Roomba does not have LIDAR navigation. I do have another robot that is LIDAR so I can give a rough pros and cons of the two type of navigation system.
Roomba relies more on bumping into things and it's map to navigate. There's good and bad. The bad is that it will often go around the house as if it's a drunk bumping into furniture and objects. The robot needs to learn your floorplan and that can take a long time since it's bumping into everything. It took me about 5 runs of my whole house. Each run took about 3 -4 hours since my house is 2500 sq ft. Prior to it learning my house, it's navigation looked like it was non existent. I thought I had just bought the dumbest robot especially compared to my inexpensive $300 LIDAR robot. However, once the robot declared that it had learned my floorplan everything changed and I began to see the benefits of the iRobot navigation system.
Even after learning my floorplan, the iRobot still takes forever navigating around table and chair legs. Bumping and taking multiple attempts to escape the forest of chair legs, but surprisingly, it has never gotten stuck in my house. I have set it to vacuum my entire house several times and in total it has vacuumed about 20,000 sq ft in it's lifetime so far and it has never gotten stuck. We have kids so there's a lot of toys and miscellaneous items everywhere so that's amazing to me.
My LIDAR robot on the other hand navigates beautifully around furniture but it can't see cords or other lower to the ground objects and it constantly gets stuck on these objects. Also because LIDAR isn't bumping into things to navigate it gets stuck under my couch because the fabric under my couch sags and the LIDAR robot will travel underneath the couch but then think it's blocked in by the fabric when it tries to leave the couch area. The iRobot doesn't have this problems because whenever it's in doubt it just goes barreling through and utilizes the bump sensor to feel around.
The other problem with my $300 LIDAR unit was that it would sometimes do a cleaning run but mistakenly think that there is a new floorplan and erase the old one. It's more sensitive to changes because it's LIDAR hardware can detect small changes. This is probably more a software issue. The iRobot on the other hand, is very hesitant to change it's map. That is good in that it has never erased my current floorplan or made incorrect modifications, however, the initial "learning of the floorplan" is a bit harder if it doesn't discover all your rooms. Getting it to discover new rooms is more difficult since the floor plan is locked in. I've found the best way to get it to discover new rooms after it has "learned the floorplan" is to do an area clean and just draw a box where to new room should be. Once I did that, it would explore that area and declare it found a new space and then it was added to the floorplan.
A few other more minor issues is that the Roomba software is polished but also very limited on options as compared to my inexpensive LIDAR unit. For example, I can't set how often the Roomba should self empty or the quiet times (they removed the beta feature for quiet times). These are important features since the self empty dock is very loud. Much louder then my LIDAR robots self empty dock. I'm not that sensitive to noise. The noise level is just a design flaw. I can't imagine going forward they will keep this design. If you live in a small apartment then you should definitely be aware that you will be disturbing your neighbors or yourself when it self empties. It's louder than my large shop vac.

Good But Some Glitches
I got this J7 plus on sale for $599 so for what I paid it's a really decent vacuum. I've owned a lot of iRobot Roombas for the past 20 years so I consider myself sort of an expert. Also keep in mind I do not hand out 5 star reviews lightly. This one gets 3 stars because I had some issues with the app, and getting it set up. I also can not use the function where you look at the photos with my iphone 11 pro max. I was finally able to do the set up using my OLD ipad air 2. I find it unacceptable that the app will not work for one of the main features or to set it up, using my newish Iphone on the latest iOS software. In talking to other users this problem is common. Had I not had the old iPad I would have had to return it because without connecting it to wifi via the app, it's worthless. Once I got it set up, I can do the schedule etc from my iphone but it won't show me the photos for the obstacles it finds. I get the error message on my phone but if I open the app on my iPad I can see the photos and deal with them. I do not like that I have to go get out an old device to do it and do not understand why iRobot does not deal with it. I also tried to contact them about it and got no response. I might end up just turning off the feature because it's not that big a deal to me. I did try turning it off and was hoping it would shut that light off but the light still is shining even with the feature turned off. It seems like it would waste power having that light on all the time and if I don't use the feature why is the light still on?Ok so on to the actual vacuuming. This model does an great job on hard surfaces but does not really do the greatest job on carpet compared to my older 980 which had a carpet boost setting that most of the other 900 robots lacked. I also liked that I could set my 980 to focus on cleaning and could turn off edge clean. It's probably silly on my part but I like to see the neat lines on my carpet after it cleans and it seems to do the back and forth cleaning with the j7 and then go around the edges so I see these deep marks on the edges and going around any furniture. I liked that I could turn that off with my 980 so I just saw neat rows. I could always go turn it on once in awhile but honestly that edge feature is more important with hard floors, than it is with carpet.One other thing I find odd is that the app shows me carpet the robot has detected, yet there are no settings for changing vac power level and it does not act differently on carpet, so why is the thing worried about detecting my carpet?I ended up having to set it to clean twice once one way and once across what it vacuumed to get it as clean as it got it with my 980 alone. I probably would have been better off going with the s9 for carpet but I did not want to pay that much and upstairs there is not as much dirt so it does and acceptable job. I just think they could have given it a little more power and more settings. on vac power.I love that I can set it to do certain rooms, and no longer need those dumb walls. In that respect it's so much better than my 980.One other thing it seemed my 980 did better with was area rugs in the bathroom. My 980 used to knock them around a bit but did not get stuck on them. The j7 gets hung up on the little cotton rugs on the floor. I'm not sure how I'm going to deal with that. I want it to clean our bathrooms but it's a pain to have to pick up the rugs each day so for now I turned off the bathroom cleaning.The self emptying feature is great. I do not have to empty the bin and once I do have to empty the bag it seals and goes in the trash without me having to get a puff of dust all over. I also love that they lowered the height with this self emptying bin so it's not a huge tower. I've been running it 3 times a week upstairs for over a month and have not had to empty it yet. I'm thinking I might just change it at 2 months if it does not give me a notice that it's full. I can feel stuff in there but I guess there is room for more. I'm not sure what has to be in there to trigger it needing to be changed. The bags to me seem reasonable. Even the irobot bags are only around $5 a bag which seems reasonable considering I'm not having to change it often, and it's worth it for me to not have to deal with the dirty dust puff all over my cleaned area. It makes me want to upgrade my s9 to the self empying base and I might do it at some point if they lower the height of that self emptying base too.Over all this is a decent robotic vac. It's great if you have hard floors but with carpet it's just so so. I'd prefer a deeper vac power for carpet, but it's passable.Thanks for reading my review
