It performed better across the board, as these bots tested how each worked with different types of debris. Tried Quaker oats, pet litter, coffee grounds, sand, and more.
But Roborock S7 is a little better than Roomba S9 in hard floor tests and sealing in sand in hard floor experiments.
On the carpet is where the S9+ separates itself from the S7, picking up more debris on both the surface and compact sand tests.
Which is better on hard floors?
You could say it’s a mistake between the two, but I’d give the Roomba a slight advantage due to the superior airflow and extra-wide cleaning path, which makes it more efficient.
It captured 100% of the sand on this surface, and it’s one of the best robot vacuums in this category. There was no build-up on the brush assembly.
In comparison, the Roborock S7 scored 99.8%, which is still respectable.
The Roborock S7 is excellent because it lags in the airflow department; The high results demonstrate improved stimulation from the redesigned brush.
Edge cleaning comparison
Once again, the Roomba S9+ is the best option, with cleaner results, and has picked up the most debris after one swipe.
The Roborock S7 did not perform well, leaving more debris due to a lack of airflow and a rounded frame.
Hair wrap comparison
I used one gram of five- and seven-inch strands of hair for these experiments to see how well the robot’s vacuum could resist tangles on the brush.
It’s a good measure of How well will you handle pet hair.
The Roomba S9+ It performed better in both tests, growing over 80%, while the Roborock S7 had a 75% increase with five-inch strands but significantly less with seven-inch hair (44%).
Little hair wrapped around Roomba S9 extractors;
Most were on the axles, but they are easy to clean.
Roborock S7 hasn’t resisted tangles like Roomba S9+, especially on strands longer than seven inches (check photo). But the good thing about the new brush design is the ease of cleaning.
Which is better on the carpet?
hand in hand, the Roomba S9+ is best based on measured eye tests. It picked up a higher percentage in almost all of our surface and compact dirt tests.
The airflow difference is evident, especially with our deep cleaning test, where the S9% picked up significantly more (93% vs. 78.85%).
If deep cleaning is a deal breaker, go for Roomba S9+.
The Roborock S7 has a capacity of 5200 mAh The lithium-ion battery will last longer – up to 180 minutes on the lowest setting.
while the Roomba S9+ A maximum of 75 minutes at the lowest setting and 45 minutes at maximum power.
Recharge and resume Somewhat negates the differenceHowever, the S9+ will take longer to complete the task and may not be attractive in larger homes.
I use the sound meter from a few meters away to run noise tests with different power settings. Here are the results.
As expected, the Roomba S9+ is the most noisy option because it has a larger motor, Max 74 dB.
Roborock S7 is not far off at its highest at 69.8 dBbut it is less noisy at other settings, not even reaching 65 dB.
A TLC robotic vacuum cleaner will require more than other types of vacuum to maintain long-term performance. I’m going to enumerate the components that need to be looked at in order for it to run smoothly.
- Basic brush roll: The most abused component of any robotic vacuum cleaner, it is responsible for picking up debris. Over time, dirt accumulates on the cylinder and axle. Check at least once a week, especially for people with pets, for any buildup, and clean as needed.
- Side brush: Another misused component is the side brush. Hair is the primary culprit and will wrap around the arms and base. Again, check and clean at least once a week.
- fall sensors: Underneath these robots is a set of sensors, preventing them from falling off cliff points. These are drop sensors, and contaminants can stick to the surface over time, triggering an error code. Wipe it down once a month with a clean, dry microfiber towel.
- Wheels: Wipe the three wheels (side wheels and caster wheels) with a clean, dry microfiber towel to clean any surface dirt.
- Dustbin and filter: Consumers will still need to check and clean the trash even with the automatic emptying feature. Yes, the dock will empty its contents, but splinters will be left inside the trash and on the filter, so do a visual check once a month and clean them up if necessary.
- Auto empty port: Ensure that the outlets on the base station that automatically deflate are free of any build-up of debris and potential clogs.
- base station: There is a slight difference for both brands here. For the Roborock, you will need to clean the primary filter and replace the HEPA filter once it is dirty. iRobot does not have these filters, so replacing the bag is the only thing that needs to be done.
Availability of spare parts
iRobot has the advantage here because it has been on the market for much longer and is more popular. Consumers will have no problems getting more obscure parts like the side brush motor, brush roller assembly, and even the S9 battery. Roborock has good availability, at least for consumable parts like filters, side brushes, pads and main brush, but other components like the battery or drop sensors will be hard to find.

Which is the best choice, Roborock S7 or Roomba S9+?
Both options are incredibly close in price, but the Roborock S7 is a winner when you factor in the features. It is arguably the best hybrid vacuum cleaner and mop available right now, considering how well it works on both sides.
None of the other hybrid products I tested came close to vacuuming and mopping performance.
The Roborock app also provides a better user experience with features not found in the iRobot app (eg invisible wall, live maps, etc.) and more frequent updates.
However, one thing that happens to Roomba is his performance, especially how well he picks up the rug.
I also like the modular design of iRobot products, which makes them Easy to cleanso maintenance shouldn’t be a concern.
To help you decide, I’ve listed the reasons why you should choose each of the alternatives here.
5 reasons to choose Roborock S7
- Two in one product: Roborock S7 offers better versatility than Roomba S9With excellent scanning ability.
- Effective Mobility: An important advantage of LIDAR over the camera is its accuracy, which enables the S7 to be more efficient to navigate, even in confined spaces.
- High quality cleaning: Enjoy Roborock S7 on its own vs. Roomba S9 In cleaning tests though, the airflow is reduced.
- More containment options: In addition to restricted areas, Roborock has an invisible wall feature so that people can block diagonal areas on the map. It’s a wrinkle not available in the iRobot app.
- least expensive: If you take into account its scanning ability, the S7 is much cheaper than Roomba S9 + Braava combo.
4 reasons to choose Roomba S9+
- Superior in deep carpet cleaning: T.he is Roomba S9’s Its high airflow makes it a better choice for cleaning dirt on carpets.
- wide hoods: While the Roborock S7 finished coverage faster, the Roomba S9 I picked up more debris on every pass thanks to the wide hoods and higher airflow.
- Better Edge Cleaning: The square interface makes the S9 more convenient to clean the edges.
- Best-in-class cleaning performance: People who prioritize the performance of a vacuum cleaner over anything other than a robot vacuum should think strongly about Roomba S9+. It outperforms all other brands with its combination of high quality excitement and airflow.
Verdict: Your choice will depend on what you prioritize
It is difficult to declare an outright winner among these brands because they both have something compelling to offer.
Roborock S7 offers better versatility and better application experience, while Roomba S9+ Offers best-in-class cleaning performance.
So choosing one will boil down to Your preferences and needsbecause the price difference is not much.
People who Need scanning feature And you don’t want to spend more on another bot, you should consider the Roborock S7 because it offers both functions and it does it at a high level.
But those who want Uncompromising cleaning performance Have to look at Roomba S9. It cleaned better than any other robotic vacuum cleaner I tested to date, outperforming both surface and compact dirt.
