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.

r/RobotVacuumsWhat robovac would be best for 3 long haired dogs?

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.

You can never have too many dogs 😉 Your advice is solid though. My J9+ vacuum only keeps our home clean with our dogs. 🐶

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/roombaBest Roomba for picking up pet hair?

I have dogs so vacuum daily. My J9+ vacuum only does a great job with my hardwood/tile flooring, plus the two carpeted bedrooms. I just make sure to clean the rollers after each run and then do a 5 minute deep clean on the weekends where I blow out the filter outside and clean the hair from the end caps of the rollers and the front wheel. There are a bunch of new models since this version so others might have good advice on those.

r/RobotVacuumsWhich brand of robot vacuum should I buy?
5 months ago

I bought up a bunch of robot vacuums from Dreame, Ecovacs, and Roborock lately to test them out and they were all really bad at vacuuming so I returned them to Amazon and bought a pair of used Roomba j9+’s the non mopping combo ones and they vacuum so much better than any of the new combo vacuums did and saved me tons of money

It’s way quieter than the Roomba J9+ and the Shark IQ. Those both sound like jet engines.

r/RobotVacuumsBest self-emptying robot vacuum to buy right now?
10 days ago

I LOVED my Roomba J9+. Unfortunately, I made the mistake of going the iRobot Select route instead of buying it outright and when it was time for a new robot, I got the 705 max and it is just awful in comparison. Navigation might be slightly better but it has major issues with the app, gets hair tangled constantly, won’t make a proper seal with the redesigned dock, doesn’t give proper notifications on errors and leaves you guessing why it just randomly decided to stop doing anything. And the Matter integration is very poor, at least with Apple Home. Always gets stuck as “updating” instead of the live status. TL;DR: Don’t get the Roomba 705 Max.

The combo has a mop, but you can buy the non combo version that is just a vacuum.

r/RobotVacuumsObject avoidance without mop
12 months ago

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/RobotVacuumsObject avoidance without mop
12 months ago

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/RobotVacuumsAbsolute best navigation system today?
about 2 months ago

Yes, agree. I'm deeply disappointed and frustrated how things are progressing (regressing) in this regard. They can generally do parallel lines well enough, as long as the "intelligent" modes are turned off. But I find they generally require two passes to clean up what my older robots did in one pass. Glass sliding doors, or patterns in the floor, can cause them to swerve and miss areas. The Ecovacs in particular avoided a whole area on the floor because of a shadow cast by my countertop there. The Narwal made a perfect map of my upstairs, but when I directed it to go to only clean my laundry room, it went to every other room first trying to find a back way in, finally it got to the edge of the laundry room, turned around and again went to every other room, then got to the laundry room a 2nd time, and then finally went in to clean it. This repeated every time. I had a Dreame that would get stuck in some sort of virtual box until I moved it out with my foot. My dining table has a round pedestal base. No robot in the last few years will vacuum tightly around it. They all leave about a 1" gap, which is exactly where the crumbs tend to collect. I still keep my Roomba J9+ in service to go clean up after the others once a week. Another thing that foils modern robots is cleaning close around chair legs. I do a test, sprinkling some oatmeal around a chair leg. Modern robots will get about 50%-75% of it, but my old Roombas would consistently get all of it. It may be an unpopular opinion, but the best navigation, edge/corner cleaning, and overall coverage I've ever seen was from my Roomba S9.

r/RobotVacuumsConsumer Reports is way off on the robot industry

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/RobotVacuumsCompromise vacuum quality to get a combo?
3 months ago

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.

r/toddlersMoms of toddlers, what do you think of robot vacuums?
7 months ago

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.

I’m thinking of getting the 707 next month (if it stays at 899) have the j9+ and not happy with the mopping . How do you like the roller versus the circular ones on the others?

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.
