While it comes at a premium price, has a shorter run time, and noisy operation, a large dirt bag inside its docking station, decent navigation capabilities, and exceptional cleaning performance make the S9+ worth the investment for those seeking a cleaner home with minimal effort.
The iRobot Roomba S9+ was released in mid-2019 as a high-end robot vacuum with an onboard dirt compartment that holds up to 388ml of debris and a self-emptying base with a larger 2.5-liter dirt bin. The S9+ works with both Alexa and Google Home (voice control), employs vSLAM navigation, and has a D-shape for more efficient corner and edge cleaning. Like best vacuum cleaners, the S9+ has a 75-minute battery life, and its smartphone app allows for advanced scheduling and setting up no-go zones.
Despite its 3-hour charge time and being louder than most top-rated robot vacuums, the S9+ picks up pet hair large and small debris pretty well from hardwoods and carpets. It also has one side brush but cannot handle wet messes. It uses a high-efficiency filter instead of HEPA and dual multi-surface rubber brushes for more efficient cleaning.
Consensus
our Verdict
The Roomba S9+ impresses with its navigation quality, offering efficient cleaning. Its cleaning performance, particularly on hard floors and carpets, is exceptional. The Robovac offers a 75-minute maximum battery life, placing it in the bottom quarter when compared to other alternatives on our list. It also has a convenient self-emptying dust bin, and advanced features also help justify its high cost. The robot vac picks up 98.2% of dirt and debris on hardwoods and 98.5% on carpets.
Noise output is high at 74 dB, but the S9+ filters allergens efficiently. The Roomba app is intuitive, offering voice control and boundary zones. It doesn’t offer a mopping feature. The S9’s 25 CFM or 2200 Pa tested suction power also makes it one of the most powerful iRobot Roomba robovacs on the market.
Reason to Buy
Decent navigation capabilities
After a few scanning runs, the iRobot Roomba S9+ can accurately map a cleaning area, which is accurately depicted on its iRobot companion app, and its mapping software can save and operate off of up to 10 different maps.
Exceptional bare floor cleaning performance
The iRobot S9+ easily picks up up to 98.2% of debris on bare floors, earning it a top 10% ranking compared to other Robovacs in this category.
Great carpet cleaning performance
The S9+ picks up 98.5% of debris from both low and high-pile carpets.
Large bin size
The S9+ has a 2.5-liter bag size inside its self-emptying bin. This allows it to hold a lot of debris without frequent emptying.
Reason to Avoid
Noisy
The iRobot Roomba S9+ has a high noise output of up to 74 dB. This places it in the top 30% of robovacs in its category.
Below-average battery life
The iRobot Roomba S9+ has a below-average 75-minute battery life. This places it in the bottom quarter of our certified, tested robovacs list.

Compared to the standard Roomba S9, the S9+ is distinguished by the Clean Base Disposal System, which includes a motor, a high-efficiency filter, and a dust bag, which are all essential for automatic self-emptying. This is something that the Roomba S9 cannot do. Another difference between the two is that the collection bin for the S9+ has an access hole where the dirt and debris can be easily removed, while the S9 does not.

While the iRobot Roomba S9+ 9550 has a longer runtime compared to the iRobot Roomba S7, on the other hand, the Roomba S7+ has a larger dustbin capacity than that of the Roomba S9+. Additionally, the J7+ is a lot quieter than the S9+. In case you’re interested in what else the J7+ has to offer, go ahead and take some time to read through our iRobot Roomba J7+ 7550 review.

The iRobot Roomba S9+ 9550 offers more suction power than the Roborock S7. The S9+ also has a larger dustbin capacity compared to the S7. The S7 comes with a water tank that the S9+ does not, but the S7’s battery keeps going for much longer than that of the S9+. For a similar model, check out our Roborock Q5+ review. Or, for another alternative, see our Lefant M210 Robot Vacuum Cleaner review.
