For anyone serious about automated home cleaning, the promise of a truly hands-off experience often falls short with lesser robots. I’ve tested numerous models that get lost, avoid dark rugs, or leave entire sections of a room untouched. This is precisely why the Roomba s9+ demands attention; it represents iRobot’s flagship effort to conquer these very challenges with advanced navigation and powerful suction. My in-depth evaluation of the Roomba s9+: In-Detail Review and Performance reveals whether its premium engineering translates into a tangible difference in daily cleanliness and convenience.
The core benefit you get with this system is a significant reduction in manual vacuuming. It’s designed not just to clean, but to learn your home’s layout for methodical, room-by-room cleaning and to empty its own bin for weeks at a time. After putting it through its paces in a home with a mix of hardwood, tile, and medium-pile rugs, alongside the typical debris of a busy household, I have a clear picture of where it excels and where it might not meet every expectation.
Roomba s9+: In-Detail Review and Performance – Quick Verdict
After extensive testing, the Roomba s9+ stands out as a powerhouse for deep cleaning, particularly on carpets and in tackling pet hair. Its unique D-shaped design is a game-changer for corner cleaning, a common weakness in round robots. The Clean Base Automatic Dirt Disposal is the crown jewel of the experience, allowing for weeks of touch-free cleaning. Navigation via iRobot’s PerfectEdge and Imprint Smart Mapping is generally precise, enabling efficient room-by-room cleaning and reliable keep-out zones.
However, it’s not a perfect solution for every home. Its performance is best appreciated in environments with multiple rooms, carpets, and pets, where its superior suction and hair-management systems can truly shine. For smaller, single-level apartments with mostly hard floors, its advanced features might be overkill. Based on my experience and widespread user feedback, here’s a quick breakdown of its strengths and weaknesses.
Pros
- Exceptional suction power, especially on carpets and for embedded pet hair.
- The Clean Base Automatic Dirt Disposal is a revolutionary convenience.
- D-shaped design provides superior corner and edge cleaning.
- Advanced navigation and smart mapping allow for efficient, customizable cleaning.
Cons
- The navigation system can be methodical but sometimes slower than less advanced models.
- Can be louder on hard floor surfaces compared to other premium robots.
- Its high-end features come with a premium positioning that may not suit all budgets.

Roomba s9+: In-Detail Review and Performance Overview
The Roomba s9+ is iRobot’s top-of-the-line robot vacuum and mopping system, designed as a comprehensive cleaning solution for the modern smart home. Its primary purpose is to automate the entire vacuuming process, from navigation and deep cleaning to bin emptying. The system includes the s9 robot vacuum and the Clean Base Automatic Dirt Disposal station, which holds up to 60 days of dirt and debris, depending on your home’s conditions. It also pairs with the Braava jet m6 robot mop for a full sweep-and-mop routine, though my testing focused primarily on its vacuuming capabilities.
This product is designed for homeowners who prioritize deep cleaning and maximum convenience. It’s an ideal fit for households with pets, as its anti-tangle brush system and powerful suction are engineered to handle copious amounts of fur. It also suits tech-savvy users who appreciate detailed control through the iRobot HOME app, including the ability to set specific cleaning schedules for individual rooms, create keep-out zones, and view detailed cleaning maps. Key specifications include a High-Efficiency Filter that captures 99% of allergens like pollen and mold, a 3-Stage Cleaning System, and compatibility with Alexa and Google Assistant for voice control.

Key Features & Performance
During my testing, I focused on how the Roomba s9+’s flagship features translate into real-world performance. I assessed its ability to navigate a complex layout, its effectiveness on different floor types, its handling of pet hair, and the overall impact of the self-emptying base on daily life.
Corner and Edge Cleaning with the D-Shaped Design
This is arguably the most distinctive physical feature of the s9+. Unlike every other round Roomba, the s9+ is designed with a flat edge, allowing it to get significantly closer to walls and into corners. In practice, this makes a noticeable difference. In my testing, it left far less debris in the corners of rooms compared to round models. The PerfectEdge technology actively spins the side brush when it’s navigating along a wall, sweeping debris directly into its path. For baseboards and the tight spaces behind furniture legs, this design is genuinely effective and delivers a level of thoroughness that round robots simply cannot match.
Powerful Suction and Carpet Performance
iRobot claims the s9+ offers 40 times the suction power of their 600 series models. While I can’t verify that exact multiplier, I can confirm its performance on carpets is exceptional. On a medium-pile rug where my previous robot would leave behind fine sand and embedded pet hair, the s9+ made a visible difference in just one pass. It automatically increases suction power when it transitions from a hard floor to a carpet, which you can clearly hear. It tackled cereal crumbs, tracked-in dirt, and a significant amount of dog hair with ease. For homes with a lot of carpeting, this is where the s9+ justifies its position as a premium cleaner.
Advanced Navigation and Smart Mapping
p>The s9+ uses iRobot’s vSLAM technology to navigate and create a detailed Imprint Smart Map of your home. The first few runs are a learning process as it explores and maps the space. Once the map is saved, the experience changes completely. You can label rooms, send the robot to clean just the kitchen and living room, or set a schedule for the bedrooms only. I found the Keep-Out Zones to be incredibly reliable; I was able to draw a virtual line to prevent it from bothering with a dog water bowl or a pile of charging cables. While its pathing can be more methodical and sometimes slower than a random-bounce robot, the efficiency and control gained through smart mapping are substantial benefits for multi-room homes.
The Clean Base Automatic Dirt Disposal
This feature is the ultimate convenience and the heart of the “hands-off” promise. After each scheduled cleaning, the Roomba s9+ returns to its base, and you hear a powerful, albeit loud, suction as the base empties the robot’s bin into a sealed, allergen-lock bag. This means you can go for weeks, or even months, without physically interacting with the vacuum. For allergy sufferers, this is a major advantage, as you’re not exposed to dust and dander when emptying the bin. In my testing over several weeks, the base successfully emptied the bin every time, and the bag capacity is generous. It fundamentally changes the relationship with your robot vacuum from being a daily chore to a background appliance.

Final Verdict
After a thorough evaluation, the Roomba s9+ earns a strong recommendation, but with a clear understanding of its ideal user. It is an investment in convenience and deep-cleaning performance, particularly for specific home environments. Its strengths are so pronounced in certain areas that they can completely redefine your cleaning routine, while its few drawbacks are important to consider before making a decision.
Here is a detailed breakdown of its advantages and limitations based on my hands-on testing:
Pros
- Unmatched Carpet Cleaning: The suction power is genuinely top-tier. It pulls embedded dirt and pet hair from carpets in a way that few other robot vacuums can, leaving a noticeably cleaner surface.
- Ultimate Convenience: The Clean Base Automatic Dirt Disposal is a transformative feature. The ability to run daily cleanings for weeks without touching the robot is the pinnacle of automated cleaning.
- Superior Corner Cleaning: The D-shaped design is not a gimmick. It consistently cleans corners and along edges more effectively than any round robot I’ve used.
- Intelligent Navigation: The smart mapping and room-select features provide a level of control and efficiency that makes the robot feel like a truly smart appliance, not just a random cleaner.
- Excellent with Pet Hair: The combination of powerful suction and the anti-tangle rubber extractors means it handles pet hair brilliantly, both on floors and inside the robot, preventing jams.
Cons
- Methodical Navigation Speed: While efficient, its careful navigation can be slower than some competitors. It prioritizes thoroughness over speed, which can be a minor frustration if you need a quick clean.
- Noise Level: On its highest power setting, especially on hard floors, it is noticeably louder than other premium models. The Clean Base emptying process is also quite loud, though it only lasts for about 15 seconds.
- Premium Positioning: It is positioned at the very top of the market, which means its advanced features come at a cost that may not be justifiable for all homes or budgets.
I recommend the Roomba s9+ wholeheartedly for homeowners with multiple rooms, a significant amount of carpeting, and pets. If your priority is deep-cleaning performance and the ultimate in convenience with the self-emptying base, this robot delivers on its promises. However, for those living in smaller apartments with predominantly hard floors and no pets, a less advanced and more affordable model would likely meet your needs without the premium cost. Ultimately, the Roomba s9+ is a cutting-edge appliance that successfully automates deep cleaning for those who need its specific set of powerful capabilities.
