Incredible performance, effective cleaning at a great cost
Roomba S9+ review
When iRobot launched the S9 a few years ago, it was a complete redesign from the ground up. Not only did it have a new frame, but most of the design elements from previous Roombas have been eliminated Prioritize cleaning performance. Every aspect of this robot focuses on efficiency, starting with Wide hoods for the clean base stationTest results reveal that this is the case. However, there are issues with the S9 that you’ll see as you read through this review, so whether or not this bot is worth it will depend on whether you can live with the shortcomings.

- insanely Advanced Air Flow (25 cubic feet per minute) makes this Best performing robot vacuum (to date)
- Empty the trash is yours
- wide hoods Enable it to capture more debris on each pass
- trash easy to empty Thanks to the wide opening
- decent dirt capacity (500 ml) – In case you choose the S9 variant without the clean base station
- Insanely expensive
- The app does not offer the best user experience (lacks many features)
- Depends on the light source (not optimal for use in dark conditions)
Introduction to iRobot Roomba S9+
iRobot pioneered self-dumping robot vacuums when they introduced the i7, and with the S9, they’ve taken it to a whole new level in terms of performance.
The Roomba S9 he is iRobot’s current flagship robot vacuum With the largest air flow, the best cleaning performance, but unfortunately, the most expensive option.
Let’s move on to the iRobot upgrades that went into the S9.
1. New look
Unlike previous iterations of Roomba, the S9 now has a D-shaped frame, similar to Neato Botvac . Series. I don’t know why iRobot made the change, but one thing is for sure – these changes are all functional and contribute to this alternative being the Best in class When it comes to cleaning floors.
2. Wide hoods
Changing the design framework enables iRobot to be compatible with broader extraction devices. It’s wider than almost all other brands, except for the 9.5-inch Neato Botvac. S9 still used The same rubber extracts Like m 6/ i7, only longer.
These broad extractors improved the efficiency of the S9 by 2 times compared to Roomba I6 and The result is cleaner passes With no debris particles between the rows.
It’s wider than any other robot vacuums I’ve tested, with the exception of the Neato Botvac.
Take a look at the size difference between Roomba S9+ and i3 +.
The size discrepancy is shown in this side-by-side image.
3. Side brush redesign
Moving the primary rollers also necessitated changing the side brush. The new design has a file Smaller diameter but with two prongs.
Don’t spin as fast as before Roomba models; And then it won’t scatter much debris.
Its main function is to pull dirt from the edges and pull it towards the main brush because it does not fall out on the sides. iRobot calls this technology cutting edge, and tests (at least my experiences) reveal that it works! More on that here.
4. Bigger taller litter box
All Roomba models of the current generation before S9 I used a back litter box. iRobot changed things with the S9 by moving it upwards. Moving has improved usability as it is easy to remove with the integrated handle.
Another upgrade is the capacity, which is 25% more than I6 / I7 (400 ml vs. 500 ml).
The amount of dirt wouldn’t be a problem with a clean base station, but it could be without it, so it should be noted.
It has a larger HEPA filter with easier access from the top.
The wide opening makes emptying and cleaning easier. Since the motor is not inside the container, the entire set is washable if it gets severely damaged.
5. Larger port (for a clean base station)
The S9 has a larger port where it uses the second vacuum on the clean base station to suck the contents out of the robot’s dustbin. It does an excellent job of cleaning the contents from the dust container, even hair particles.
What is the difference between Roomba S9 And the S9 +?
There are two S9 options – S9+ (with clean base station and S9 (without auto-discharge) at least on Amazon.
Choosing the “plus” version is more expensive because it has a self-discharge feature, with a second vacuum cleaner inside the dock cleaning the robot’s dustbin after each run.
But only the S9+ is available on the iRobot website. My choice would be the plus version, obviously to enjoy Benefits of automatic discharge.
base station cleaning
The iRobot design is one of the best I’ve seen because of its simplicity. It’s a one piece, so expect it to hold up well in the long run, and I like that consumers have a lot of choice in terms of where to buy the bags. iRobot sells bags, but a lot of third-party brands also sell them at a cheaper cost.
You can place it on hard floors or carpets without worrying about any alignment issues because the port that connects the trash can to the base station is located under the robot.
While iRobot does not specify the capacity, I think it is Approx 2.5 liters Since the S9 bags are close in size to other brand, Yadi Fak Station.
I6/I7 and S9 bags are identical, so you can’t find specific S9 bags; The i6 versions will fit just fine.
From the i7, iRobot VSLAM to the premium robot vacuum line, the same technology used in the S9.
VSLAM or Visual SLAM combines a top-mounted camera and SLAM, giving this robot enough intelligence to navigate efficiently.
Like its LIDAR-based counterparts, it can move in straight lines, clean certain rooms or areas, and determine its location with the help of an optical sensor underneath.
But using the camera sensor has its limitations. If you’ve ever done anything photography, you’ll quickly realize the difference between a good photo and a great photo It can be switched to lighting.
With VSLAM, this is also the case. The S9’s top-mounted camera needs lighting to function. It is definitely necessary for mapping during the initial run, and iRobot specifies it in the app.
While it can operate without light thanks to the optical sensor, it will not perform well, increasing the risk of not completing the task.
It doesn’t need a very bright room to function, but it does need the right amount of light to move around efficiently.
I’ve noticed that iRobot has fallen behind in aggression, at least for its premium line (I6, I7, S9), and it doesn’t hit furniture as hard.
He’s also managed to avoid getting stuck in a wedge between narrow furniture legs like this office chair, and to navigate this maze well.
However, it is not as effective or decisive as the LIDAR robot (RoborockNeato) in this aspect.
One feature with a camera-based sensor is the lower profile. Without a LIDAR cover, the S9 fits better under furniture (under 3.2″) than Roborock, DreamOr any robot with an overhead laser.
The Roomba S9 Compatible with the iRobot app, we’ll take a look at its list of laundry features.
1. Savings Map
One of my favorite features with the iRobot app is the map save feature with the option to save up to ten levels. that it Six more than Roborock And Eight more than Ecovacs. In each map, users can add several so-called “clean areas” and “fortified areas”.
2. Stay away from areas
iRobot’s restricted areas version, where users can draw squares or rectangles to indicate restricted areas for the robot, so that it doesn’t roam where it shouldn’t.
It’s something that most brands incorporate into their products. according to for this article On the iRobot website, there is no limit to the number of areas you will draw, but keep in mind that adding too many can get in the way of navigation.
Unfortunately, the iRobot app does not have access to the invisible wall, so there is no way to draw diagonal lines. In most cases, reserved areas are sufficient for most tasks, unless your home has a complex layout.
3. Clean areas
The opposite of clean areas is clean areas. Instead of marking restricted areas, Clean Zones provide quick access to areas that may need more frequent vacuuming.
I like that you can name these areas accordingly to avoid confusion when accessing them through other parts of the app.
4. Label the room
Another convenient feature I would like to highlight is the room naming. After the bot has successfully created the map, you can now add dividers to mark the partitions between rooms, select a name from the list, or use a custom name.
The neat part of this feature is that it is usable with a device like Alexa. So you can say, “Roomba, clean up Benjamin’s room,” and it will clean up that area.
5. Selective room cleaning
Once you set dividers and name rooms, another feature is unlocked – selective room cleaning.
There are several options. Using Alexa or clicking on the “New Job” icon at the top right and check all the areas you want to clean.
The iRobot app also has a scheduling feature where users can automate the cleaning schedule. One difference with Roomba’s premium options (I6/I7/S9) versus the shuffled options (600 and E-series) is that users can schedule multiple sessions per day with a minimum three-hour interval between runs.
Not sure why iRobot added these intervals. I think it’s because of the shorter runtime to give it plenty of time to recharge.
7. No live map
Unfortunately, the iRobot app does not have any live maps. So users can see where the bot is in real time.
It’s been a few years since iRobot released the S9, and I’m not sure if they’ll add this feature, possibly on a newer model, when they’re released.
8. Android Settings
There isn’t much here apart from adjusting the bot’s power settings. You will have these options.
- Detailed cleaning: More comprehensive, with power in the middle setting. Perfect for cleaning carpets or if you need a more thorough cleaning.
- Quiet cleaning: It prioritizes low noise operation and uptime because it uses the lowest power setting.
- Custom: This allows users to customize the power and cleaning lanes to suit their needs. Increasing the power will significantly reduce the operating time. extreme willpower Only give about 45 minutes Usage value and 75 minutes max at the lowest setting.
how strong Roomba S9+ Do you have?
iRobot does not specify official suction numbers with any of its products, while other brands such as Roborock use Pascals as the unit of measurement. For all robotic vacuums I test, I use an anemometer to measure airflow through the main nozzle (or brush).
Here are the full results on all power settings.
- Little: 11.33 cubic feet per minute
- middle: 14.52 cubic feet per minute
- the above: 25 cubic feet per minute
The Roomba S9+ Highest score recorded at 25 CFM At maximum setting for all robot vacuums I’ve tested so far.
The combination of high airflow and wide extractors results in an efficient cleaning robot, which we will consider in detail next.
The high airflow is demonstrated with excellent tones as the S9 captured some of the Top in all areas.
I use ground coffee, Quaker oats, quinoa, pet litter, sand, hair, and fruit rings to check how well the S9 picks up these things.
These are the total results
- Total: 97.93%
- Solid ground: 99.5%
- Sand on the hard floor: 100%
- carpet: 99.25%
- deep cleaning: 93%
Cleaning performance is outstanding with excellent pickup in all categories. You can see the high airflow and excitement in play here, and Eye test confirms These grades were in the cleanest pickup.
hard floor results
- Quaker Oats: 100%
- Cafe floors: 99.2%
- Quinoa: 100%
- pet litter: 98.8%
No issues picking up hard ground as the S9 had an excellent average of 99.3%. It performed worse with heavy quinoa, but one reason for the lower 99% result is the side brush scattering some.
sand on hard floor
Sand is one of the hardest debris to pick up on hard floors. For this experience, I 50 grams of use from him.
Some would say it’s an unreasonable test, but it’s a good measure of how a robot vacuum can clean up this type of debris in areas like this.
The Roomba S9 shoot 100% With the maximum power setting toggled – the best robot vacuums I’ve ever tested. Not surprisingly, Roomba 980 (another high airflow robot) is The only other model to get a perfect score.
Even with the middle setting, the drop Not great at 99.2%.
hair wrap test
Next, we’ll look at how rubber extractors work against strands of hair that are five and seven inches long. I used over a gram per test to see how tangle-resistant these rollers are.
- 5 inch: 81% in the trash; 19% on reels
- 7 inch: 82% in the trash; 18% on reels
Nothing wrapped on the hoods after the five-inch test, but most were on the right cylinder hub.
Some of the threads were coiled onto the light green cylinder with the seven-inch test and others were on the axle.
One advantage of the bristle-free design is that the coils are easy to remove without the use of scissors.
The threads on the axles loosen easily, but it is an area that must be constantly checked as part of the maintenance cycle to keep them operating at an optimum level.
The S9’s D-shape is perfect for edge cleaning, and the results don’t lie. I picked almost every crumb in this test area and most of them are on the Quaker inch crevice.
Low stack results
- Quaker Oats: 100%
- Cafe floors: 96.6%
- Quinoa: 100%
- pet litter: 100%
Again, excellent grades all around. It was worse with ground coffee, but still clean 96.6%Better than most robotic vacuum cleaners, which are close to 90%.
- Quaker Oats: 99.2%
- Cafe floors: 98.2%
- Quinoa: 100%
- pet litter: 100%
Great pickup on a medium pile rug. Surprisingly, it was better to pick up ground coffee on this surface. Not sure why. It could be something random as you cycle over the area enough times to capture a higher percentage. But it’s another indication of the high airflow.
Next, we’ll look at the results of a deep cleaning as I rubbed 100g of sand on a medium pile rug. Cleaning built-in debris is challenging for most robotic vacuum cleaners as these machines lack airflow and agitation to pick up debris under the carpet threads.
The Roomba S9 He excelled in the field and picked up 93% average after three tests. It’s not as good as a high-end stick or upright vacuum, but it’s the best so far out of all the robotic vacuums I’ve tested.
One obvious sign of high airflow is the lack of buildup on the brush roller assembly. I’d like to check this area for any buildup after experiments like this to see how effective the robot was at shoving dirt toward the dust container.
With the S9, there is no loose buildup which is a good sign.
How long will you Roomba S9 He runs?
One of the downsides to using a high-powered motor and double brush is the amount of current it draws. Added juice interrupts uptime, and your S9 will do it Run for only 75 minutes at the lowest level.
Using the maximum setting will lower it further to 45 minutes. The middle setting will be somewhere in between – about 50 to 60 minutes.
Fortunately, this robot has been recharged and resumed – cleaning resumes after recharging to the area it left earlier.
clean base station Adds more autonomy Because it empties the robot’s trash after it is docked to recharge.
How noisy a file Roomba S9+?
One of the downsides to the S9’s powerful engine is the high noise levels. I used an audio meter to check how much noise it makes and here are the results.
- Little: 66.3 dB
- middle: 68.5 dB
- the above: 74.1 dB
What comes in the box?

Availability of spare parts
One advantage of buying a Roomba is the absolute availability of parts. For the S9, there will be no shortage of replacement components. You can buy parts like side brushes, extractors and filters from third-party brands at a lower cost. Even bags are plentiful because the S9 uses the same bag as the more popular I6/I7 variants.
However, the S9 battery is not available on Amazon but only on iRobot website or ebay.
As with all robot vacuums, the S9 needs maintenance to maintain optimal performance for years. If you spend that amount, it makes sense to extend its service life as long as possible, and I’ll give you some tips for that. I have published a comprehensive guide on cleaning Roomba S9. Feel free to check it out for more details on cleaning your Android S9 thoroughly.
- Extractors: These two reels get the most abuse because they are the robot’s primary tool for picking up debris. Dirt and dust will accumulate on them and on the axles. Check it at least once a week (twice if you have a lot of pets) to clean up buildup, especially on axles.
- Side brush: Another area where hair accumulates. Do a visual check once a week for hair buildup on the thorns or base.
- Dustbin and filter: A clean base station automates the task of emptying the trash. But check it at least once a month if it needs a thorough cleaning. This component is washable, but the filter is not covered with paper material. One way to extend the service life of the filter is to tap it against a hard surface to remove dirt stuck in the folds. Replace it every 2-3 months to maintain performance.
- Trolley wheels: This is the little wheel behind the robot. Dirt will stick to the surface and the areas underneath. Pull it out and wipe with a clean, dry microfiber cloth.
- side wheels: Similar to cleaning caster wheels, contaminants will stick to them. Clean it twice a month with a clean cloth.
- Bag inside the clean base station: Dispose of the bag as soon as it is full, and the iRobot app will notify users of it.
- Clean base station: There is not much here. Just keep port access to the bag unobstructed.

5 reasons to buy Roomba S9+
- Great cleaning performance: The Roomba S9 It’s the best cleaning robot vacuum I’ve tested so far, except for nothing. Only the Roomba 980 comes close to it, but this variant doesn’t have the containment and map-saving features of the S9.
- Convenience of automatic discharge: The clean base station adds a convenient crease for emptying the robot’s trash. So there is no need to do this task manually.
- Save maps and smart navigation: This model has the latest navigation technology from iRobot – the smart map fingerprint. Users can save maps, add containments, and choose rooms to clean.
- Great on the rug: If carpet cleaning is a top priority, then the S9 should be on your shortlist because it scored 93% in our deep cleaning tests.
- wide hoods: The wide cleaning path makes the S9 effective at picking up debris.
Verdict: Great cleaning performance, expensive
After testing this robot extensively in the past few days, it Roomba S9+ Proven in cleaning tests to be the best performing robot out of all the brands I’ve tested.
It scored the highest in both the surface and deep cleaning experiments.
While the cleaning performance is great, it is very expensive. This model is one of the most expensive alternatives, and there are some limitations to the functionality, especially the application.
Runtime is also compromised with the powerful engine, and it won’t work as long as the big competitors.
But with recharging and resuming, that shouldn’t be a sticking point. If you can live with the application limitations and high cost, but prioritize cleaning performance, the S9 is the best to do the job.
Roomba S9+: Amazing performance, effective cleaning, but expensive
- Mobility – 94%
- Surface cleaning – 99.58%
- deep cleaning – 93%
- Quality – 97%
- Design – 96%
- Values - 93%
The Roomba S9+ is one of the best (if not the best) robot vacuum cleaners available. Based on tests, it scored the highest overall cleaning performance score. Eye tests validate these numbers as the S9 picked up debris clean on hard floors and carpets. But there are some drawbacks of this product, which are short operating time, lack of some application features, and very high cost. If you don’t mind paying a premium for a robot vacuum to clean your floors well and don’t care about issues, the S9+ is worth considering.
