Customer Ratings & Reviews

Bought this because I had a Roomba 980 previously that impressed me and I wanted to try out the new mapping features. What a mistake, just problem after problem, absolutely no quality control from Roomba anymore. I replaced mine over 4 times not only did they all have trouble mapping with any bit of success they each had different issues aswell. Ghost mapping, mapping through walls, repeatedly hitting the same spot on the wall over and over (and hard sometimes), spinning in circles endlessly, parts breaking/wearing way too quickly, rubber wheels being worn down in a few weeks due to getting stuck or trying to repeatedly push an object, the rubber brushes/rollers get tangled in long hairs and wear down MUCH quicker than my old Roomba's do in the same area. I could go on but I've wasted enough of my time, trusting surely this 4th replacement will work. It seems like iRobot/Roomba's quality control is abysmal, how can you launch an over $1k product like this. I would avoid all iRobot products at all costs. Unless it's maybe a used 980, that thing is a beast on carpet, no fancy mapping features but it just works, unlike iRobot's newer offerings...

The robot did most of the job I want it to do. It creates an OK smart map. The noise is not quite high, it is quieter than my Dyson V6. I like it, but it sometimes still got stuck on my rugs and it scratches itself very much. I am not sure if it supposes to keep scratch itself with hitting the wall with its backside. I bought another s9 clean base to make it be able to charge on both my 1st and 2nd floors. The clean base and the D shape are nice. It needs light to do the job which is kind of annoying when you are not home. Overall, I like it but I hope it can improve better with a software update or something. If we can have a live time location of the robot on the smart map, that would be nice.

PROs: - The new D-shape visibly allows for deeper penetration & better cleaning into corners than the previous circular shape--it also sports bigger/longer roller brushes to clean more with each pass - Room mapping & object avoidance was stellar...hugged walls/furniture edges much closer than I expected & managed to wiggle between table/chair legs, underneath couches, between bed posts, around speakers & decor...and the corner brush pulled gunk away from baseboards & actually left the rooms about as clean as I would get with a manual vacuum - Sensitive/responsive front bumpers help prevent damage to items close to the floor...automatically backs up, routes around obstructions, and remembers or avoids obstacles on future passes—very cool! - Shocking amount of suction for such a small device--initial cleaning pass covered 750+ sq feet and pulled up so much dirt I wasn't sure how it still managed to cram it all into the dirt bin - Roomba app gets five stars and a parade for usefulness, user-friendliness & intuitive design/interface--a multitude of helpful status indicators & messages, step-by-step pictorial guides for maintenance/troubleshooting, scheduling wizard for cleaning times and even specific locations if you'd like, customizable maps, power level adjustments, locator functions, tutorials and FAQs...it's quite extensive but not overwhelming in presentation - Charging or attention required (close lid, empty bin, etc.) doesn't cancel cleaning job...returns to its base on its own for any necessary re-charge or to await user intervention and then resumes the last job already underway (unless cancelled manually in the app or at the unit) - Outstanding smart home integration--we added Roomba to Alexa's skills and could then use voice control to clean specific rooms, start a whole-floor cleaning job, schedule new cleaning routine, return to home base when company arrived, play a locator tone, etc.—having so much control without needing the app elevated the “hands-off” experience to a whole new level - Automatically detected transitions between hardwood flooring, carpeting, gel standing pads, & area rugs—you could hear it adjust suction and brush action; never once fell down the stairs or failed to keep moving past shallow flooring features/bumps - Despite (advertised) massive increase in suction power (supposedly 4-40x over previous models), the s9 never faltered on our runners & rugs, even going so far as to back out of situations where a tassel started getting hung up in the rollers—hats-off to the AI programmer - Battery life was very impressive--a single charge lasted more than 5 hours of continuous use that included 3 hours of mapping (no suction/cleaning) and 2+ hours of “quiet clean” vacuuming covering just under 2000 square feet (the app helpfully tells you how much area was covered)...and there was still at least 1/4 charge left when it returned home and it was back up to 100% in less than 2 hours - Dust-bin removal/emptying is an easy, one-handed job: open the top of the unit, lift out the bin by the integrated handle, press the release button once you’re over a garbage bag—this will remove nearly all nastiness that accumulated during the last cleaning run (a more complete bin cleaning that includes the filter will require a little extra effort--see below) - On-board spot-clean button allows for a spiral vacuum routine in any room or non-mapped area without needing to schedule a select/all-rooms cleaning - Maps that are stored on board get more detailed & precise each time the unit does its business but cleaning can handle minor changes in the landscape—even when we trained the Roomba in a location with a large box on the floor, it still vacuumed up the carpet below once we removed the box later CONs: - I didn't get the automatic dirt disposal station, but I can see where once you’ve invested in the s9, you might as well pony up for it—the s9’s dust bin is pretty small and if you have an area requiring lots of attention due to pets, kids, high traffic, etc., you might get tired of all those trips to the garbage can - Speaking of the automated disposal station, that thing better have a jet engine for a motor in it. The design of the dust bin is such that the bottom of the air filter is open-faced against the area where dirt is collected--the tight folds of the filter material holds the dirt in even tighter clumps so you need to remove the filter from the housing and shake/bang the dust off to restore air flow/suction. Those of you with visions of never having to sweep out a vacuum’s dust bin by hand will still find yourselves scraping away dirt clumps & hairballs to get the bin clean again - You can adjust the suction power for “Quiet Clean,” but even then the unit is still a bit loud in operation—unless it’s operating a floor away or behind closed doors, it was loud enough to be intrusive; we couldn’t have it running during dinner, while were in the next room watching a movie, etc. - Okay, this part I didn’t see coming—the air filter needs replacing every few months as does the rotating corner brush; the multi-surface brushes and rear caster wheel also need annual refresh. iRobot sells a kit with 3 filters, 3 corner brushes & 1 main brush set for $75; the rear caster will set you back another $6 (plus shipping). I don’t necessarily begrudge needing to replace these parts given that the payoff is virtually hands-free floor cleaning—I just didn’t know going in that the cost of ownership would be an ongoing burden - The soft-touch plastic finish gets marred pretty easily, especially when the unit is cleaning near/underneath kitchen cabinetry or low-slung furniture like couches or upholstered chairs…after the first use, there was a huge scuff running all the way across the “Clean” button; by the end of the first week it looked like I had dragged the Roomba behind my car. Mind you, it’s just my vanity talking here—but it’s still a mildly disappointing cosmetic development for an otherwise really good-looking robot vacuum clocking in at nearly a grand…and because it needs quite a bit of clearance on all sides for its base station, you kind of need to keep it in the open where others might see it (if stuff like that even matters to you) Summary review: Okay, for our first robot vacuum, the s9 was admittedly an indulgence that went a bit over the top…but man alive, does it do its job well! The new design seems much better suited to corner cleaning and hugging walls than the older circular design, and putting the larger rollers way up front near the rotating corner brush means baseboards & edges came away surprisingly clean. Like any vacuum, stray cords bound the unit up just slightly, but I was impressed to see it back out of the dilemma without any manual intervention. In fact, other than emptying the dust bin (okay, we actually have to do that a lot) and initially putting the Roomba on its charging station, I haven’t touched the unit with my hands since I opened the box. The companion app also has enough features, customization settings, and helpful indicators that you actually feel like it’s a useful and even necessary part of the experience, rather than just an appi-fied wrapper for the manufacturer’s website. Better still, Alexa integration went smoothly and affords you voice control that ranges from utilitarian (“Alexa, ask Roomba to vacuum the master bedroom”) to whimsical (“Alexa, ask Roomba to play dead”—which paused the current cleaning job). As to the unit itself, its methodical navigation routines mean that in open areas, you still get those cool, lawnmower-style vacuum carpet marks where the deep cleaning took place--but the s9 is equally at home on hardwood & tile flooring and the results are every bit what you’d expect from a top-of-the-line robo-vac. My wife actually admitted yesterday that she is starting to understand the allure of what is otherwise a pretty spendy indulgence because she’s noticed she no longer feels those little crunchies and dirt particles underfoot. Given that she normally doesn’t wear shoes in the house, this alone is a glowing endorsement to how well the Roomba keeps our floors clean and tidy. While there will always be those occasions where you simply need a manual cleaning, for regular upkeep, this unit really goes to 11 across a broad range of hard and carpeted floor coverings. My only “complaint” really centers on the price of admission. In exchange for virtually effortless & hands-off vacuuming, I do have to engage in some occasional hands-on maintenance & semi-regular purchases of consumable parts. Knowing that now, I might suggest a slightly cheaper model that provides similar results given that you’re probably going to be buying replacement parts across the entire Roomba line anyway. But there’s no denying that this unit has a more effective cleaning design than its circular brethren—add in the increased suction power, better navigation camera and 3D sensor, better edge-hugging mapping & cleaning routines, and other in-app capabilities that are reserved for the premium-priced models, and you start to understand why and how the s9 commands its premium price. Is all that worth it? Given that my spouse stays at home, the time returned to her by not having to clean the floors, and the comfort the Roomba’s results affords her in our home, definitely make it a worthwhile proposition for me. If you’ve already got your sights set on a unit in this price/performance tier, the s9 should definitely be on your short list!

The s9 does a great job. As long as you don't move things like furniture. For example coffee table or dinning room table. If you do it has to remeasure from walls and chairs and what not. So you need to keep everything in the same spot and it will do an awesome job..

I bought this $1,000 robot vacuum cleaner hoping that I could set a schedule and have it clean my home while I was away, or doing other things. I was naive and foolish. This unit gets stuck, on average five or six times on my kitchen table and chairs, even though I tilt the chairs to prevent the vacuum from getting stuck on the chair legs, which it does 100% of the time if I don't tilt them up. It does well in the rest of the house so long as I prepare the house for it by putting drapes out of its reach, pulling the bed covers up on top of the bed, ensuring no USB or power cables are on the floor, and move the coffee table to the sectional so the robot won't get jammed under it. What would help a lot is if you could tell the robot: don't go to this little area. You can tell it not to do entire rooms, and I suppose I could fiddle with it to set up a "room" that only includes the spot where the kitchen table is, so maybe I will try that. Overall, my advice would be to check out your home to see where a robot cleaner would get stuck before getting one of these.

The Roomba S9 is a premium robot vacuum that comes at a very high price. The vacuum works extremely well, but is still not perfect (which feels rather surprising due to its high cost). It is rather loud and makes a degree of varying noises as it moves over different surfaces. It typically transitions well as it moves from hard floors over area rugs and across carpet, but because the noises change with each surface - it often sounds as though it is stuck - when it is actually working just fine. You can reduce the suction for a quieter clean, but it is still rather noisey. I recommend setting the schedule to clean when you are not at home. If there are any errors, the Roomba will pause, return to base, and you will get a notification through the app. We have two dogs and a 4 year old - which means that we have a lot of clutter for the Roomba to navigate around. The vacuum does an exceptional job at finding and tracing the edge of walls - And, it had no trouble mapping out our main floor. It took about 3 trips through the house to have it fully mapped. Once the iRobot knew its way around, we were able to draw boundaries and name each room within the app. Now, we are able to tell Alexa to vacuum a specific room and the Roomba does the job and returns to the base when it is done. The roomba is actually so smart that it can pause the job if the dust bin becomes full, or if it needs to recharge. Once these issues have been addressed, the vacuum can actually continue working right from where it left off. In my opinion, iRobot has done a poor job of marketing. Even the information on the box left me wondering what was new about the S9 (and why it cost so much more money). The main difference appears to be that it has 40X the suction as the previous 600 series. 40 times the suction sounds too good to be true, but I can confirm that it does an excellent job vacuuming carpeted areas. When I carry the Roomba to our carpeted upstairs, it instantly knew that it was in a new area (not the mapped out downstairs) and it started to make a new map. I very much like that the robot leaves nice parallel vacuum lines in the carpet (instead of a bunch of crazy zig zag lines from driving around all willy-nilly). See the attached pictures which show how nice the vacuum lines look after it’s very first attempt at vacuuming our carpet. What I particularly appreciate is that the S9 is designed for homes with pets and those with allergies. The vacuum does a truly wonderful job at sucking pet hair off of our wood floors and also out of our various area rugs and carpet. While it cleans, it also filters 99% of mold, pollen, and other dust that triggers allergies. While the vacuum does a great job at navigating the house, it does occasionally get stuck. It absolutely cannot handle shag carpet. If you have carpet, or an area rug with long fibers - be aware that even this high end robot cannot vacuum such areas. Surprisingly though, we have not had any trouble with toys, shoe laces, dog bowls, area rugs, bathroom rugs, stools chairs, tables, etc. If you can afford the Roomba S9, I would actually recommend saving up the additional cost to get the S9+ as that model is able to empty its own dust bin 30 times! It even keeps all of the dust contained when it transfers into the larger bin that is built into the home base. The S9+ will truly be trouble free cleaning. With the S9, you are required to empty the bin almost every time the vacuum runs. Luckly, the default setting will keep the robot working even when the dust bin is full...Though I recommend changing that setting so that the Roomba will return to its home base when the dust bin needs to be changed. Be aware that filters, rollers, and the corner sweeping brush all need to be replaced. Generic filters can be found, but here are the parts that you will need to locate: Replacement Parts: - Roomba S Series Replenishment Pack (contains replacement rollers, filters, & corner sweeping brushes) (Best Buy info: Model:4646124. SKU:6352888) - Roomba S Series Filter 3 Pack (iRobot Item # 4643682) - Roomba S Series Corner Sweeping Brush - 3 Pack (iRobot Item # 4646123)

I’ve always lived in a house with a dog — sometimes multiple dogs. So, I’ve always been a little OCD when it comes to keeping the floors vacuumed and free of pet hair. The only problem is that with my schedule, it makes it hard to take the time to vacuum as much as I would like to keep things tidy. My daughter has been trying to help out and vacuums a couple of times a week, but she has her own life, too, so I thought that maybe a robot vacuum would be the way to go. A couple of years ago, I tried a third-party branded robot vacuum that simply did not work the way I hoped. It constantly got lost and stuck in places that it shouldn’t have gotten stuck. So, when I was introduced to the S9 from iRobot, I wasn’t expecting much. I ended up being in total shock with how well this little robot vacuum did. It’s super cool! The first time you use the vacuum, it makes a map of your home. This is a really cool feature, but I do wish that I had more options like being able to adjust the map more so that the vacuum would avoid certain spots where it’s prone to get stuck like underneath my couch. What would be great to see is a feature where you can map your home by controlling the vacuum like an RC car. You could drive it around remotely with the iOS app and the vacuum could create the map based on your navigation. As it is right now, my home map doesn’t look like my home. The S9 does a wonderful job, but the map it created has some weird turns. As far as cleaning goes, the vacuum does a really good job and the deep clean function really is a deep clean. Unfortunately, the battery runs out quickly when you use the deep clean feature. I have done a few deep cleaning cycles and then used the custom option inside the app to change it to less of a deep clean so it can do the entire house in one charging cycle. I will switch back and forth depending on how badly it needs it. The vacuum does a great job at collecting dirt in corners and along base boards. Way better then I would have imagined it doing. Removing the bin to empty the trash is super simple. The sensor does get dusty and needs to be cleaned every so often but overall, I am not disappointed with the results from my personal R2D2 unit. The changing base is a bit aggravating because I have had it move on me when my Roomba is trying to dock. We ended up using carpet tape to keep the base in place so that when the Roomba docks it never moves making sure that I have good charge at all times. iRobot really knocked it out of the park with the S9. I have a 1485 square foot home and it does its job phenomenally well. An added perk is that having this robot vacuum means that my daughter is off the hook with vacuuming twice a week and that makes her extremely happy. What’s funny is that the robot vacuum actually does a better job than she does cleaning.

Beyond my expectations, lives up to the hype. It’s simply incredible. Does a fantastic job. I have a yellow lab that sheds like crazy. Hair is everywhere all the time no matter how much cleaning you do. The iRobot 9s changes everything. It does everything it says it will do. Super easy to set up, super easy to program and always returns to its base when done.

This is really a smart cleaner. The best use for it is for the routine daily clean after a primary thorough clean. It will keep it super clean. Actually, it is able to better clean than my regular heavy duty carpet vacuum cleaner. I have a cat with the common cat's problem: Shedding hair! This Robot Vacuum keeps all the carpets super clean as if no hair was shed. It is also capable to clean the wood floor I have. I have the first floor of my house with mix wood and carpet and some places with carpet over another carpet. There are a lot of other furniture like chairs and so on. It is like a field with obstacles. In the manual, it says to monitor the Robot at the first time work. To mention here, it is really important to first of all get the robot connected to your WiFi and then update it to the latest firmware. I noticed some improvement after doing so... So to the cleaning, it started cleaning the area around it charging base. It can easily over come carpet over carpet slopes by lifting itself up. It is kind of noisy while working but still acceptable. I mostly schedule cleaning when I am not at home. Be careful as it will trigger your alarm motion sensor... Vacuum suction power is very good, catching every thing on the carpets and the wood floor. The small rotating brush on the side is also very good removing dirt from tight corners. It easily detects the surface type and adapt its cleaning methods accordingly. I activated the beta feature of WiFi signal mapping. It is kind of accurate I can tell. After several times cleaning, the robot was able to identify the first floor as zones that I can limit the cleaning task to some of them. Some areas are not frequently used by my cat... That can be handy... It does great job turning around obstacles and not just banging it head over and over for the same obstacle. After finishing or when the battery is low, it will head back to its charging station. Parking is impressive with all the steps taken. I'd say, the best usage for it is really in a small office or apartment with mostly carpet floor. You will never have to clean again. The dirt compartment is kind of small. I never let it overfill... I mostly harvest cat hair and some dirt after cleaning. It might be not necessary to empty it every day but it is a good practice to do so. In the phone app, you can also change the cleaning noise level if you get very annoyed by it. I set it to the max and it is not that bad. At all... I know it will also work with Alexa and Google Home... I am not using them that much but I can see some people might benefit from this feature.

Roomba S9 can't finish to clean a clear room without stuck. It has big navigation problems. iRobot supports does not answer my questions.

When I took the Roomba out of the box, my initial reaction was: "wow, this looks extremely well built, sturdy and powerful." It took a few minutes to remove it from the package, download the app, connect and start. The robot comes with a partial charge, so it's recommended to have it charge a few hours before the first use. I found a great location to keep the robot downstairs. There are two types of surfaces the Roomba will clean: linoleum and tile. I don't recall exactly the square footage of downstairs, but I want to say it's about 900 sq feet. I'm sharing that because how long the machine runs is directly related to the size area it's cleaning. Pros: Works better than thought Battery Mobile app WIFI Built in Batter charge station Start and end from smart device Can create a schedule Powerful Transitioned well between different surfaces Vacuums for you! Easy to empty Smart map capable so you can have it clean certain areas of the home Cons: Pulled the thin kitchen mat Loud Time consuming pending on the size of the home, but not a deal breaker First run through: I was really impressed. It took just over one hour to clean almost 900 sq feet. I think it took this long because of the amount of objects it worked around. Second time: Took 45 minutes to clean. Maybe it was because I moved a few items around to make it easier to access. The robot has a bumper on the sides and is really good at adjusting itself to maneuver... I think removing some of the chairs was a time saver. Third time: Smart mapping was ready and I was able to designate which area of the house to clean. I tested it out and it was impressive. I feel the more it's used the more efficient this feature will be. Final thoughts: I highly recommend this product. It's larger and more powerful than its predecessors. I love the fact that I can schedule this to run while I'm at work. Even though it doesn't take long to vacuum my home, it pleases me that it's one less thing to do when it's time to do chores. I have two dings: loudness and can pull mats. Both aren't deal breakers and I was able to make minor adjustments. I simply run it while I'm out so the noise doesn't bother me and I drape the kitchen mat over a chair. I love the idea if I make a mess in the kitchen, I can pull out my iPhone and tell it to clean the kitchen. I really recommend this!

Roomba took a cue from the Neato Botvac and ditched the hockey puck shape. I've been researching robot vacuums for over a year and really wanted a Roomba 980 but at around $800 I couldn't pull the trigger on it as it was consistantly beaten in head-to-head comparisons in corner and edge cleaning by the Neato's square, forward-facing shape. The D shape of the S9 alleviated my fears and the performance and navigation is impressive. We have 80% hardwood flooring with carpet in the 4 bedrooms but our hardwood is probably 30% or more covered by area rugs. We have 3 kids under 10 and 2 big dogs so there are random socks, toys, etc. scattered everywhere and dog hair and dust are a constant. After picking up the clutter on the floor I ran a training run on the Roomba. No suction, just a mapping run. The S9 came off the charging dock, did a circle and went back to the dock. The error message on the history log simply said "Stuck". Time and again the S9 would leave the dock, turn around and come back. Reestablishing the WiFi connection didn't work, powering the unit down and back up didn't work, uninstalling and reinstalling the app didn't work and removing my specific unit from the app and adding it again didn't work. After messing with it for several days I finally gave up. I sat down to write a horrible review but then decided to contact the iRobot tech line. The agent connected with my S9 and after trying a few different options she did a factory reset and the Roomba took right off. She must have been able to preserve the settings I had entered because no further input from my end was required. The first time it actually got out of the gate it cleaned for 1 hour and 33 minutes before returning to the base to charge. I watched the s9 the entire time and can say that it doesn't miss much. I paused the job 5 times to empty the dust bin and it was embarrassing. There was so much dust and hair in the bin I almost felt sorry for the vacuum. The s9 isn't what I would consider loud. You can hear it but unless you're a light sleeper I don't think it would wake you up. There is an audible increase in power when transitioning from hardwood to carpet but the volume level is still far from obnoxious. One of our rugs has tassles that are approximately 3" long and I was certain they would tangle in the brushroll and cause the Roomba to stop but it went right over them again and again with no issues at all. We have been using the s9 for over 2 weeks now and we have only had to manually return it to base 2 times. The first was because we placed the Roomba in the back of the house to start a job. The battery ran out and the machine just quit in the middle of the floor. I was disappointed but learned that if the unit does not start a job from the base, it will not return to charge. No big deal. The second time was when one wheel of the Roomba went over the lip on the bottom edge of a dollhouse and it couldn't back out. We helped it over the lip and it took right off and resumed it's job. Corner and edge cleaning is exceptional but leaves me wondering why there aren't brushes on both corners of the s9. I would think that would eliminate a lot of turning around and returning to finish the edges. There are 3 cons to the s9, 1 of which is easily remedied. First, despite being chock full of technology, the s9 still uses a bump-and-go way of feeling around and I have noticed some white paint from our kitchen island on the machine and a dark spot on the island. Slightly annoying but not enough to deter me from using the Roomba. Second, about 20% of the time while attempting to access the s9's settings, job logs, etc. I receive a message that in order to use these features, my phopne has to be on the same network as the Roomba. They are on the same network. Have been since day 1 but still the message continues to come up. Normally a power down of the Roomba fixes the issue. The third con is emptying the bin. It holds a lot but is still a tiny receptacle. Fortunately, an agent at iRobot confirmed that the s9 is compatible with the self-emptying base of the s9+. I will be adding one shortly. Yes, it's $300 so do yourself a favor and get the s9+ with the base in the first place. You'll save a little money, have the best robot vacuum on the market and since the self-emptying base is supposed to hold up to 30 bins of debris, you'll hardly have to think about it.

It’s a little loud and it did pull out strands my wool rug. It works nice on my regular carpet and hard wood and does follow a pattern making sure it does go over every space possible. It hasn’t gotten stuck yet. I do have a husky so it is a necessity to run daily sometimes multiple times. The canister does hold a Decent amount and the battery lasts. My home is 2800sq and I mainly use it downstairs. I can finish the downstairs on one charge and usually only have to empty it at the end. I have it programmed to Stop when it is full Incase more than one is needed.

This is my second Roomba. I bought the basic one first, which was like watching a pinball game. This thing had no purpose and just bounced from wall to wall. This bot, the s9, will suck the padding off your throw rugs but can't find it's way back home! We've repeatedly found it just banging its head on the same hallway wall. It works great if I tell it one specific room at a time, although it still gets lost going back to the dock. (I keep the dock in the tiled foyer with easy access and entrance to the home.) If I set it to do the whole house on a timer, which would be wonderful, . . it's a train wreck. Not once since I've had it, (going on 1 month), that it hasn't either gotten stuck or lost. I have a 2100 square foot house, but all single level, and even though I ran the "practice runs" multiple times, it can't find it's way from one end to the other without giving up in the hallway. It also has issues navigating around furniture. Plant stands, utility shelf's and bar stools are the worst. They become cages and it gets locked in or under. Also, the WiFi connection does not work if I try to program or start it via mobile device unless I'm standing right in front of it while it's docked. If you have no rugs or furniture with peg legs and a smaller square footage, I'm sure this would work great. As I said, the suction is great. However I'm considering returning it and trying a different brand.

Pros: Good suction, the roller design is really good to catch hair without getting stuck in roller, software is almost perfect Cons: The dustbin is small and need to clean up every charge of battery, noisy, charge of the battery is not good enough, sometimes the roomba stops because it runs out of battery and did not go back to base. Overall this new S9 is better than other versions.

I have the Roomba 980 and exchanged it for the s9. This vaccum cleans very well especially because of its new shape. However it’s very loud, especially when it’s on quiet mode. I love the options of selection certain rooms to clean and that the batter life is longer. It doesn’t need to charge to clean the whole house.

At first I was wondering what is going on in his artificial brain lol,that was only because it was mapping my house so precisely it took a week. During that week I figured out you can play with the power on the app,I got it all the way up for a week or so and my house has never been cleaner,I should mention I have two dogs and both shed so much that I had to sweep every day twice for years with great roomba vacuums.but this one is a game changer,it goes everywhere cleans deep carpets like no other,changes his power level to half when on hardwood floors or tile.never leaves untouched spots,empties himself and goes right back to work.charges himself and goes back to the same spot he left off.feels like a real cleaning service:),my bravaa jet nips after the vacuum is done and stays so clean cause the vacuum got everything!!! It’s been a couple months now and this thing is my best friend.thank you Best Buy lol

In terms of technology this is probably the most advanced robot vacuum with the best suction. Unfortunately, it is also the loudest robot vacuum I have ever used! When I received the vacuum, I unboxed it and set up the charge base and then I placed the vacuum on the base. This step was a little tricky because the charging contacts do not line up when the vacuum is closest to the base tower so you have to pull it back a bit until the vacuum lights up and chimes the charging tone. The next step was to set it up with the iRobot app. This was fairly easy and the app found the robot pretty quickly I then hit the clean button in the app and the vacuum undocked and started to vacuum. That’s when we heard the noise it makes, it sounds kind of like a lawn mover for your floors! I then sent the pause and home commands to the vacuum, it headed back to the base but the noise did not get any quieter on the trip back. Once it got back to the base the vacuum motor then revved itself up to its fastest speed, apparently to empty itself but I don’t even have the tower bin. I contacted iRobot tech support to see if there was something wrong with my unit. They asked me to remove the brush bars, check them for any damage and replace them. I put everything back together and tried it again, same noise. I then check the settings in the app and I noticed that there was a quiet mode, so I turned it on and sound died down to an idling lawn mower. I asked them about if the noise during quiet mode and the return to base ramp up noise. The support rep said that they were both “normal”. He then asked if I liked the vacuum’s performed and I told him I don’t know how it performs because it’s so loud that we shut it off before it can do anything. I ended up returning the S9 unit and I purchased the i7 model. Unless you are planning to have the S9 vacuum when you’re not at home, my advise is do not buy this unit It’s just too loud to use while at home.

A real disappointment for the price I paid! The small circular rotating brushes twisted and jammed the robot after several hours of use, the first time I used it. Since I work every day, this Became a problem! I only have hardwood floors, so I don’t understand why this is happening. After replacing the brushes several times, I just removed them. The robot no longer gets jammed, but I’m not receiving full benefits of my purchase. I have two cats, so the roomba has helped with the cleaning a bit, but I’m very disappointed, I would not recommend this item to anyone!

We have a Belgian Malinois (like a German Shepherd) and we tried Samsung and Shark. They could not handle the pet hair. The Shark couldn’t hold a charge long enough to do one floor. We actually had each one replaced (thinking they were defective) before we gave up and decided to put our money on the IRobot. THE BEST DECISION EVER! This vacuum doesn’t the entire lower on one charge doesn’t freak out when dealing with the amount of dog hair and it’s easily cleaned. It’s a little louder than we expected but that just translates to power to me :-) Also it was easily setup. It’s nice and sleek and fits under most of the furniture.
