Introduction to the Roomba S9 and I7
The S9 and I7 brought in ii significant upgrades in the Roomba product line.
With the I7, it was the first Roomba with the "automated dirt disposal organization" where iRobot has a second vacuum inside the charging dock that empties the bin afterward it returns from a cleaning bike. And then in the
Roomba S9 , they ditched the round design and followed Neato's D-shape structure.
Making this switch gives the
Having a wider castor improves its edge cleaning over the I7. The S9 too has the "Clean Base" dock that automatically empties the grit bin.
Of course, these upgrades volition come up at a premium.
Fortunately, iRobot gives yous the pick to buy their products with or without the cocky-elimination organization.
Folks who want to save coin tin opt for the non-plus variant that simply comes with the robot.
Other than the add-on of the clean base of operations dock, both options are like.
The clean base station can be bought separately and comes with a special dust bin for this purpose. Information technology is a significant upgrade that will toll several hundred dollars.
So it's better to make upwards your listen before purchasing, as buying the upgrade separately will entail a college cost.
Advantages of the Roomba S9
- Better at Edge Cleaning: The new D-shape design and the wider brush enable the S9 to perform meliorate at cleaning edges and corners. Tests show that information technology does ameliorate at such.
- Slower Spinning Side Brush: Another comeback that enables the S9 to clean improve is the side brush spinning slower. The fast-spinning side brush on the I7 and earlier models tend to scatter debris more.
- 30% Wider Extractors: Having wider extractors allows this robot to comprehend more basis and avoid tangles when cleaning pilus (pet or human).
- More power: The
Roomba S9 is the most powerful robot vacuum to appointment, with airflow producing 22 CFM. - Better on Hard Floors: The strong airflow on low power and the better-designed side castor give the S9 excellent performance on hard floors.
- Will Deep Make clean on Carpet Meliorate: This model is ane of a select few robotic vacuums that can pick up more than 90% of the sand on medium-pile carpets.
Potential issues
- Insanely Expensive: To give y'all some perspective on how expensive this robot is. It costs more than iii loftier-end Dyson upright vacuums! That's crazy!
- Complaints near Software Issues: There are complaints most buggy software that affects navigation (e.g., gets stuck or lost).
Like the S9, the I7 also has ii versions – the "plus" option with the make clean base of operations station and the entry-level pick without it.
This model is the outset Roomba with an automated cleaning station that makes information technology truly autonomous.
As you'll read in the reviews, the older option, iRobot, has ironed out the software bugs.
It retains the round shape that previous Roomba robots have. One reason why iRobot stuck with this design for its unabridged existence is its agility. Navigating around furniture won't be an consequence with its unlimited turning radium.
Advantages of the Roomba I7
- Less Expensive Alternative: The I7 is a few hundred dollars cheaper than the S9. Without the clean base dock, it's a much better deal.
- Better at Picking Upwards Large $.25 of Dirt: This model does a better task of picking upwards Cheerios-sized dirt. I reason could be that the extractors are higher up. However, it comes at the price of deep cleaning performance.
- Democratic Robot for Less: The Roomba I7+ provides the aforementioned hands-free convenience for much less than the S9+. It doesn't have the bells and whistles of the S9 and won't deep clean every bit well.
- An Excellent Pick for Pet Owners: This robot has a fully-sealed organisation that keeps fine dust, dander, and other types of allergens at bay inside the bin. It is too excellent at picking upwardly pet litter and hair.
Potential issues
- Even so Expensive: Despite being less expensive, the I7 is notwithstanding more expensive than nearly other high-stop robotic vacuums.
- Won't Deep Clean Every bit Well: The less powerful motor and narrower extractors won't pick up embedded dirt as well as the S9.
- More tangles: Long hair will wrap up around the extractors and their axles. Make certain to regularly check the main castor for tangles if someone in your home has long hair.
Both robots have the same motor, navigation system, and brush, and then wait the same performance.
The difference between the plus and not-plus versions is the upkeep.
There's less babysitting with the "+" version since a 2nd vacuum in the dock will empty the bin. Within the clean base station is a purse that can concur upward to "30 bins of dirt" according to iRobot.
Then it'due south a truly hands-gratis device that will keep the house clean with minimal babysitting.
Of course, there'due south some maintenance work involved with cleaning the brush gyre and filters (more on that in a afterwards section).
But the signal is the Roomba I7 and S9 are the offset truly automated robots smart plenty to make clean a whole level without any human involvement.
Roomba S9 Blueprint
The
It'south now has a square front with a round backend – a D-shape pattern like to the Neato D7.
I'yard guessing iRobot did this to help their robots friction match the outstanding performance of their chief competitor.
In the middle is a gold disc that is the cover for the larger grit cup.
Behind the disc is the photographic camera sensor that the S9 uses to map its location.
It has a matte charcoal finish that I like because it resists clay amend than something glossy.
Interface and Controls
The S9's new shape necessitates a change in interface.
The three buttons are no in a new position at the upper right, unlike the previous version in the centre.
It'southward the same three buttons – dwelling house, clean, and spot. The rest of the features are accessible through the iRobot Dwelling house App that yous can download through the Google Play Shop or Apple's App Store.
This Roomba retains the minimalistic simplicity of the older models that makes their products and then popular.
Roomba I7 Design
The Roomba I7 retains the circular design seen in earlier versions.
Correct in the centre is the camera that the I7 uses for mapping purposes. The IR sensor on the front helps it track the charging base's location when it needs to dock.
This model has a glossy, 2-tone charcoal and gray end.
I'thou not a big fan of glossy finishes because these are prone to fingerprints, but that's just my opinion.
Interface and Controls
The I7 has only had iii buttons – home, make clean, and spot.
Since this model has Alexa and an app, it does not need annihilation more than than these equally all of the functions are attainable through the software y'all can download.
It's a simple design that takes away the clutter. You can use voice or schedule the robot through the app to clean.
How do the Roomba S9 and I7 clean?
There are several layers to unpack to understand how these robots make clean.
It'south essential to sympathise how information technology works so that you tin can maximize its functionality.
The first thing to look at is navigation.
These two robots take the same camera-based navigation that'south paired with iRobot'southward new "Imprint Mapping Engineering."
This term means the maps that the robot creates through its various sensors are saved in iRobot's cloud servers.
Here's a quick look at how the
Having this feature allows these robots to program a more efficient route in subsequent cleaning cycles considering it has the maps saved.
Information technology also gives these machines the power to make clean a specific room at a scheduled time.
This feature is usable with Alexa, and so at that place'southward an selection to use voice and can say, "Roomba, go make clean the master's bedchamber."
Both also have what iRobot calls "preparation runs," where the robot goes around the firm with the vacuum motor shut off.
The purpose of this characteristic is for the robot to gather data most the dwelling'due south interior layout.
Since the motor is off, it volition be able to scan your whole home without having to recharge.
Make clean base charging station
If you become the "plus" option, both models will come up with the "Make clean Base" charging station that automatically recharges and empties the dust bin.
It's non an original blueprint, just the Roomba I7 is the first robot vacuum bachelor commercially with this feature.
The auto-empty system that iRobot developed is very convenient because it takes the bin elimination chore out of the equation.
In that location's no need to touch the robot for weeks on finish, except for maintenance tasks such as checking the filters or brushes for any droppings build-up.
This device and smart mapping technology give consumers many options, such equally cleaning certain areas on specific days.
When the battery runs low, the robot will dock, recharge and then resume where information technology left off, making information technology possible for the
A quick wait underneath
Side by side, allow's look underneath these robots to come across how information technology picks up dirt.
Here'southward how the
Roomba S9
One look at the latest Roomba shows us the radical change that iRobot did.
Gone are the narrow extractors and the long, three-pronged side castor.
The main extractors are at present in front of the robot with a shorter side castor with more than prongs.
This castor spins slower, and then it does non kicking around clay every bit much as the I7 or earlier Roomba models.
The square front of the
iRobot also adds a new 3D time-of-flight sensor at the front bumper that helps it navigate effectually tight areas.
This sensor besides helps the S9 "hug" the walls better, meaning information technology'll go shut to clean these areas better than whatever Roomba robots earlier information technology.
Roomba I7
The Roomba I7 retains the round shape of its predecessors and has the same brush layout.
The narrower extractors are located in the center behind the side castor flanked past the two self-adjusting wheels.
Having a shorter cleaning path means it will take a fleck longer to make clean.
The primary side brush has iii prongs that spin at a more rapid pace than the S9, which tends to besprinkle dirt around more on difficult surfaces.
Despite this flaw, the I7 cleans quite well on surfaces like hardwood.
Grit Loving cup Comparing
Here'southward the Roomba I7 dock.
There isn't much of a divergence betwixt these two robots regarding how much dirt they can hold.
The S9 with its redesigned bin that loads from the top can agree up to 0.4 liters while the I7 that slides out from the back has a 0.3-liter capacity.
If you decide to get the "plus" version, the size difference volition exist irrelevant since the make clean base of operations dock automatically empties it freeing you up from this task.
How much ability do the Roomba S9 and I7 have?
A critical measure of how well a robotic vacuum will make clean is the airflow.
Unfortunately, manufacturers don't have a universal measure to gauge power, so let's expect at the airflow numbers for this department.
I used an anemometer to measure airflow at the nozzle where the brush roll is located.
Take notation that at that place is e'er a margin for error for these types of tests, only it'due south a good comparison without whatever biases.
For the
The S9 on its high power setting produces up to 22 CFM of airflow and 8 CFM on low while the I7 has 17 CFM on its rug boost mode (or high setting) and less than vii CFM on low.
Note that the I7′ only has i power setting, the car mode, which automatically adjusts suction based on the surface and the amount of dirt it detects.
Roomba S9 vs. I7: Cleaning Performance
Permit's at present look at how well these robots make clean.
When information technology comes to picking upward surface dirt, there isn't much difference betwixt the S9 and the I7.
Roomba I7
I of the most pregnant bug with the I7 is its lack of airflow in its depression ability setting. For some strange reason, it's lower than the airflow numbers on the Roomba 690 at eight.2 CFM.
Difficult floor cleaning
The I7 does a superb job at cleaning messes like this on the hardwood.
It adversely affects the I7'due south performance, specially at cleaning sand, where it did not do as well every bit the
If yous alive almost the beach and constantly have to bargain with sand, the S9 will be the ameliorate selection.
Other than sand, it could option up all of the dirt in cleaning tests done – much meliorate than the Roomba 980.
Some other potential result would be cleaning long strands of hair. In tests, the I7 simply picked up 25% of the one gram of seven-inch human hair. Most of information technology is either wrapped around the axles or the extractors themselves.
Curt pet pilus won't exist much of an event, though.
The longer pronged brushes spin rapidly, which can tosses dirt around more, but the I7 will eventually pick information technology up.
Carpet cleaning
The I7 did well in carpet cleaning tests with the fast-spinning side brush a non-issue on this surface.
One advantage over the S9 is its ability to choice up larger bits of debris without the crunching dissonance that the S9 has.
Information technology won't deep clean also as the S9 because of the less powerful motor. In tests, the I7 was able to pick up only 79% of the 100 grams of sand on medium-pile carpet. Recollect that this score was one of the all-time before the
Roomba S9 came out.
Roomba S9
The S9, with its more stiff motor, does offering advantages over the I7 in specific areas, which we'll look at in this section.
Hard floor cleaning
When cleaning regular household dirt such as grit, dander, cheerios, etc., the S9 and I7 produce similar results. Both accept enough power for such a task.
However, the S9, with its ability upgrade, does a much better task when information technology comes to stuff like sand.
The stronger airflow and the wider extractors will selection upward more sand.
Information technology is proven in cleaning tests where the S9 picked up nearly everything while leaving trace bits on the corners and edges.
The redesigned side castor and slower rotation speed don't scatter clay as much with shorter arms and more than prongs. It does amend at funneling information technology towards the primary extractors.
Carpet cleaning
There isn't much of a difference between the S9 and I7 in terms of surface cleaning.
The benefit of wider brushes and a more than powerful motor is seen in deep cleaning tests where the S9 got a very impressive score of 94.five% (boilerplate of ii tests) when cleaning 100 grams of embedded sand on medium-pile carpet.
You lot'll hear a crunching sound when it tackles extra-big stuff similar Fruit loops, but it picks them up nonetheless.
Notable app features
The
Well-nigh of these features are bachelor for both models.
- Go along Out Zones: It'due south Roomba'southward version of Neato'south no-go zones that human activity as a virtual wall that prevent the robot from going into "off-limit" areas. Initially, this feature is but available with the S9, but I7 users will benefit from it in the latest roll-out.
- Advanced Scheduled Cleaning: It is at present possible to schedule the robot to make clean a specific room on a particular day. For example, on Mondays, Wednesdays, and Fridays, the robot tin can clean the living room, and on Tuesdays, it can tidy up the master's sleeping room.
- Imprint Smart Mapping: This technology is the robot'southward software'south ability to save maps of an entire level of the home (upwards to 10). The robot can apply this information to plan a improve road and for its zone cleaning feature.
- Zone Cleaning: It works well with the scheduling feature that tells the robot to clean specific rooms or areas.
Roomba S9 vs. I7: Maintenance and Running Costs
Like any other vacuum, in that location is a certain level of upkeep to keep it in tiptop shape.
Realize that these machines accept various filters, sensors, and brushes that demand periodic maintenance.
The corporeality of coin spent will depend on whether yous'll go the "plus" or the basic version.
Loftier-Efficiency Filter [once or twice a month]
Roomba S9 Filter
Roomba I7 Filter
iRobot recommends replacing it in one case every 1 to two months. Make sure to check it at to the lowest degree once a week for whatever dust build-up.
You can use a handheld vacuum or a stick vacuum that morphs into a handle such as the Tineco Pure One S12 or Dyson Five8 to remove any stuck debris and extend intervals by a week or and then.
These filters are not washable, and so please avoid doing and then to prevent voiding the warranty.
Make clean Base Bags [depends]
Roomba S9 and I7 Clean Base Bags
Buying these numberless is but applicable if yous purchase the "plus" variant with the Clean Base of operations station. Intervals will depend on how ofttimes yous run the robot and the type of clay information technology cleans.
Pet owners apparently will have to supplant it more oftentimes because pet hair and dander take up a lot of infinite.
The good news in that location is a myriad of brands that sell bags for the S9 and I7. Both options apply the same type of bag, so there's less confusion.
Side Castor [depends]
Roomba S9 Side Brush
Roomba I7 Side Brush
Check the side castor for any hair that wraps effectually the base. The side brush of the S9 spins slower, so it won't be less wear than the I7 side brush.
Rubber Extractors [depends]
Roomba S9 Extractors
Roomba I7 Extractors
The prophylactic extractors on the S9 and I7 will last longer than a more traditional brush in the 675 or 690.
Replacement parts are widely available just in case it wears out. As of now, replacement S9 extractors still aren't available for sale, but there will be vendors selling these parts soon.
While iRobot may advertise it as maintenance-free, at that place is yet a need to check it, especially at the axles where hair and dust can build up.
Replacement Battery [depends]
The Li-Ion batteries inside these robots volition last at least a few years. These parts are amend built, and previous versions use a Ni-Cad bombardment.
Another reward of buying a Roomba over other brands is the availability of parts such as this. Roomba provides like shooting fish in a barrel access to the battery using simple tools.
With the I7 and S9 beingness new, in that location aren't many options available, but soon.
Total Bin Sensor [every 2 weeks]
Inside the dirt, the bin is a sensor that detects and fires a betoken to the app if it is full. Clean this role at to the lowest degree one time every two weeks.
Castor Bicycle [depends]
One function that takes a lot of abuse is the castor wheel. This part is responsible for steering the robot. The I7's castor wheel is at the front, while the S9 sits at the rear portion.
iRobot recommends replacing it once a twelvemonth, but I believe it volition final longer with proper maintenance.
Make clean information technology regularly with a microfiber towel. And so dirt does not build up that could impairment the bearings.
Sensors
Around the robot is a bevy of sensors that help it move around furniture and pinpoint its exact location.
If any of these sensors get dirty, it compromises how these robots navigate. Utilize a clean microfiber towel to wipe the main camera sensor on summit and cotton buds for the tiny sensors around and underneath it.

The size difference between the Roomba I7 vs. S9
The
And then the S9 has a lower profile and will become underneath more furniture better than the I7. The narrower contour helps it fit betwixt furniture legs with less risk of getting stuck.
How long do the Roomba S9 and I7 run?
The
Roomba S9 with its larger cell Li-ion batteries volition run for upwards to 120 minutes on the low setting and 49 minutes on high. The Roomba I7 only has one power setting and it will run for up to 75 minutes.
On a side annotation, these numbers only matter if yous're getting the base version without the clean base of operations station. The "plus" version is almost a non-factor considering both variants have the recharge and resume feature.
Racket level comparison
Engineers did a tremendous job with muffling the racket levels of the I7 and S9 despite the crash-land in power.
The I7 simply produces 62 decibels, and the S9 tops out at 64 decibels. The divergence is negligible, to be honest.

Spec Comparison of the Roomba I7 vs. S9
Which of the ii offers the amend value?
There's no uncertainty in my mind that the Roomba I7 and S9 are ii of the all-time robotic vacuums available correct now when you lot combine their efficiency and outright pickup-ability.
I understand that the toll deviation is substantial, with the S9 chop-chop existence a few hundred bucks more expensive.
So is the premium worth it?
Let's look at four reasons why you should consider the Roomba S9 :
- Amend at Cleaning Embedded Dirt: The wider extractors and extra power make the S9 an fantabulous choice for folks looking for something that can deep clean rug. There'southward no other robot bachelor right now, bated from the Neato D7, that can come close to the S9 cleaning embedded dirt.
- Superior Edge Cleaning: Some other benefit of the square frontend is its ability to make clean edges better. It'southward got a new sensor inside the bumper that makes information technology hug the walls and better navigate small spaces.
- Does Not Tangle as Much: The larger beater bar resists tangles from longer hair strands meliorate than the I7. If you alive with someone who has long pilus, y'all may desire to call back of getting this over the I7.
- Better At Picking Upwards Sand: People who alive near sandy areas will benefit from the ability of the S9 to do then more efficiently.

Now, let's look at 3 reasons why you should consider the Roomba I7:
- Less Expensive: The Roomba I7 is a few hundred dollars cheaper than the S9. If the cost is a primary concern, then the choice is obvious.
- Same Efficient Navigation: Aside from the bumper sensor on the S9, the I7 has the aforementioned efficient navigation pattern every bit the S9. It has the same recharge and resumes feature and the Smart Banner Mapping organization that saves maps in the cloud.
- Excellent at Surface Dirt: The i advantage the S9 has over the I7 is its ability to deep clean carpet. Aside from that, the I7 and S9 are near identical when it comes to surface debris pick up (apart from sand). If deep cleaning is not a business organization, then save a few hundred bucks with the I7.
Click here to check the latest toll of the Roomba S9 on Amazon and Walmart.
To summarize, here are the differences between the Roomba I7 vs. S9:
- Design: The S9 is the first Roomba to have the square shape front fit in the wider extractors and new side castor. The I7 retains the round shape of the previous generation 980.
- Runs longer: The S9 will run for up to 120 minutes on eco mode, while the I7 runs for upwards to 75 minutes (only one power setting).
- Side brush: The S9 side brush has a smaller diameter with more tentacles, and it spins at a slower footstep than the I7. This prevents dirt from scattering on hard surfaces.
- Cost: Buying the S9+ with the clean base station will be equivalent to buying more than iii Dyson uprights. It is expensive. The I7, especially the non-plus version, is way cheaper.
- Edge cleaning: The wide extractors and square forepart of the S9 allows it to make clean edges amend.
