irobot roomba s9+

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.

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.

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.

Pros and Cons

Pros

Cons

I can confidently say that the that the iRobot Roomba s9+ is a game-changer in the world of robot vacuums. The self-emptying feature is a huge plus, as it saves me time and effort. I also love how it detects and cleans around objects in my home, making sure that every corner is clean.

However, I must admit that the vacuum is quite loud, and the rubber scrapers/rollers can be pretty annoying at times. Despite this, the vacuum still manages to pick up all the hair from my dog, and it does a great job on both hardwood floors and rugs.
