Don’t think your buying experience will be any different
Reviewed in the United States on February 8, 2025
Style: Roomba j9+Verified Purchase
One star is being overly generous. I don’t write reviews, one way or the other, but this was too large of an expense not to. If it helps just one person, it will be worth my time. I purchased this unit in Dec. ‘23. I used it maybe 10 times within the first year because I found that moving all the obstacles before vacuuming was a bit of a hassle, and also it just didn’t compare to my push vacuum in performance. I did like the fact that it was able to get in difficult spots, such as under the beds. A couple weeks shy of its one year warranty date it lost its suction. After some degree of difficulty in reaching customer service, a lengthy amount of time on the phone, and photos sent via email, diagnostics were run remotely and they determined that there was an issue with the base. A new base was sent in a timely manner and they offered to extend my warranty by three months.

After setting up the new base I ran a quick run of one bedroom. The robot would not seal adequately enough to the new base to provide enough suction to empty the bin and I got an error message. Again, I went through the same lengthy process with customer service and it was determined that the entire unit needed to be replaced. My warranty on the original robot was now within a couple days of expiring so I asked if they would still honor the three month extension. After checking with supervision they informed me that since they were replacing the entire unit they would not be able to honor any further warranty on the new unit. Ok. New unit. It should last a while, right?

The new robot arrived, again, in a timely manner. It set up easily and I mapped the house and vacuumed without difficulty. A month later I went to vacuum and I got a message that the unit was unavailable because the software was being upgraded but would be available shortly. Three days later it was still displaying the same message. I rebooted several times. Nothing. I finally resorted to a factory reset and now I can’t connect to the robot at all. I’ve since done some online research and there is a definite trend here with issues occurring during software upgrades. Folks are being run through hoops via customer service only to be told that there is no fix, but…get this…they are offering 50 whole dollars toward a new unit. No joke. Check Reddit. I call b.s.

Save yourself the aggravation, time and expense and vacuum the old fashion way. This thing has not been worth it, IMHO.

Reviewed in the United States on March 20, 2025
Style: Roomba j9+Verified Purchase
I've had this robot for awhile now, so I could give it a good chance. Quite frankly, it is awesome! It does a fantastic job of keeping my floors dirt free. I have both carpeted rooms and a lot of vinyl plank flooring and it works well on both. Two recommendations... make sure you keep the dirt bin in the robot cleaned weekly, as well as the sensors behind the dirt bin and the light and camera on the front. I didn't keep the bin sensors clean at first as I didn't know they were there (didn't read the manual thoroughly) so it stopped giving me readings on product health. As soon as I cleaned them, it started working right again. Basically, keep the filter, bin, and sensors cleaned, every week or two depending on how much you use it, and it will work great! Change the filters regularly, as they can clog up with fine dust. Overall, this is an excellent machine!

Reviewed in the United States on March 21, 2025
Style: Roomba j9+Verified Purchase
I debated on upgrading from a (much) older robot vacuum and decided to give this a try. Don't regret it at all. We have a cat that is constantly shedding and, with this programmed to vacuum rotating areas of the house every day, the house stays amazingly free of cat hair and (tracked) kitty litter. Very effective on hardwood and thin carpets. Not so effective on heavier carpets so a standard vacuum is still needed there. It is a bit noisy so program cleaning when noise will not be an issue. Keep the filters clean as suction drops off rapidly if you don't. You don't need to "pick up" as it is very good a avoiding obstacles. It will, however, take a picture of said object (found a couple lost socks that way) and will ask you later if the placement is temporary or permanent. Took one star off for cost and noise.

Best vacuum I've ever owned.
Reviewed in Canada on November 29, 2024
Style: Roomba j9+Verified Purchase

I've had this for a week now and loving it. The Roomba j9 learned its way around the house initially and still seems to be getting smarter with every run. It's been vacuuming the house every morning and the floors appear to be cleaner than ever before. It gets to places the Dyson never could and even outperforms IMO. Returns to the base in another room when needed to empty its bin and again when the job is done; all without any intervention on our part.
My cat initially was terrified of the Roomba (she's scared of her own shadow anyway) but her terror seems to be evolving into cautious curiosity now. Eventually I expect they'll be fast friends.
Thinking of buying another eventually to use on the second floor.

The worst iRobot product I have ever owned
Reviewed in Canada on August 23, 2024
Style: Roomba j9+Verified Purchase
I've been owning this robot vacuum for 9 months and this is by far the worst iRobot product I've ever owned.

I will compare this product to the last one I bought, which was the iRobot i7+.

The J9+ has worst navigation.
- It invents obstacles in the grain pattern of my floor and will go around it.
- It has difficulty navigating to the right room and will get stuck and abort the job.
- It stuggles at finding its base and docking on it.

The J9+ has worst performance.
- It stuggles at vacuuming dry kitchen debrit.
- The side brush is unable to clean corners or close to walls.
- It will not pickup pet hairs from my carpets

The J9+ is louder than the i7 even on low power mode.

The J9+ has a small form factor which lets it get under my furnitures. This is a positive feature.
The J9+ struggles at emptying its bin automatically and regularly needs to do it more than once.
The J9+ keeps losing connectivity with it's base station and the iRobot cloud.

I wish I could return the product.

Smarter, more suction for carpets, powerfully handles transitions, great app -- all win
Reviewed in Canada on February 10, 2024
Style: Roomba j9+Verified Purchase
This j9+ is my second Roomba vacuum after my j5+ and was a really easy addition to the family and the Roomba app. I let the j5+ handle the main floor with its mainly hard surfaces and the j9+ is handling the 2nd floor which is almost all carpeted.

The j9+ has noticeably more suck power than j5+ and works really well on the medium and low pile carpet. It climbs room transitions with ease, eg from the carpeted rooms to the tiled bathrooms.

The Roomba neatly works around chair legs and kitty water dishes without bumping anything. No spilled water.

Regular maintenance is simple and fast. After a few vacuum runs I had to remove the side brush to untangle a cat toy with a long yarn tail. I also checked for trapped carpet fibers in the spinning brushes and found almost none.

I really love the app. I have been able to create daily cleaning schedules with times set to avoid our activity (upstairs gets vacuumed while we're making breakfast). I have it set to vacuum rooms in an order that is least likely to interfere with us even if we return upstairs sooner than usual. I added Clean Zones and a couple of Stay Away zones and now I can just let it do its thing.

No regrets on this purchase.

I love this thing.
Reviewed in Canada on August 4, 2024
Style: Roomba j9+Verified Purchase
This thing works pretty well. Only a couple of hiccups so far, trivial stuff. I have pets and the mess was constant. But not anymore. I always have my bare feet in the house and the difference is very obvious. I set this thing away every day and then once a week before I run out to town, I lift all the moveable things like chairs, ottoman, slippers and let it do its thing. Fabulous. Yes. It is loud when it empties itself, but it only does this for seconds and the end of its routine. The App is good too. Lets you customize the suction strength and how many passes etc. I like it. Once the drop the price again I will buy another one to replace my old roomba downstairs. I am almost tempted to buy the vacuum mop combo to give it a try.

It really sucks!
Reviewed in Canada on July 16, 2024
Style: Roomba j9+Verified Purchase
Truly, this thing sucks. In terms of vacuums, that’s what you want. It has good variable suction and picks up a surprising amount. It’s great at avoiding tangles and things you forget on the floor and its picture review helps define those items. Yes, the app has its bugs but overall, once automated, the bot goes on its happy little way. The noise level isn’t bad and it works out its paths fairly quickly. The base, that’s where it REALLY sucks. The vac inside of the self emptying bin is incredibly powerful. Does it empty every single thing? Not every time but it gets the bin emptied for the next job. In doing so though, a jet engine takes off. Would suggest programming it to run more daytime when not home. Now I’m looking forward to a Braava mop to compliment the vac.
