Reviewer verdict

Across 16 YouTube reviews, the iRobot Roomba Combo j9+ earns an Index score of 3.4/5, ranking #80 among Robot Vacuums. Reviewers most often praise its navigation, smart features, cleaning performance, while the most common criticisms concern ease of use, navigation.

The Roomba Combo j9+ is widely praised for its intelligent navigation and obstacle avoidance, with about 30 reviewers noting advanced mapping, camera-based precision vision, and reliable avoidance of cords, toys and pet waste. Reviewers (around 22 mentions) also highlight smart app features like Dirt Detective, voice assistant compatibility, and a pet-owner promise that contribute to convenient automated cleaning. Cleaning performance and hard-floor mopping receive frequent positive mentions (around 20 and 19 mentions respectively), with dual rubber brushes, strong suction, smart scrub mopping, and an auto-retract mop that avoids wetting carpets cited as strengths. Many reviewers also applaud the maintenance conveniences of the self-emptying, auto-refill and auto-wash dock, and its long hands-free intervals (about 18 mentions).

Criticisms cluster around the app and ease of use (about 14 mentions), with reviewers reporting a buggy or less-intuitive app, missing real-time location feedback, and occasional setup or connectivity hiccups. Navigation and mapping also drew some negative notes (about 13 mentions) where reviewers felt obstacle avoidance, edge/corner coverage or mapping speed could improve and that flat obstacles or cords still trip the robot. Mopping and hard-floor cleaning had downsides for some users (around 9 mentions), including inconsistent pad saturation, lack of fine water-level control or automatic detergent dispensing, and occasional smearing when smart-scrub isn’t enabled. Maintenance and durability concerns were mentioned as well (roughly 9 and 7 mentions), including manual cleaning required for pads, filter issues, and perceptions of plasticky build quality or scratches over time.

navigation...obstacle avoidance system could use Improvement...this model also falls behind competitors in speed ▶ iRobot Roomba Combo j9+: Ultimate Hands-Free Vacuum and Mop @ 2:56
takes longer to initially create the map and is generally slower at processing its environment ▶ iRobot Roomba Combo j9+: Ultimate Hands-Free Vacuum and Mop @ 3:01
Navigation, especially edge and corner coverage, also along furniturees is mediocre at the current firmware. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 8:11
it does not go in the back between the toilet and the wall ▶ Irobot J9+ Combo Vacuum & Mopping robot, 1st time running, m @ 5:40
it is still bumping around because I think in this video it was still mapping the house out and so it kind of bumps a little bit ▶ Irobot J9+ Combo Vacuum & Mopping robot, 1st time running, m @ 4:12
it does it avoid it every single time no nine out of 10 times it does ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 7:47
The lack of obstacle-avoidance sensors—front-mounted cameras or lasers that help the robot recognize and avoid household objects. ▶ Roomba Plus 405 Combo Review - I Really Wanted To Like it @ 6:03
the mapping was a little bit faster than like the I5 um it still took a little bit and I thought the map would just be a little bit better ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 6:55
it's still going to get tripped up on cords. It's not great at a lot of flat obstacles. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 10:17
it will just make one big room and then you have to name it yourselves and split the rooms. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 9:35
There's no way to really tune it or customize it so it can go faster. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 6:38
And the 105 doesn't allow you to add in furniture because it doesn't have a front-facing camera. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 10:06

Cleaning Performance (11)

Same thing with the iRoot i3 having two suedes and iRoot Q having a good brush. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 5:16
last place with 1/4 of the score is iRoot i3 ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 0:58
But the iRoot Q did better with the flour, but only one that left a little cornflake and oatmeal. So it's going to C. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 3:31
iRoot i3 where it just dragged all the flour along the path. And that's why it's going in last place D. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 3:23
Gap in performance between the j9 plus and the previous ioot Roomba j7 plus is not huge ▶ iRobot Roomba Combo j9+ Review: Beautiful, smart and powerfu @ 5:28
third place is Iroot I3 at C along with iRoot Q. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 6:55
The dirt mat test shows that the 505 combo can beat the 10 Max and the equally performing Combo J9 in dust collection, but falls short in bird's hand removal. It's absolutely no match for an iRoot S9 or 980 for either type of dirt. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 2:07
Vacuuming only is just bad. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 7:48
This performance is not great ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 7:38
these machines do nothing regarding dust and gaps, even with the use of mopping. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 7:50
there is still coffee on the floor. It did do a good job picking it up, but ultimately it moved a lot of it around and spread it out. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 7:34

Hard Floor Cleaning (9)

did quite a poor job and left most of the spill behind [when smart scrub not enabled] ▶ iRobot Roomba Combo j9+ review @ 6:41
it does lack a mop on option ▶ iRobot Roomba Combo j9+ review @ 9:03
sometimes the mopping pad wasn't saturated enough to completely clean a spot and it would kind of smear things around ▶ iRobot Roomba Combo j9+ review @ 6:21
I Robot chose not to include an auto mpad washing feature...you'll have to manually wash the mod pad after each cleaning session ▶ iRobot Roomba Combo j9+: Ultimate Hands-Free Vacuum and Mop @ 2:32
210ml water tank capacity, below the average for robot mops ▶ Roomba Combo J9+: Rapid Vacuum-Mop Review! @ 3:51
Regarding its mopping ability, the Roomba 405 uses two spinning mop pads that are electronically fed with water to saturate them. Unusually, the 405 does not have multiple water settings—just one water-level setting, which will be important later... it left behind a massive amount of water. ▶ Roomba Plus 405 Combo Review - I Really Wanted To Like it @ 5:19
There's no auto detergent dispenser. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 10:52
there is no way to adjust the water level. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 10:24
And the iRoot does not put as much pressure on the floor as you would like, though. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 8:12

Maintenance (9)

after a while it did actually start to smell and get kind of musty and mildewy ▶ iRobot Roomba Combo j9+ review @ 9:23
no automatic cleaning of the mopping pad ▶ iRobot Roomba Combo j9+ review @ 9:19
j9 plus vacuum only base lacks this tray ▶ iRobot Roomba Combo j9+ Review: Beautiful, smart and powerfu @ 4:30
unable to empty bin uh clog ▶ Irobot J9+ Combo Vacuum & Mopping robot, 1st time running, m @ 8:52
I had to take and reill uh the water tank I had to dump the water into a container the water in solution and then um fill the tank with just water and rinse rinse it out kind of shake it a little bit and I also had to do that with the tank in here just to she said the sensor sometimes new robots they need to be um they're stuck just because it's been sitting ▶ Irobot J9+ Combo Vacuum & Mopping robot, 1st time running, m @ 4:52
So, you're going to want to clean that manually. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 11:13
these filters are not washable I wish they were washable ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 4:20
I don't know why these have these rumas have a hard time emptying everything ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 4:06
these things just get extremely dirt I can never get 60 days out of this filter ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 8:18

Durability (7)

The iRoot, the plastics are going to feel plasticky. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 3:10
if you look at mine, they have scratches all around them cuz these are going to be additional bump and run. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 1:08
On the new iRoot, the build quality is subpar, at least relative to the competition. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 5:17
And the build quality is not as good. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 13:43
They're not reinforced, so you can knock this over if you try hard enough. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 12:10
this is kind of like a flimsy cat food container here. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 5:47
The iRoots just looked better overall. There were more catches, there were more unique features, even the construction of the unit looked more solid than what you're getting now. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 5:30

Overall (6)

And no extras for the iRoot. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 6:21
not the same for the two i robots which a lot of people are upset about. So who knows what iroot is thinking. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 5:38
And iroot i3 has it but not the queue ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 5:48
I robot. Oh my god, what was that? ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 1:10
missing a few features like automatic mop washing and drying mop extension and better side brush reach ▶ iRobot Roomba Combo j9+: Ultimate Hands-Free Vacuum and Mop @ 3:51
these Roomba just seems behind the power curve ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 7:16

Carpet Cleaning (6)

When cleaning the blue fluffy carpet, the results are even inferior to the already rather poor cleaning performance of a 10 Max or combo J9. We also have no gains after seven cleaning runs, leaving 61% of the test dust in the carpet. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 2:26
the 505 combo can't keep up with the red carpet cleaning performance, and it can't even reach the poor standards of the 10 Max or combo J9. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 2:47
The 505 combo was not able to remove the fibers even after four passes, while the tested S9 and the 10 Max had no issues to remove all fibers. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 6:18
Compared to the older iRoot models, the single structureless main brush is also in disadvantage regarding fiber removal from carpets. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 5:58
the overall carpet performance is not great and the 505 5 combo got outperformed in many cleaning tests. ▶ iRobot Roomba Plus 505 Combo - cleaning performance review @ 5:38
the carpet deep-clean test—where we see how good they are at picking up deeply embedded debris, such as sand—the Roomba 405 was significantly below average: by far the worst score we’ve ever seen from a Roomba. ▶ Roomba Plus 405 Combo Review - I Really Wanted To Like it @ 4:47

Other (6)

This is bare bones where it's going to be fitting. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 4:46
So now they're not using their patented brushes anymore. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 3:54
But I wouldn't say this is going to be next generation or cutting edge in any sense. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 4:56
And I think that's one of the reasons why it doesn't perform as well as what we had previously known from iRoot. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 4:30
once in a while you got to reinstall it ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 10:01
the Roomba app is okay it sometimes it lags sometimes you got to reboot it ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 9:58

Noise Level (4)

fairly loud when you set it to its highest suction setting ▶ iRobot Roomba Combo j9+ Review: Beautiful, smart and powerfu @ 4:21
startlingly loud ▶ iRobot Roomba Combo j9+ Review: Beautiful, smart and powerfu @ 3:56
I'm predicting that it's going to be a lot louder than you think it is. ▶ What HAPPENED to iROBOT? - iRobot Roomba Plus 505/405/105 Re @ 12:33
that auto empty is very loud they have not improved that a whole lot ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 4:38

Suction Power (4)

And the iRoot Q, but I don't know if it's just me, but I couldn't really get it to change the speed. ▶ iRobot Roomba Combo j9+ Review 🔥 Best Robot Vacuum & Mop 20 @ 4:25
Max suction power (Pa) not published/available ▶ Roomba Combo J9+: Rapid Vacuum-Mop Review! @ 0:40
Max CFM below average (although highest for a Roomba) ▶ Roomba Combo J9+: Rapid Vacuum-Mop Review! @ 1:04
Though, as I said, it was good at picking up debris on the surfaces of floors, it didn’t do so well with some of the other performance metrics. For example, its suction power and airflow were both below average on max power ▶ Roomba Plus 405 Combo Review - I Really Wanted To Like it @ 4:22

Value for Money (3)

much more expensive though to the point where it's really not a good value ▶ The Best Robot Vacuum Tier List @ 6:55
the high price ▶ iRobot Roomba Combo j9+ review @ 9:32
would I spend $800 on this no ▶ iRobot Roomba j9+ Self-Emptying Robot Vacuum Detailed REVIEW @ 11:06

Pet Hair Removal (3)

struggled suctioning up finer pet hair out of plusher rugs and left quite a bit behind ▶ iRobot Roomba Combo j9+ review @ 9:06
slightly less Adept at getting the stubborn pet hair that tends to congregate on rugs ▶ iRobot Roomba Combo j9+ review @ 8:02
it performed poorly in the 2½-in. flattened-pet-hair-pickup test, where it got the lowest score we’ve seen yet, effectively picking up only about half of the hair on the carpet. ▶ Roomba Plus 405 Combo Review - I Really Wanted To Like it @ 5:01
