Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers have expressed concerns about the durability of the robotic vacuum cleaner. They say that it is fragile and easily damaged by things like a/c vents and floors. They also say the rollers don't last and the finishes on all the furniture are getting damaged. Customers also dislike the value. Customers have mixed opinions on ease of use, performance, suction, accuracy, and cleaning.
AI-generated from the text of customer reviews
Customers are mixed about the performance of the robotic vacuum cleaner. Some mention that it works pretty good, is fairly thorough, and is smart, while others say that it doesn't work for very long, and has failed to complete a job since early February. The performance of this robot has only gotten worse, and it has lost the ability to use the Eco Suction setting.

Customers are mixed about the cleaning of the robotic vacuum cleaner. Some mention that it does a better job cleaning, has better mapping, and is easy enough to clear the bin. However, others say that it has never cleaned their living room completely without errors, the cleaning pattern appears random, and sometimes missed the most basic dirt. The brush does occasionally get clogged with pet hair and slow down or stop the brush.

Customers are mixed about the suction of the robotic vacuum cleaner. Some mention that it has very powerful suction, while others say that it gets stuck a lot. It gets stuck on the legs of a baby's bassinet, in between chairs or tables, and on the rug. It also gets caught in curtains and cords. It regularly gets stuck under kitchen and bathroom cabinet bases, and sometimes gets trapped in the office.

Customers are mixed about the ease of use of the robotic vacuum cleaner. Some mention that it has been reliable and virtually trouble free, while others say that it gets stuck and needs assistance a lot. The app is confusing and the robot is extremely finicky about the placement of the home base.

Customers are mixed about the accuracy of the robotic vacuum cleaner. Some mention that the Rhoomba does an amazing job mapping out the house, avoiding obstacles and allowing you to clean only specific rooms. However, others say that the mapping algorithm is horrendous and very dependent on the user to accommodate it to their home. The factory reset is that you lose the map of your home during the process, so the robot loses its bearings and screws up the map.

"...could make it back to base because the battery was low and it had a navigation issue ( again..lost). - My roborock never once had this issue..." Read more
Customers are not satisfied with the value of the robotic vacuum cleaner. They mention that it is an expensive vacuum, the replacement rollers are very expensive, and the batteries are a bit too expensive. They also say that the bags are small and expensive, making it difficult to clean the vacuum. Customers also say the rollers and batteries are not reliable enough for the money they are paying for it.
"...Cons:• Price. No way around it, this is an expensive device to vacuum the floor...." Read more
"...To repeat many other reviews, this is a pretty flawed expensive device...." Read more

Customers are not satisfied with the durability of the robotic vacuum cleaner. They mention that it is fragile and easily damaged by things like a/c vents on the floors, rattles, and the rollers don't last. The finishes on all the furniture are getting damaged as well as the machine from running it 5 days a week. The robot broke after less than six months. The roller brushes get worn out if you have people with long hair in the house. The side brushes appear weak.

Pros
- Cleans in a grid pattern - see photo of nice lines left in carpet
- Travels from room to room whether it's over carpet or vinyl.
- Has good suction. I have thick/dense carpet and it does a good as my stand up vacuum
- Very thorough. Does a good job of going around table legs (see photo with circle path around table leg) and even underneath couches that have a flap at the bottom
- Can work in connection with the Bravva mop
- You can direct it to clean specific rooms and stay out of others
- When you select the rooms you want to clean, it gives an estimate of the time it takes to complete it.
- You can choose from 3 suction levels
- It empties itself, so no handling the dust can
- No bad smell like my old vacuum
Cons
- Some rooms it vacuums against the grain of the carpet. For one room, I was able to place a divider in that room using the app so that it mapped the room differently.
- It has had about 3 tech glitches, but that is expected because tech isn’t perfect. I either rebooted the bot, closed and reopened the app or gave it time to sit and then it worked properly.
- When it does the hallway it goes over the thresholds to get the edges and slightly enters the other rooms. This is a con if it goes into a room where you don't want to be disturbed or go into a room where it gets stuck. So you h have to remember to close the doors. The only threshold that it has a problem going over is the bathroom (that threshold needs adjustment, not the bots fault) and if it's cleaning the hall it will go over it and then can't drive back out. There is a setting that says to get as close to the edge without touching edges but I haven't tried it yet to see if that helps.
- October 2023 Update -
Overall I'm still happy with this but since writing the initial review the vacuum has been giving me a bin error regularly since mid-September even after it is thoroughly cleaned. The app says they are working on a fix coming out in Oct but I've yet to see it happen.

While it is loud when cleaning your floors there is nothing that compares to when it empties into the base. High pitched vacuum noise as loud or louder than my shop vacuum. I am not exaggerating.
I had a $180 Shark that was dumb as a rock, banged hard into everything, not as loud and cleaned as well. This is supposed to replace the Shark.

On the Seventh day...
After it woke me up it vacuumed for a bit and did it's 'I stopped vacuuming for a reason' beep. I had some things to do so I checked the app. It showed it was still cleaning. But it wasn't.
Eventually I remembered it exists and found it. I pressed clean and it would not resume. So I put it on the dock and it still showed it was cleaning as it was charging.
Came back and the Roomba didnt respond to either the app nor the 'clean' button.
It needed a reboot. Held the 'clean' button for 20 seconds and it rebooted. Still nothing. I waited again. Pressed the 'clean' button again and it finally started to reboot. It told me it had an error 15, some internal error it was able to clear on its own. But no clue what it was.
Finally it starts working again and I set it to clean again.
Seven days and this thing already had an internal error. $600 gamble if this will happen again. I'm going to exchange this one. I don't feel like dealing with a deteriorating unit which may fail outside of the 30 day azon return period and get a refurbished unit from a warranty return with iRobot.
Update: Since I posted I still ran the vacuum to see if things that happened were a fluke. Maybe my expectations were too high? I've come to find out they really aren't.
So, the vacuum tried to 'mount' the dock. No, not in the I'm going home to charge and empty my bag. Nope, it decided to hump the dock at an approach angle of 45°, then after a minute of rocking up and down it backed off, spun around 360° and started it again. This happened 4-5 times before I picked it up and placed it away from the dock.
Something else I've learned is that everytime something gets stuck in the brushes I need to clear the brushes and then put it back on the dock to 'reset' it. Pressing the clean button will not get it to start cleaning again. It just toots its cheery little tune and sits there. I did not have this problem with the Shark that the Roomba replaced.
The worst part of it is that after being on the dock it will not pick up the job where it left off. So half the floor is clean. If I set it to clean again it starts with cleaning the area it has already cleaned.
I run this vacuum once a day. I can count on my hand the number of days that this vacuum has run trouble free for me and still have 3 fingers left over.
Update, again (2 months): Do not buy this junk. It literally said it was stuck on a ledge... In the middle of our hardwood floor. Nothing around it.
Now it has taken to trying to empty it's bin before it starts a job, repeatedly. Today it was 3 times in succession before I pulled it off it's dock. What programming says keep emptying your bin multiple times before you start a job. And the vacuum's bin is already empty. Who programs these things?
------------
Update 11/24/23
It is officially no longer working. It had a fault stating that the bumper was jammed and to tap it a few times to loosen it. I tapped it, and tapped it and tapped it some more. No change. Put it on the dock. No change. Rebooted it. No change. Tapped it again. No change. Rebooted it again. Yes, finally change. It moved a few feet from the dock and spun in a circle for about a minute and then the error of stuck bumper is back.
I give up.
I will continue to update all the new faults I discover until Amazon makes it unable for me to edit this review.

Top reviews from other countries
1) The quality of customer service at iRobot is unequaled. 2) I recently tried another product that was supposed to be the best according to PC Magazine. This other product was finally very disappointing. In particular, iRobot was far superior to make a map and this other brand, which claimed to wash the floor at the same time, still has work to do to fill its promises.
Review when I purchased it:
iRobot Roomba s9+ takes some time to map the floor, and it doesn't always do what we think it should do. My advice is : leave it alone! Let it do its work and clear the place as much as possible. Press the map button, then the 3 dots, then mapping run. Do it at least 3 times (you have to do it at least 3 times). This will take a lot of time (for 1500 sqf). Let it work! Thereafter, this device will work perfectly. I am delighted.
N.B. The first time, I left the chairs and other little things (flower pots) in their place. I was disappointed with the result. The plan wasn't perfect. The second time, I took as many things as possible off the floor and put them somewhere else. After giving an almost perfect floor... I had a perfect plan! If you are demanding with the robot, you must give it what it needs to meet your requirements.
