"No more dog hair tumbleweeds!"
"I can confidently tell you that the Roomba j9 or 10 max is by far the best. ... They stand out because I never see dog hair on my carpets when they run in contrast to older Roomba series and other brands."
"Our J9+ Vacuum only device is amazing at keeping our floors and air clean. ... It runs daily, sometimes the master bedroom needs twice because all it takes is one Bernese wrestling match to leave hair everywhere 😂. ... My settings are 2 passes and high suction."

"My home is mostly hardwood and two area rugs. It does all 95 % better than I can any given day!!"

"Comes with a base station that it blows the content into. ... Super low maintenance that way."
"my roomba with self-emptying base is a - and I cannot stress this enough - fucking lifesaver. ... I owned one without the self-emptying base thing and I never used it because emptying it every time it was full was a barrier I wouldn’t get past. Getting the base where the roomba empties itself is a GAME CHANGER."
"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."

"It’s the best at avoiding dog poop. ... They have the best obstacle avoidance for poop ... it really does do a phenomenal job at avoiding pet waste ... You can’t reccomend Roborock when their top of the line six months ago consistently runs into dog poop."
"It’s the best at avoiding dog poop. ... They have the best obstacle avoidance for poop(check a video I have on my account of the Roborock Q Revo Máster plowing through fake dog poop. Also for under 500 the obstacle avoidance won’t even really work with my experience. ... Their obstacle avoidance is decent but it really does do a phenomenal job at avoiding pet waste which is what matters most."

"I would recommend nobody buy a robot vacuum without Lidar at this point. ... I've used two different Roborock systems dating back 4-5 years and are still superior to iRobot's new stuff with only camera based detection and mapping systems. ... My J9+ literally gets lost in its own map and struggles to navigate at times. ... Sometimes it wanders around with an error in the app until it redocks and restarts cleaning."
"It took some weeks and several "mapping runs" for it to finally figure things out, and then it broke and needed replacing. ... It was very frustrating to get working"
"I have a roomba we named homewrecker because it leaves a trail of destruction behind it. ... It always knocks over something or gets tangled up in wires."

"My roomba combo j9+ wouldn’t properly saturate its pad with my floor type"
"for the love of God please don get a roomba combo model. They don work… ever."
"They don't seem to have enough traction while mopping even on their lowest setting and using plain water, it'll just start sliding and not go in a straight line. Then it'll give up and be in the middle of a room."

"the brushes pull up some of the moisture from the mop and then dust will clump up along with pet hair and clog before getting into the bin."
"it starts just wadding up hair and leaving it in chunks"
"I feel that this model needs better anti-tangling tech to be more competitive"
I can’t blame you. When the Max 10 or Combo j9+ work as they should,…….they are really great products. I run two Combo j9’s and a plain j9+……in a 1700 square foot rancher. I’m OCD. Love em. Love em.
r/roomba • Roomba Combo 10 Max - I kind of love it? ->It’s way quieter than the Roomba J9+ and the Shark IQ. Those both sound like jet engines.
r/RobotVacuums • Personal review: Just got my Eufy S1 Pro - very happy! ->We use a Roomba J9+ for this use case and it does well.
r/RobotVacuums • Best vacuum only (no mop) robot vacuum for hardwood, tile and one low pile rug? ->The combo has a mop, but you can buy the non combo version that is just a vacuum.
r/RobotVacuums • Best vacuum only (no mop) robot vacuum for hardwood, tile and one low pile rug? ->I have 4 dogs so feel your pain, also 3 Women in our house so hair is a problem. I don't have the eufy S1 yet, but I think the Eufy X10 Pro is great but it doesn't get much love here. Also the Roomba J9+ vacuum only robot is fantastic.
r/RobotVacuums • What robovac would be best for 3 long haired dogs? ->I have 4 dogs so I understand the issue well. About 3 months ago or so I upgraded from my trusty i7+ to the J9+ vacuum only version and while I was happy before I couldn't believe what a huge upgrade it was. It runs quite a bit quieter, the suction is far more powerful, a large battery that will do my house in one run with many other upgrades that made this device worth it to me. I was able to get it on sale for I think $300 off so that helped my decision also, so check for sale prices. You already have a Roomba so I'm sure you are aware but maybe for others who might read this just know that it can take several runs until it reaches a baseline clean so expect to have to pick up clumps of hair and clean the rollers, wheel and side brush after every run until it's just everyday maintenance. I can skip one day but any more than that and it's dog hair chaos! I love how much it helps with keeping dust down and the air much cleaner so I'm not seeing nothing but hair floating around in those spots of sunshine in the house 😃
r/roomba • Best roomba for dog hair and switching from hardwood to low rugs? ->You can never have too many dogs 😉 Your advice is solid though. My J9+ vacuum only keeps our home clean with our dogs. 🐶
r/roomba • Help buying the right Roomba ->Hiya, we have Bernese mountain dogs, a Westie and just lost our Corgie recently 😔 Our house knows a thing or two about dog hair. Our J9+ Vacuum only device is amazing at keeping our floors and air clean. It runs daily, sometimes the master bedroom needs twice because all it takes is one Bernese wrestling match to leave hair everywhere 😂. My settings are 2 passes and high suction. Maintenance is key, especially with pets! I remove hair from rollers daily, and each weekend I do a more thorough cleaning like blowing out the filter with an electric air blower, removing the front wheel and clearing the hair, removing the plastic caps from the end of the rollers to clean the hair from there, wiping down the charging contacts, which takes less than 5 mins. This will keep your device, and you, happy 🙂
r/roomba • Roomba that would stand a chance with a Golden Retriever ->I think the Roomba J9+ is the best fit for this scenario. Object avoidance is on par with the best of them, although none are perfect. Note that object avoidance is meant to avoid things that can get robot jammed up or make a worse mess, like cords or pet waste. Larger objects, like bags and chair legs, it will bump into but do no harm.
r/RobotVacuums • Object avoidance without mop ->I believe the J-series all have the same object avoidance, but don't get confused with the "Combo" versions. Those have mops and are much more expensive. The J9+ (non-combo) is currently the only J sold that is vacuum-only. It's currently $500 US, which really isn't that much more than what you can get a used J7+ for, but you'd miss the 2x suction power, the 2x battery life, and the warranty.
r/RobotVacuums • Object avoidance without mop ->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.
r/RobotVacuums • Consumer Reports is way off on the robot industry ->So I love mine saves so Much time and effort. I just make sure kids mess is in 1 room or picked up at night into bins and then just run it. Technically the Roomba j9+ I have avoids items in the ground but still I prefer to clean up the floor before it goes off to vacuum and mop. I do still need to mop weekly or so for a good cleanup but definitely vacuum is done.
r/toddlers • Moms of toddlers, what do you think of robot vacuums? ->Agreed, I had to have my j9+ replaced once because of several issues and the replacement dock they sent me doesn’t even work! The J5 has been great though, these combo robots are not very good IMO
r/roomba • Roomba combo 10 - is it as bad as they say? ->I have the Roomba j9+ and the Braava since before combo robots became mainstream when it was the only real mopping option. Then it stopped working so well (for what it could do). So needed a new combo option for the mopping even though j9+ is suitable for what it does. Had planned on getting rid of it knowing wouldn’t get that much for it really. Then decided to keep it as upstairs only robot where not much mopping to do and I do that myself, rather than dragging combo robot and base upstairs.
r/RobotVacuums • Already have a robot vacuum, would like a combo instead ->The Roborock S8 Pro Ultra is a beast insane suction, rubber brushes that don’t tangle with fur, and it mops too (if you’re into that). For a cheaper but still effective option, the Eufy RoboVac X8 Hybrid gets the job done with dual brushes and strong suction. If you’ve got a heavy shedder, the iRobot Roomba j9+ is pricey but worth itself-emptying, avoids pet messes like a pro, and handles carpets like a champ. Avoid anything with bristle rollers
r/RobotVacuums • Best Robot Vacuum for Pet Hair Now ->irobot roomba j7+ is quiet and has great avoidance system. the next one, j9 is more powerful so it’s louder sometimes.
r/RobotVacuums • recommendations for self emptying + object avoidance and preferably quiet robot? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
