I still have the 980 and I think its amazing as a vacuum even though they discontinued cloud support. I also have a J9+ combo which I supposedly upgraded to a few years ago and its complete crap. It couldn’t find the base, it couldn’t refill the water tank. I ran the 980 after the J9 and it vacuumed a lot of stuff that the J9 missed. Irobot isn’t what it used to be. You don’t see it talked about because it’s bad now

It's odd how navigation has became their weak point. I have a J9+ Combo and kept it upstairs because it picks up from carpet better than my actual vacuum did, but the much cheaper Ecovacs I have downstairs has way quieter modes and does the job in half the time. I will also credit the Roomba at being way better at both object avoidance and untangling itself, whilst being way worse at finding it's way in to spaces it then can't find it's way out of.

I have only had it about two weeks but the ecovacs deebot x11 has beautifully managed my Bernese mountain dogs fur that I used to have to vacuum twice a day for. Previously had the iRobot j9 combo that could not cope at all with it. I do run the x11 twice a day to keep up. We also have a longhair chihuahua and two British shorthair cats.

I like the Roomba j9+ Combo for its design. The base looks aesthetic. The hardware is well designed. The app is good and easy to use. I run it daily for vacuuming and mopping and it keeps everything nice and clean and dog hair free. I would suggest considering two for upstairs and downstairs because the whole point is that you can automate it, to make your life easier.

Roomba combo j9, It does have it's germlings \-doesn't like back out the bay onto the carpet sometimes \-random midnight activations \-the app is very finicky about when the wifi connection to the roomba works But, it does a way better job then me cleaning consistently so i'm very happy with it. though, fuck roomba and their expensive bags, I just empty the same bag over and over again

I agree with others above. Suction power really doesn’t make that much difference. Airflow and roller design make far more difference. I have a Roomba combo j9+ and it is great at vacuum with lower advertised suction but the dual roller really does clean the carpet effectively. I have a Narwal Flow that is fantastic for mopping but not quite as good for vacuuming (though for my house it’s mainly tiles downstairs so that’s not so important) These vacuums are all about compromises I believe. One may be good at one but not necessarily good at the other. Still looking for one to do it all.
