"super easy to get long hair out of the rollers/wheels/whatever. ... Wife went through chemo and it was a test for the robot...both survived!"
"The dual rollers, bin design (reduces filter clogging), dirt detection, and bin sensor for auto empty make it well suited for pet hair."
"VacuumWars recently found that the similar combo 10 max picked up 100% of 2.5 inch hair from carpet, which was much better than many modern flagship models from competitors."

"it doesn’t matter when the roomba takes care of charging as needed on its own with the dock, so it’d be pretty tedious. ... powering and emptying themselves as needed."
"The dock holds a lot of dirt (weeks worth, certainly) and the vacuum itself doesn’t hold much, so you’d have to be manually emptying it all the time. ... powering and emptying themselves as needed."
"they do a decent job cumulatively keeping your floor 80% clean when they can frequently run themselves unattended"

"iRobot was a no-brainer in this part. ... No prep is needed. Just hit the button and it vacuums everything and avoids every small item like a phone cable or a sock."
"The later Roombas with a camera/vision system are pretty good at avoiding things that could cause snags/clogs. ... I used to be vigilant with clearing the floor and even putting dining chairs on the table, but now I just have my Roomba run every night with dog toys, kid toys, wife's shoes and purse, chairs, charger cords, laundry baskets, and everything else blocking its path."
"I have owned both the roomba j series and dreame l series, and both are so so much better."

"I run mine at least 2 times a day and I think it helps keep it where hairballs don don’t build up and get stuck in it."

"J8+ barfs hair clumps over one of our rugs ... My J8 leaves hair clumps even when run daily. ... If I run the vacuum every day it’ll do the rug just fine. May leave 1-2 ropes. If I don’t run it every day, there will be more. ... The borders of the rug is where there are always ropes. ... I can run the robot twice and there will be ropes. ... I can run the Dyson then the robot and there will be ropes. ... I can pull the edges up, dyson under the rug, then Dyson the entire top of the rug and the robot runs—guess what I get along the edges? Ropes. ... However in real life my J8 is a fail in this use case. ... J8+ is meh for Pets. ... the j8+ barfs hair clumps all over one of our rugs."
"it’s a machine that doesn’t have enough suction. ... the robot runs along the edge and there is a gap that it doesn’t have enough suction to pull a quarter ounce rope of dog hair."

"it bumped forward practically and always against everything. ... The camera detected neither obstacles nor objects."
"their navigation was supposed to be smart but turned out to be weak and lost maps..."
"It kept on having problem docking"

"God forbid when you are training the ai(?) by reviewing the photos you ever allow anything as ... not an obstacle ... then it will run over similar things forever. Like string, after I told it a cord off the ground was not an obstacle. :("

"I spend 3-4 minutes putting things like litter baskets and chairs up off the floor so it has a better reach, then schedule it to run 3x. Then turn the schedule off again and return loose items to the floor."
"It took some prep to make my home ready for it--furniture needs to be high enough (and legs wide enough apart) for it to run up under. ... Lamp cords need to be secured."
"Do clean the hair out of it after it runs (takes only a couple minutes). ... Spend about a minute getting hair out of its rollers."
