Ned O.

Intelligent, self-emptying robot vacuum

The iRobot Roomba s9+ cleans hard floors and carpets with a careful eye, precise navigation, and super-powerful suction. It's got smart features that let it map your home and keep out of danger — and out of your way.  And since it's self-emptying, you don't even have to think about vacuuming for months at a time.

Intelligent, self-emptying robot vacuum

iRobot Roomba J7

The Roomba s9+ literally works around you, learning your home's layout, your stuff, and your schedule.

The iRobot Roomba s9+ cleans hard floors and carpets with a careful eye, precise navigation, and super-powerful suction. It's got smart features that let it map your home and keep out of danger — and out of your way.  And since it's self-emptying, you don't even have to think about vacuuming for months at a time.

iRobot has been making robots that explore space, the ocean floor, and more for over 30 years. That means that with this Roomba you'll be getting state-of-the-art robot vacuum technology.

Advanced navigation

The s9+ navigates in neat rows, going under and around your furniture and mapping as it goes. Its vSLAM® navigation captures over 230,400 data points per second to as it learns your home over time.

Its selectable Careful Drive mode uses 3D sensor technology to smartly avoid and clean around objects taller than 2.5cm. It can also see which areas in your home are the dirtiest and give them more attention. And its cliff-detect feature keeps it from falling down staircases and other steep drop-offs.

App and voice control

You'll control the s9+ with the iRobot Home app for Android™ and iOS®. It lets you set up cleaning routines, clean specific rooms, create keep-out zones, customize zones within rooms, and more.  

The s9+ can keep out of your way by starting its cleaning routine after you've left the house, if you enable this location-based feature in the app. The app can also make seasonal cleaning schedule recommendations, like during cat and dog shedding season.

You can also control the vacuum with your voice using Google Assistant and Amazon Alexa devices (sold separately).

Top-of-the-line three-stage cleaning

The s9+'s Perfect Edge technology uses advanced sensors to optimize deep cleaning in corners and along edges. Its edge-sweeping brush pulls dirt and dust toward its rubber roller brushes and powerful suction — 40 times stronger than the Roomba 600 series.

Its patented roller brushes — 30% wider than in other Roomba models — are designed to avoid tangles from hair. They really pry into your carpet so the vacuum can suck up embedded sand and other tenacious dirt. 

Automatic dirt disposal and recharge

This Roomba comes with a Clean Base self-emptying and charging station that can handle up to 60 days' worth of the stuff your s9+ vacuums up. It sucks the dustbin clean when the vacuum docks to charge, storing the dirt in an internal dust-free bag.

Its recharge and resume feature automatically sends it back to its base to charge when it senses a low battery, then back out to pick up where it left off vacuuming.

After vacuuming

If you want, you can add a Braava Jet m6 smart mop (sold separately) that will start working the moment the s9+ finishes.  

You can hand-wash the vacuum's dustbin using warm water — just remember to take the filter out before you wash it, and make sure it's dry before you put the filter back in.

More details on the iRobot Roomba S9+ with Clean Base®

Product Research


Overview: The Roomba® s9+ (s955020) from iRobot is a Wi-Fi connected, self-emptying robot vacuum. With Roomba's 3-Stage Cleaning System and the most powerful suction to date, the s9+ automatically cleans the rooms you want when you want. iRobot's vSLAM Navigation captures over 230,400 data points per second to help the robot vacuum learns the layout of each room. The iRobot Home App can customize your cleaning schedule, while voice assistants Amazon Alexa and Google Assistant let you start cleaning with a simple voice command. The s9+ comes with the Clean Base Automatic Dirt Disposal and charging station, two dirt disposal bags, a spare High-Efficiency Filter and Edge-Sweeping Brush.

Cleaning Power: The Roomba s9+ cleans your floors effectively with its premium 3-Stage Cleaning System. Dual Multi-surface Rubber Brushes, one loosens the dirt while the other lifts, help tackle tough dirt and grime on any surface. The brushes are 30% wider than the Roomba 600-series for higher efficiency. The Roomba automatically adjusts for hard surfaces or carpet, so there's no need to change the settings. The rubber brushes stay in contact with wood, tile, and carpet to pick up the dirt more efficiently than bristles. In addition, they avoid tangles from human and pet hair, so there's less maintenance. A rotating Edge-Sweeping Brush sweeps dirt, pet hair, and dust from along the wall edges and in corners. The s9+'s self-adjusting suction, 40x more powerful than the Roomba 600 series, pulls in the dirt and debris from all types of surfaces. While it cleans, a High-Efficiency Filter captures 99% of pollen, mold, dust mites, and other allergens. The dirt and debris are captured in a removable bin, which is automatically emptied into the included Clean Base. The bin can be hand-rinsed with water.

PerfectEdge® Technology: The s9+'s PerfectEdge® Technology efficiently cleans your floors from edge-to-edge. Advanced sensors detect and hugs the walls while the specially-designed rotating Corner Brush reaches beyond the front and side edges to clean along the wall and into corners.

Clean Base®: The s9+ comes with the Clean Base Automatic Dirt Disposal and charging station where the vacuum charges its battery and stores when not in use. At the end of a job, or when the removable bin becomes full, Roomba returns to the Clean Base where the contents of the dirt bin are automatically emptied into the base. You can also empty the bin manually, if desired, from the vacuum's top panel. The large disposable bag allows the s9+ to empty itself for up to 60 days. When the bag becomes full (indicated by a glowing red LED on the front panel), simply remove the self-sealing bag, dispose into the trash can, and put a new one in the base. The Clean Base should be placed in an area with no obstacles within 1.5 feet to either side, or within 4 feet in front. To prevent the robot from falling downstairs, Clean Base should be placed at least 4 feet from stairs. The base plugs into an AC outlet via its removable 6' power cord.

Imprint® Smart Mapping: Roomba s9+ uses powerful Imprint® Smart Mapping technology that learns your home's layout and creates Smart Maps of each room. During the initial non-cleaning Mapping Run, the robot vacuum travels in straight lines back and forth throughout the room, using its built-in camera to learn where the furniture, obstacles, and stairs are located. It also learns the boundaries for each room. It may require several Mapping Runs to become totally efficient in cleaning your home. The s9+ offers cleaning of individual rooms, and even specific areas within a room. With Targeted Room Cleaning, you can instruct Roomba to clean specific rooms on demand or on a personalized schedule. Targeted Area Cleaning lets you create Clean Zones (under the dining room table) and Keep Out Zones (near the pet's food and water bowls). These targeted zones can be recalled in the iRobot Home app, or by voice command with Amazon Alexa or Google Assistant.

Reactive Sensor Technology: The robot vacuum is equipped with numerous sensors to help it maneuver the natural obtacles in your home while it cleans. The front of the unit has the iAdapt Localization camera that detects new objects in its path. If the unit bumps into a chair leg or wall, the impact is softened by the smart bumper on the front, and a sensor causes it to turn away from the obstacle. Four "cliff sensors" along the front and sides let the vacuum know that it is nearing a dropoff, such as stairs or a balcony, and the unit will back away from the ledge. Wall Follow Sensors allow the Roomba to follow the path of the wall as it cleans. Other sensors also detect the clearance under chairs and couches so the vacuum doesn't get hung up. Dirt Detect sensors also recognize areas of your floors that need more attention, and those that don't.

Onboard Controls: The s9+ has three onboard controls:

  • Clean/Power: The large Clean/Power button wakes up the vacuum to begin cleaning.
  • Home: The Home button instructs the vacuum to stop cleaning and return to the Clean Base.
  • Spot Clean: The Spot Clean button allows Roomba to intensely clean a localized area by spiraling outward to a diameter of about three feet and then spiraling inward to the spot where it began.

Regular Maintenance: Periodically, the Roomba needs regular care and cleaning to maintain optimum performance. The dirt bin self-empties after each cleaning, but it should be rinsed out with water as needed. The High-Efficiency Filter should be gently cleaned once a week--more frequently if you have pets. It should be replaced every couple of months. The Full Bin sensor and Rear Caster Wheel need cleaning every two weeks. The Edge-Sweeping and Multi-Surface brushes require cleaning every month, and replaced every 12 months. The camera window, sensors, and charging contacts should be wiped clean once a month.

Power: The Roomba s9+ is powered by a user-replaceable Lithium-ion rechargeable battery. The battery fully charges in approximately 2 hours while docked in the Clean Base. Initially, the battery should be charged at least 3 hours. A fully charged battery lasts approximately 120 minutes. The s9+ supports Smart Recharge and Resume. When the battery is running low, the vacuum returns to the charging station to recharge enough to finish the job, then picks up where it left off, until the task is complete. The battery should last up to 400 charge cycles before being replaced with a new battery obtained from the manufacturer.

Wi-Fi: The s9+ connects to your home's 2.4 GHz or 5 GHz Wi-Fi network. You can control it with the iRobot Home App on your smartphone or tablet.

iRobot Home App: The iRobot Home app is essential to the operation of the s9+. With the app loaded to your smartphone or tablet, you can choose when and where to clean, and create custom cleaning schedules. When cleaning is complete, you can view a Cleaning Report in the app, showing the date and time of the cleaning job, the length/duration, and total area (square feet) cleaned. The app learns your scheduling preferences, and can even suggest extra cleanings during peak pollen season, or when your pets typically shed the most. iRobot Genius Software updates are available through the app, and can be downloaded to the Roomba. These updates can add new features, as well as fix bugs, and keep it up to date. The iRobot Home app works with iPhone and iPod touch running iOS 13.0 or later, and with iPad with iPadOS 13.0 or later. It is also compatible with Android devices (version varies with device).

Voice Assistants: The s9+ can be operated by voice command through your favorite Voice Assistant. You can ask Amazon Alexa or Google Assistant to ask Roomba to start cleaning, and the robot vacuum will begin a cleaning cycle.

What is the suction power?
[ Cj 1111  Nov 02, 2022 ]
1 answer
iRobot does not list a specific measurement for the suction power of the S9+ but do state it being 40x more powerful than the Roomba 600 series and having 4x the suction power of I and J series.
[ ARIELLE H  Nov 03, 2022 ]  Staff
Does this unit use water cleaning in kitchen areas? I need sticky kitchen floors washed does this have the ability to wash with water?
[ Kathy  Jul 12, 2022 ]
1 answer
This product functions only as a vacuum. It does not mop. The iRobot Braava Jet M6 is a separate system that mops the floors. The Braava can be programmed to begin mopping after a Roomba has finished vacuuming. Here's a link to the Braava Jet M6:
