iRobot Roomba s9+ Review: The Ultimate Self-Emptying Vacuum
By Alexander Arnaudov Last Updated April 12, 2024
At first glance, the Roomba S9 Plus may seem familiar, but its innovations set it apart from its predecessors. Most notably, it comes equipped with a self-emptying feature, revolutionizing the way we handle vacuum maintenance. Instead of manually emptying the dust bin every few days, the Roomba S9 Plus effortlessly transfers debris from the vacuum into a bag located in its charging station. With a bag capacity of 14.9 ounces (440 milliliters), roughly equivalent to 30 cleaning sessions, this feature transforms a daily chore into a monthly task—a godsend for those pressed for time or simply averse to manual maintenance.
In addition to its self-emptying prowess, the Roomba S9 Plus incorporates a high-efficiency filter tailored to allergy sufferers. Boasting an impressive capture rate of 99 percent for mold, pollen, and dust mite allergens, this filter ensures that your home remains not only clean but also conducive to better respiratory health.
But the Roomba S9 Plus doesn’t stop there. Its intelligent navigation system, powered by vSLAM technology, enables it to effortlessly maneuver around furniture and obstacles, ensuring thorough coverage of your home’s floors. Coupled with its Power Boost technology, which automatically adjusts suction power when transitioning between different floor surfaces, the Roomba S9 Plus delivers unparalleled cleaning performance across the board.
Design and specs
The iRobot Roomba s9+ stands out from other robot vacuums due to its innovative design and powerful performance. One of the most noticeable features is its unique D shape, which enables it to reach deep into corners for thorough cleaning. Despite its compact 12.5-inch diameter, the s9+ boasts a height of 3.5 inches, providing ample space for advanced cleaning technology.
Impressively, the s9+ is equipped with two of the longest main brushes in the industry, measuring 9.5 inches each. Positioned closer to the front of the unit, these brushes are designed to enhance corner cleaning and ensure efficient debris pickup in a single pass, setting it apart from other robot vacuum models.
With its 100% Power-Lifting Suction technology and PerfectEdge technology, the Roomba s9+ can thoroughly clean even the tightest corners and edges of your home. Plus, the vacuum’s advanced sensors and specially designed corner brush make it ideal for homes with pets, as it won’t get tangled with pet hair.
Power-Lifting Suction and Cleaning System
I was blown away by the power and efficiency of the iRobot Roomba s9+ Self-Emptying Robot Vacuum’s Power-Lifting Suction and Cleaning System. With 100% more power-lifting suction than the Roomba i Series robots, this vacuum is a powerhouse cleaning system that can clean thoroughly, even into corners and along edges.
The vacuum’s advanced technologies enable it to detect and clean around objects in your home, making it easy to clean even the most hard-to-reach areas. I was impressed with how it thoroughly cleaned corners and edges, leaving no dirt or debris behind.
The s9+ empties itself into the Clean Base Automatic Dirt Disposal that holds months of debris, making it a hassle-free experience. Its learning never stops, as it offers up personalized cleaning recommendations that work around my life, pollen seasons, and peak pet-shedding times—so that it’s always one step ahead of the mess.
PerfectEdge Technology and Advanced Navigation
The specially designed Corner Brush and advanced sensors, along with the approximately 30% wider Dual Rubber Brushes make it ideal for homes with pets. It offers optimized cleaning deep into corners and along edges, leaving no spot untouched. With vSLAM navigation, the s9+ learns the layout of your home and builds personal Smart Maps, enabling it to expertly clean and navigate in neat, efficient rows.
The Keep Out Zones feature is also a great addition, as it allows me to set boundaries that my Roomba should avoid, like pet bowls or play areas. The robot vacuum is smarter than ever, learning where and when I normally clean and suggesting personalized schedules so I can focus on everything else. The Roomba s9+ also works with Imprint Link Technology, allowing it to team up with the Braava Jet M6 robot mop (available separately) to vacuum and then mop automatically in perfect sequence, giving my floors a comprehensive clean with just a command to my voice assistant or in the app. Overall, the PerfectEdge technology and advanced navigation are some of the best features of the iRobot Roomba s9+ self-emptying robot vacuum.

The s9+ also has Smart Mapping technology that allows it to learn the layout of your home and build personalized maps.

The vacuum also has a self-maintenance feature that keeps it functioning at its best. It has a filter that captures 99% of allergens and dust, which is great for those with allergies. The filter is washable and reusable, which means that I didn’t have to worry about buying replacement filters.
