"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."
"The Roomba is fine for keeping visible areas tidy ... one pass on the floor and the internal bin will fill with fur and dust. ... 3 dogs, a Basset, a Lab, and a Terrier. All are moderate shedders and fur accumulation is a problem. ... We’ve used a self emptying Roomba for years."
"for dirt/hair maintenance it is wonderful."

"We have three kids, two dogs, and a cat that sheds more than both dogs combined, and having robot vacuums has been a game changer. ... But the robot keeps the main areas of the house from getting hairballs and dirty."
"I've had my roomba for like 5 years now.. We have 3 big dogs and a cat, in a small house. Still works great, I've replaced the brushes and obviously the filters on it but it still works awesome."

"It runs daily at 9:30 am, recharges and empties itself, then finishes rhe rest around 2 in the afternoon. ... That robot is a wonderful thing."
"We run the vacuums & mop anytime we leave the house, and it’s so nice coming home to freshly vacuumed and mopped floors!"
"It is such a nice time saver. ... We run it three times a day and it really helps with upkeep."

"we got the one that can "see" poop and avoid it so it doesn't track it everywhere."
"But I do like the obstacle avoidance."
"Irobot has a camera for object avoidance. I think it works pretty great."

"I upgraded to a roomba with the self emptying thing and I love it."
"Now we have two good ones (iRobot) with the bin that they self empty into when they get full. ... Before we got the one with the bins, it would get full and need emptying before it finished a whole cycle. Now it goes and empties itself and then goes back to cleaning."
"Self emptying is the best upgrade ... haaaated emptying that thing constantly"

"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."
"Currently have a Roomba j8+ which struggles with the pet hair"

"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. :("

"another that supposedly maps the space. The cheaper, random movement robot is vastly superior in all ways."

Pajamapadge 1.0We just need something that's 'as good as' our Roomba J8+ on carpet, but doesn't spin in circles like a loon and need to be rebooted all the dang time. A lot of VacuumWars ratings list newer vacs with much lower carpet cleaning scores so I've no idea what would be better than and more reliable, than what we already have.
Fickle-Strawberry521 0.5I just returned the iRobot J8 Roomba that I bought 15 months ago. It worked fine until the last month or so. It would start a cycle and move out a few feet and then just spin in place until I paused it. I was unable to get it to start over again. I cleared it electronically and re-set it up over and over again and it just kept doing the same thing. Luckily, Costco refunded the $500ish we spent on it in June 2024. I am starting to research other brands. does anyone know about Samsung or Dyson? Thanks in advance.
FRCP_12b6 0.5I have a iRobot j8+ from Costco. Works great for my needs. It only vacuums and has auto-empty and obstacle avoidance.
LoveOfSpreadsheets 0.5We have the Roomba j8 from Costco. The first one was flaky so we went and exchanged it and the replacement has been solid.
ResistHistorical2721 0.5Same for my j8+, it avoids cables, then asks about them in the review step.
Revlis-TK421 0.5I have a Braava M6 that runs after my roomba j8 runs. I'm relatively happy with the pair. I kinda wish they could share maps but whatever. My gripe with the mop bots is they dont have the equivalent of the vacuum's waste bin station. If there was a way to auto-clean the pad and auto-refill the water tank, I'd be in hog heaven.
rishmanisation 0.5Tell me if I made the right choice! I have a 1 floor 2.5 bed (2 bedrooms + office) 2 bath which is mostly vinyl (bathrooms are tile and my walk in closet is carpeted); live alone but have a dog who’s a massive shedder. There are transitions between the bathrooms and other rooms but not otherwise. Went with the Dreame L50 Ultra; other things I considered were the L40 Ultra AE, Roborock QRevo Edge and the Eufy E28. Currently have a Roomba j8+ which struggles with the pet hair and also doesn’t mop.
su_A_ve 0.5Should I mention that I’m getting a Dreame Govac 508 soon and hoping to do this. Had an iRobot J8+ with the separate mop bin and that’s what I would use. But since that was self contained it’s a different story.
ZeroWasted 0.5I have a Roomba j8 for vacuuming and a braava for mopping. I opted to buy them separately because I feel like it's less likely to have something weird break on them. I love them. They have great mapping and they are made to avoid pet messes. They send you some images when it finishes so you can go over whether or not it was a pile of dog shit or a scrunchie that shouldn't have been there. You can then have it go back over that area after you pick up the shit or scrunchie. Costco usually has the Roomba for a great price if that's an option for you.
BardicKnowledgeCheck 0.2Irobot has a camera for object avoidance. I think it works pretty great. It worked perfectly in the beginning, but 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. :(
