The Roomba s9+ is D-shaped and comes with a Clean Base while the Roomba e6 is round

The docking station of the Roomba s9+ includes a Clean Base

Right away, you’ll notice the difference between the shape of the two Roombas. The e6 follows the traditional round-shaped robot vacuum design while the s9+’s D-shape is a departure from that. Its D-shape is similar to that of the Neato Robotics’ Botvacs. This gives the Roomba s9+ an edge over the e6 when it comes to corner cleaning. Its flat front allows for a more thorough cleaning along the corners and edges of your home.

As for their dimensions, the Roomba s9+ is slightly smaller and an inch slimmer than the e6. The Roomba e6‘s height is 3.6 inches while the s9+ is only 3.5-inch tall. This means the s9+ can go under furniture with lower clearance. With a capacity of 550 mL and 500 mL, respectively, the dustbin capacity of the s9+ and the e6 is almost the same.

While both are equipped with iRobot’s patent dual rubber brush rolls, you will notice that their placement and size are different. Since it sports a D-shape, the Roomba s9+ comes with a wider brush roll (by 30 percent) on the front of the robot vacuum. It also has a better wheel design for a smoother transition from one floor type to another. Its edge brush is also different as it is located on one of its corners and not as stiff as the lower end Roombas’.

On the other hand, the e6 follows the traditional Roomba design where the dual brush roll can be found in the middle. Its brush rolls and wheels are also smaller. The e6 comes with a side brush, but it is stiffer and spins faster than the s9+’s corner brush. This results in some scattering when this robot vacuum is cleaning debris on the floor.

Cleaning Performance

Both work great with carpets, but the Roomba s9+ is more powerful than the Roomba e6

The Roomba s9+ has 40x the suction power of the entry-level 600 series while the e6 is only 5x stronger

Undoubtedly, the Roomba s9+ is significantly more powerful than the Roomba e6. Its strong suction power, D-shape, wider brush rolls, and more advanced iRobot technologies all work together for an impressive deep cleaning even on carpets. As mentioned earlier, it performs well when it comes to cleaning edges and corners of your house, thanks to its updated frame design. The s9+ can also suck finer particles such as sand from carpets and crevices, something many robot vacuums can’t do.

That is not to say that the Roomba e6 is altogether bad. For its price, it does a great job cleaning carpets and hardwood floors and pulling pet hair. As the Roomba e6 is also equipped with iRobot’s cutting edge cleaning technologies (such as the Dirt Detect that can tell when an area is dirtier than usual), it remains one of the best robot vacuums in its class.

It is worth noting that while the Roomba s9+ effortlessly pulls in the sand from carpets, it struggles somehow when faced with larger debris like cereals. In the end, it can still thoroughly clean bigger particles, but it makes a loud noise when doing so.

Mapping and Navigation

The Roomba s9+ has a more advanced mapping and navigation capabilities than the Roomba e6

You can block off areas with the Roomba s9+ using the app, but the Roomba e6 relies on Virtual Wall Barriers when setting boundaries

Both Roombas can work around obstacles when vacuuming, but since the Roomba s9+ is equipped with a camera, it does the job significantly better. The Roomba s9+ comes with iRobot’s iAdapt 3.0 while the Roomba e6 only comes with the iAdapt 1.0. With the camera-based vSLAM (Visual Simultaneous Localization and Mapping) of the s9+, it can map straight cleaning paths efficiently, unlike the e6 that goes around the room randomly.

As the Roomba s9+ is also more advanced, you can label the different rooms in your house and save maps for different floor levels. The app also lets you set up boundaries through its Keep Out Zone feature. Meanwhile, the Roomba e6 can only set boundaries through its Virtual Wall Barriers that you can place along the areas you want your Roomba to avoid. If you have a bigger floor size and have more spaes you want to block off, two Virtual Wall Barriers may not be enough.

Run, Recharge and Resume

The Roomba s9+ can resume cleaning where it left off

Even after charging, the s9+ remembers which paths it has cleaned

If you have a larger floor size, your Roomba might not be able to cover everything on one go. Both the Roomba s9+ and e6 can automatically go back to their base, but only the s9+ can resume cleaning where it left off, thanks to its more advanced mapping and navigation system. The Roomba e6 will just randomly clean areas after it’s fully charged and you might even need to empty the dustbin first before it can resume cleaning.

The Romba s9+ can run for up to 120 minutes on one go, while the Roomba e6 has a runtime of up to 90 minutes, a bit shorter if they’re working on carpet boost. To run on a full cycle again, both the Roomba s9+ and the e6 need to be charged for up to 180 minutes.

Control Options

Both can be used with the iRobot HOME app and are compatible with smart assistants

You can schedule cleaning using the app even when you’re not home

You can check cleaning history, schedule cleaning, and monitor your Roomba’s progress using the iRobot HOME app. As the Roomba s9+ is more advanced, you can do more through its app, such as labeling rooms and areas in your house and setting Keep Out Zones to block off certain areas.

Both Roombas are compatible with voice assistants like Amazon Alexa and Google Assistant so you can enjoy hands-free cleaning even when your hands are full. Since you can label rooms in your house with the s9+, you can command your smart assistant to clean specific rooms without covering the ones that don’t need vacuuming.

Additional Features

The Roomba s9+ comes with a Clean Base for automatic self-emptying while the e6 comes with two Virtual Wall Barriers for setting boundaries

The Automatic Dirt Disposal technology in the Roomba s9+ makes cleaning more convenient than ever. Whenever its dustbin is full, the s9+ will trek back to its Clean Base and its motor will start sucking in the dirt. This Clean Base can hold up to 30 dustbins, thus you won’t have to keep emptying the dustbin everytime you run the Roomba s9+. Even if you’re not home to empty the dustbin, you can still ask your Roomba to clean your house and not worry about the dustbin getting full in the process.

This feature is not available in the Roomba e6. What comes with the e6 are two Virtual Wall Barriers and an extra High-Efficiency Filter. As earlier stated, the Virtual Wall Barriers allow you to block off certain areas you don’t want your Roomba to clean.

Both the Roomba s9+ and Roomba e6 use High-Efficiency filters that can trap allergens such as mold particles, dust mites, pollen, pet dander, and other allergy-causing particles. Even the bag inside the Clean Base of the Roomba s9+ boasts AllergenLock Bags to ensure irritants are trapped even after they they are transferred from the dustbin.


Bigger houses will benefit from the Roomba s9+’s more advanced features, but for smaller to medium floor sizes, the Roomba e6 is a great choice for its price

If we won’t consider the steep price, the iRobot Roomba s9+ is undoubtedly the better, smarter, and more powerful robot vacuum. Its advanced technologies, especially the Clean Base and Automatic Dirt Disposal, have made cleaning more convenient than ever, particularly for homes with a larger floor size.

However, the Roomba e6 gives overall better value for your money. For almost a quarter of the price of the s9+, you will get a powerful vacuum for its class that does a great job cleaning carpets, hardwood floors, and most floor types. It also comes with iRobot’s tried and tested cleaning technologies such as the Three-Stage Cleaning, Dirt Detect, and its patent dual rubber brush rolls, among others.
