...It's still one of my favorites, I'd say probably top two out of over 70 robots I've tested... Watch in video
💪 Effective debris pickup
...It got that up there really good, even the thick part. That just shows you how big of debris this could actually pick up... Watch in video
📋 No map required for effective cleaning

🤔 ⚡ Small battery capacity requiring recharges during cleaning sessions
...I do expect it to have to come back home and fully recharge, and then come back out and finish the job... Watch quote in video
🤔 🧠 Limited object avoidance capabilities
...This thing's not made at all for, you know, object avoidance, so that's my bad... Watch quote in video
🤔 📉 Higher cost compared to other models with additional features like mopping
...It really comes down to, do you want something that's going to do the best vacuuming possible or do you want one that does great vacuuming and also has a mop that does a pretty darn good job as well... Watch quote in video
🤔 📏 Difficulty cleaning right up against edges and thresholds

👀 Smart mapping capability
...That second clean. And you may notice it's refined the carpet here. And you can choose to turn that on or off, right? If you don't like that, or it's not accurate for you or something, you can change that. But I like having the carpet on... Watch in video
🧹 Excellent edge and corner cleaning
...Because other RoboVacs aren't able to get as far into the corner of each room as this unit is. Or maybe your house is just as dirty, if not dirtier than mine, so you can expect that... Watch in video
🐾 Ideal for pet hair
...So just your typical human hair around the house, your pet hair, things like that, you have nothing to worry about with this vacuum. I'd argue this is going to be one of the best vacuums available on the market to pick up any sort of hair... Watch in video
💪 Powerful suction
...They make the most out of that dual brush design so they can really utilize the suction power that they do have. So I'm really impressed with the cleaning capabilities so far... Watch in video

🤓 Detailed cleaning history and maps
...Here's our cleaning history so far. So we had two full runs and an incomplete run yesterday, and we can get a breakdown. All right. So it's looking and it goes, oh, its path was blocked. So you can learn more about the errors, what was happening... Watch in video
🤔 🎒 Self-emptying base requires bags
...I'd like a version of this base where we have a bagless design, so we don't have to continue to buy vacuum bags to replace it... Watch quote in video
🤔 🔊 Louder than other Roombas on highest suction setting
...It's definitely louder than all the other Roombas at that highest suction setting... Watch quote in video
🤔 🚫 Issues with thick shag rugs
...I don't recommend having any RoboVac on a carpet or rug like this. Eventually they will all get stuck and tangled... Watch quote in video
🤔 🧹 Minor manual cleaning required after self-emptying
...Only a few pieces of hair left. I'd argue a lot of those were just trapped in either the lid or the compartment down here as it goes to close... Watch quote in video
🤔 💡 Not suitable for homes with thick shag rugs
...Just assume any rug like this in your house, you're going to want to set up that no-go zone... Watch quote in video

💪 Strong suction power
...It has about four times stronger suction power than most other Roombas... Watch in video
🏆 Top vacuum performance
...It's still the best vacuuming robot that we have ever tested... Watch in video
🧹 Effective corner cleaning
...The D shape means it gets significantly closer to the corners and walls... Watch in video
🚀 Excellent on carpet
...By far the best we've ever tested on all of our tests, particularly on carpet... Watch in video
🦸 Great for pet owners
...I'm pretty confident that for sheer vacuuming performance the S9 will be best for pet owners... Watch in video
🌟 Durable and premium design
...It looks very premium which is a good thing considering its price point... Watch in video
🧼 Efficient self-emptying feature
...The auto-empty dock can store up to 30 cleans which is awesome because it means you can leave it cleaning for up to one to two months without having to empty it... Watch in video
🧭 Impressive navigation
...It covers the whole area and can clean right up to the wall... Watch in video
📱 User-friendly app
...Most people seem to prefer it because it's quite simple... Watch in video
🛠️ Versatile cleaning modes
...You can change the suction levels from eco through to turbo... Watch in video
🤔 📉 The battery life isn't very long
...The battery life isn't very long so it's best if you have a big home if you can clean while you're not at home as it will need to recharge and resume a few times... Watch quote in video
🤔 🔊 Quite loud during operation
...It's quite loud at 73 decibels and you wouldn't want to watch tv while it's cleaning in the same room... Watch quote in video
🤔 🌙 Needs lights on to clean at night
...The one downside of a V-slam camera is that you do need to leave the lights on to clean so if you want to clean at night you just have to remember to leave lights on in those rooms... Watch quote in video
🤔 🔄 Navigation isn't as precise as newer models
...The navigation isn't quite as satisfying as some of the LiDAR options but it still covers everywhere and it won't make any material difference in the long run... Watch quote in video
🤔 🚧 Increased chance of getting stuck
...The only one minor con about having the brush right on the front there, and that is it is the first thing that will go over any cable or sock or whatever is on the floor, so I think it's slightly more likely to actually get stuck and not be able to get itself off compared with the other Roomba models...

✔️ Replacement parts availability
...There's a lot of replacement parts available for this Roomba. And the refill kit it's something you're going to have to purchase once a while... Watch in video

🤔 🗣️ Push notifications can feel over-dramatic.

🌟 Battery saving feature improves run time
...[...] the fact that they added this, and are doing whatever they can to save even a few minutes worth of battery, is a step in the right direction... Watch in video
🚫 Effective obstacle avoidance without front lasers/camera
...So just off those two things that it avoided, that's quite impressive because this does not claim ever to have obstacle avoidance... Watch in video
🚀 Innovative software updates enhance older models
...For them to have technology like that on this specific robot that's well over two years old, with no type of front lasers or a front camera, I'm very curious to see how well that's going to work... Watch in video
🛠️ Improved cleaning without hardware upgrade
...So the fact that it's doing that just with the sensors that it already had a couple of years ago, once again, to me, that is very, very impressive... Watch in video
🔋 Improved battery management feature
...Notice how the motor is not on. And once again, yeah, it's only going to save you a little bit of battery, but the fact that it'll save you some at all is a big plus in my book... Watch in video
🤖 Future-proofing existing robots with updates
...[...] the fact that if it's something bigger, like a can or a bottle, probably like a pillow or something like that, it's going to avoid it pretty dang well for what it has... Watch in video
👏 Positive overall experience and innovation recognition
...iRobot definitely has the best software and the best app out there, in my opinion, for what they can do... Watch in video
🤔 🪫 Battery life issues especially when on maximum suction
...Everybody knows this S9's battery was way too small, and it just does not last long at all, especially if you put this guy on its maximum suction... Watch quote in video
🤔 🧩 Inability to avoid smaller objects
...I wish it worked on smaller objects, but once again, this was not designed whatsoever for any type of obstacle avoidance... Watch quote in video
🤔 🕰️ The robot is outdated or old
...I will say, even though I love this robot and I still think it's a great robot, boy, is it outdated. Or, I guess, maybe not outdated, but just old... Watch quote in video
🤔 ⚡ Minimal battery saving features available
...Once again, that's only going to save a very small percentage of battery, but I like the fact that they're doing something to help it, because they know the battery is terrible too... Watch quote in video
🤔 🔋 Poor battery performance compared to competitors

🧹 Amazing cleaning performance on hard floors and carpets
...It’s perhaps the best-performing robot vacuum for vacuuming debris on hard floors and carpets... Watch in video
🌀 Highest airflow amongst tested robot vacuums
...Airflow is excellent, with as much as 25 CFM in its highest setting – the highest so far amongst the robot vacuums I’ve tested... Watch in video
🧩 Wider rollers for efficient debris pickup
...The wide extractors plus relocation also necessitated changes to the side brush design, which is now smaller in diameter, has two more arms, and closer to the edge, making the S9 one of the best, if not the best, robot vacuum cleaning edges... Watch in video
🗺️ Effective mapping and zone cleaning
...Imprint smart mapping allows it to draw maps, pinpoint its location, and clean specific zones... Watch in video
🚪 Handles near-edge and crevice cleaning well
...It aced the edge cleaning test, picking up nearly every crumb on this area. Also, it picked up most debris in this quarter inch crevice – a positive side effect of having high airflow... Watch in video
📅 Saves up to 10 map levels
...One positive with the S9 app can save up to 10 map levels, six more than Roborock and eight more than Ecovacs... Watch in video
🍃 Superior deep cleaning capabilities
...Right now, it’s the best deep cleaning robot vacuum out of all the brands I’ve tested with a 93% pick up, thanks to the high airflow, extra-wide extractors, and dirt detect... Watch in video
📦 Convenient clean base station
...The clean base station adds a layer of convenience since it empties the robot’s dustbin for you, ridding you of this task... Watch in video
🧑‍💻 Customizable cleaning settings
...Custom settings are also available, providing consumers an option to control the power setting manually or increase the number of passes to two if needed for a more thorough clean... Watch in video
🧰 Low maintenance extractors
...One telltale sign of having high airflow is the absence of build-up on the brush roll assembly, which was the case with most robot vacuums I’ve tested. In the S9, there wasn’t much, if any since most of it was picked up and inside the dust container... Watch in video
🤔 💸 High cost makes it less accessible for many users
...So the question is, is it worth the high cost?... Watch quote in video
🤔 📱 App lacks some essential features
...It lacks several features, like live maps and invisible wall, that would greatly enhance usability... Watch quote in video
🤔 🔦 Reliance on a light source can be limiting
...One drawback to using a camera is its reliance on a light source... Watch quote in video
🤔 ⏱ Shorter run time at max power setting
...With the S9, it maxes out at 75 minutes with the lowest setting. If you use max power exclusively, that number drops to around 45 minutes... Watch quote in video
🤔 📣 Produces loud noise during operation
...Another downside of using a powerful motor is the noise. The S9 ranged between 67.7 and 74.1 decibels based on the sound meter test, so it gets loud... Watch quote in video
🤔 🔋 Uses a smaller capacity battery
...One reason is iRobot uses a smaller capacity battery versus its competitors, which is a huge factor... Watch quote in video
🤔 🧹 Rollers require some maintenance to manage hair tangles
...One downside of having high airflow is how the extra juice cuts into the run time... Watch quote in video

🏠 Suitable for various floors

🤔 😓 Bad battery life
