"my J7s with the wall sensors perfectly ride along the edge barely touching them. But close enough for the edge sweeper to do its job."
"I think my J7 dragged a charging cord once in 3yrs."
"to avoid pet messes ... It was pretty darn great for about a year."

"I had my first for >10 years before I upgraded and no complaints with the one I have"
"My fav part is the robustness, if it encounters a huge problem, the only parts that break are those (and then rarely) are those meant to swap out."
"I only had to buy a new one after 6 years because it went through dog vomit under my bed, and I stupidly sprayed it with water in an attempt to clean and fried the mother board. ... But my new one is on year 2 or 3 now and it's great!"

"literally NOTHING robot works like an iRobot that I’ve seen so far esp the j7 and the 988 those are the strongest in their class"
"I have hip length hair, and it gathers it no problem. ... I also have 4 dogs inside and used to have a cat."
"it does a good job of keeping the fur contained."

"it's the navigation that is problematic (hard hitting walls/furniture, poor coverage, and getting lost)"
"J series especially has dumb pathing issues."
"J7 gets stuck at the top of a "cliff" (stairs) from time to time, and the J5 never did."

"The amount of time it spends vacuuming everyday is about 2 hours and I still need to break out the clunky corded vacuum. ... doesn't clean well enough to justify its price"
"the j7 was excessively slow when the spaces were filled with furniture, like the living room"
"the cleaning takes about 4 hours total. ~1 hr for single pass vacuum"

"And I got the tower with him which is the ONLY way I will ever own one of these robots again, after a period of time where I had a dust cup error and had to find a dusty/grimy robot, flip him over, empty the cup and then reseat it without errors. ... I do not ever want to manually have to do this with a robot vacuum. ... I *hate* dust cups even on stick vacuums."
"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."

"I don’t like that I have to keep lights on ... iRobot heavily relies on cameras for navigation and doesn’t work well in the dark because of that"
"Heads up on Roombas: they require enough ambient light for their cameras to work. They're not into LiDAR navigation, which would allow them to do their job at night with all the lights off."

"My Roomba is loud and annoying ... listening to the vacuum for 2 hours basically do nothing has gotten extremely annoying."
"pretty high noise from the vacuum"
"He's also not the quietest, but I don't necessarily mind it unless I have a meeting scheduled at the same time (I work from home), but I can just pause him with the app on my phone at any time."
BlackWolf-359 1.02 dogs as well and the last robot (dreame) could not handle the hair, but the Older J7 roomba no mop did a great job. the Narwal flow and the Ecovacs are at the top of the list right now. Next week and in November are possible launches for newer vac/mops so we will see. cant say much on the wifi issue
I know I came from the J7 worked well and then the contract ended, not interested in paying for something beyond its price and it was starting to have issues, so we retired it and went with d and 7 months later it's not what they said it would be and IRo better get their game together fast or the once leader in floor robots will be gone and all that will be left is.......
johnb300m 1.0At the risk of being downvoted to the 7th level of Hell. I have been using two refurbed Roomba J7s on my main floor and basement. They’ve worked great so far. Very few errors or issues.
Idk, my last LiDAR robot scratched the shit out of all my baseboards where my J7s with the wall sensors perfectly ride along the edge barely touching them. But close enough for the edge sweeper to do its job.
Roomba j7, it does the kitchen every day, and the rest of the house every 2 days. Works great, even though it’s VSlam. Sees and skips obstacles, pet toys and messes. 🤞
Idk. I’ve seen a couple videos of the 705 and I’m shocked at how inferior its obstacle detection and avoidance is compared to both of my J7s. I think my J7 dragged a charging cord once in 3yrs. But the 705s on YouTube ran over cords, kids toys etc. so far the 705 can still avoid dog poop. Thank goodness.
I’ll just chime in that the two Roomba J7s I got refurbed, have been great. A little glitchy at times. But I’ve not heard of a single robot that is never glitchy. Initial mapping took forever but the VSlam navigation and obstacle detection and avoidance have been awesome. I’m coming from an old WYZE LiDAR robot so the bar was low. There are tons of parts for the J series so I’m happy about longevity. Hopefully IRobot survives so the app servers stay on….
My old Roomba j7 sees and avoids cables every single time. 🤷🏻
Nope. I’m still rocking out two Roomba J7s I got refurbed. I know it’s popular to hate on iRobot, but they’ve worked well for me so far. Good navigation, good cleaning, lots of replacement parts. It’s even skipped a surprise pet mess. That was nice.
Affectionate_One4208 0.3I have a roomba j7 and I have two dogs, it's great with dog hair
Blissphu 0.3Single one. I had a J7 before, dual rollers. For now, I didn’t notice a drop in quality for vacuuming with a single roller. I ran a full house cleaning run yesterday and we we’re impressed with the results.
CosmoKramerRiley 0.3We have 4 cats and currently use a Roomba J7. It's programmed to vacuum once a day, and it does a good job of keeping the fur contained. We do have an upright vacuum that we also use, but the Roomba does a good job for us.
Curmudgeon7777 0.3That is crazy. Even my Roomba j7 will periodically empty with no manual intervention.
I just bought the Roborock QX Revo from Costco. I’m moving my Roomba j7 to the basement. If the Roborock doesn’t work out I will just return it.
I have a 900 series and a j7. I don’t really have an issue with either one. They rarely get stuck and complete jobs regularly. However I recently bought a Roborock and it is definitely better. The app is much more advanced and lidar seems to be more efficient and accurate.
double-click 0.3Do you really want to deal with mop water? When floors need mopping just get out a traditional mop and roller bucket. You don’t need a 2000 dollar vacuum. Most of the hardware is the same. Software quality is not. A roomba j7 will navigate around all chairs and do what you need a robot vacuum to do.
EFCF 0.3DO NOT BUY, RETURN THIS PIECE OF CRAP. I had a J7 that I bought for $700 (not on costco) less than 2 years ago, and it just stopped working about 2 months ago, needing a new "head cleaning unit" for around $90... that was out of stock. Roomba is a garbage company that puts no effort into developing smarter, better machines. I said F it and bought the RoboRock on Costco so I would have the consumer protection of costco if any problems. It is amazing, empties its own dust bin, and mops the floor for us.

emzim 0.3I got a refurbished roomba j7 on Amazon for $200 and it’s been great! Don’t be afraid of refurb! My refurbished Dyson stick vac from Amazon is still going strong after 10 years of use, only needed a couple battery changes.
fakegoose1 0.3I recently got a roborock, I was using a Roomba j7 previously The roomba had no lidar and only relied on camera. The Roborock is miles better at navigating than my roomba. The roomba would slam into everything while the Roborock will get close but not actually touch or just lightly brush against walls and furniture.
