I have 4 dogs and have a J9+ vacuum only version and am extremely happy with it. Just keep up on maintenance and cleaning it and it will do a great job.

I'm interested if anyone has a positive recommendation. I have a roomba J9 and I have tested by running my Shark NV752 TruePet immediately after the roomba, it picked up soooooo much more pet hair even after the roomba went over it twice.

I don't know about the new lineup, but nothing beats a Roomba 9-series on carpet, though. Even on hard floors, my Saros 10 misses a lot of spots that my J9 never did.

There are a few compromises to be aware of. I've had a Saros 10 for almost a year, but I still send my Roomba J9 out once in a while to clean up what the Saros misses. I also have the Narwal Flow, Roomba 705, previously had Dreame and Ecovacs, and nothing can clean tight around chair legs, round table pedestals, etc. as well as the classic Roombas. Roomba roller brush design also picks up hair, fur, and fuzz on rugs much better than any other brand, regardless of reported power. Also, LIDAR-based robots won't clean under curtains or bedding like classic Roombas could. I'm only aware of Dreame/Mova having a setting to accommodate this. The Roombas (old and new) also have more advanced voice control via Google/Siri/Alexa that allows just vacuuming, and can specify zones in addition to rooms. All other brands can only "clean" which wastes time and water when you just need a quick vacuum. Also, the Roomba app is just way more efficient to use. Not saying the move isn't worth it overall, but there are some sacrifices to be aware of.

irobot roomba j7+ is quiet and has great avoidance system. the next one, j9 is more powerful so it’s louder sometimes.

I would recommend a roomba model that detects stuff, from a J7, J7+ to a J9, J9+ (the do detect pet "presents"😅) not the J9+combo, (that units dock had plenty of failures) I would also go for a Plus 505 combo if you also want to mop the floor, because It has the laser view but also a front camera. J7 J9 send pictures of obstacles and asks you if they're permanent or not, you could ask an AI to compare those models to better pick what suits you best, hope I've been helpful.

I have a roomba j9 and a Roborock s7 MaxV they do an okay okay of keeping up with one shepherd. Any top of the line unit should work just expect to fork over a good chunk of money. I know they Roomba “j” series gets a bad rep but I think they are great (yeah not as quite or fast as other but can be found a lot cheaper) what ever you do get a robot with a self empty base

We have a roomba j9, no mop. 2 husky mixes. We constantly have to empty the roomba bin but it does a somewhat decent job of keep the hair at bay. We need to vacuum EVERY single day otherwise it looks like tumbleweeds of hair. 1400 sq ft house, and we have very very low pile rugs. It doesn't replace vacuuming but helps. We opted for the one without the mop because I don't trust anything with water if I'm not there. Plus I don't want the dogs walking on what was just mopped.

Get one with an empty dock. I have an old Roomba (J9) that used to be my main robot for the entire house, but now it lives in my upstairs office. I barely have to do anything to have freshly vacuumed floors every morning. If I had to empty it daily, I wouldn't run it daily as I'd get annoyed, or just forget.
