"significantly worse object avoidance than than the Dreame x40 and L40 ... The best feature of the L40/X40/p10 pro ultra is that they have class leading object avoidance so you don't have to pick up your cat's toys or prep your house every time you want to run the robot meaning you can run it on a daily schedule which will keep your house cleaner. ... I run my X40s daily and they never get stuck on cables, cat toys and other random junk that ends up on the floor."
"The obstacle avoidance is also very good and I only have the pet in house setting on for pet messes and it recognizes my fake dog poop all the time and drive around it."
"The unit was an upgrade from a Roomba S9. That unit did a good job of vacuuming but was very prone to having problems with obstacles. For example, it would launch itself up onto the circular rod -like bases of several of my chairs and become stuck there. They Roborock 10R correctly recognized all of the bases as something to avoid. Some of them get labeled as chair bases and others simply as wires. It has avoided every obstacle."

"I’ve seen on the camera the poor guy making multiple trips to self empty while in one room but it’s cut the hair buildup tenfold."
"With three they can just make it to a full week for emptying. ... Life changing."
"the hair cutting feature on the dock means i havent had to get in there and chop out all the cat hair or long hair from 2x long haired humans."

"I absolutely do not regret buying the robot vacuum. ... My room is a lot cleaner and dust-free now, and I can tell just by wiping my floor with a wet toilet paper and seeing barely anything picked up. ... I've been getting allergens a ton less, most of which not even in my room. ... All this for the commitment of a weekly emptying is miles more convenient than vacuuming traditionally, as opposed to making a few taps on my phone. ... looking back it was definitely worth the investment."
"My cat has very bad mite allergies, and this vacuum is a must have for us for keeping the floors clean of all dust, dander, and dirt."
"The second floor of my house is all carpeted, and I used to clean with a Dyson V8, but since I got the E28, I haven't vacuumed myself."

"The roborock I have kicked and smashed with my foot so many times out of anger when it doesn't collaborate, and still he rocks 4-5 yrs later and no broken parts"
"I've used it daily for at least 10 years now, probably closer to 15 and apart from the fact you need to clean it periodically, it's still works like brand new."
"One huge leg up for a Shark over Roomba is that the brush roller is similar to a vacuum (e.g. hard plastic), whereas the roomba is a plastic roller with a rubber cover that is DESTROYED by dog fur and you have to frequently replace."

"The fan that circulates the air is so ridiculous it sounds like an airplane is idling inside my house, and it literally changes the air pressure in my kitchen and hurts my ears"
"I don't even want to be home when my roomba is running."
"Plus they were obnoxiously loud."

"half the time it isnt running because of a clog in the vaccuum bin or base station. ... The bin is usually easy to fix, but this last time it was the tube that goes to the bag (another expense i didnt have with the shark) and that required disassembly."
"it still can’t make its way through our home without getting stuck. On nothing. ... It’s just been pretty hands on and very frustrating."
"The running times to sweep our main floor have gone from a few hours to now over 6 hours."

"Sick and tired of the Q5+ sucking up my toddlers socks"

"the one that worked great started doing something similar -- runs about one minute then stops and starts beeping."

"The issue is with both the inlet to the bin inside the robot and the door of that bin to the base station bag that is too smal."

"flow’s cannot be removed by an average user ... You literally need to disassemble the robot to access the dirty water tank."

"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."
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.......
jjmoreta 0.6I bought MO on a Amazon Prime Days sale - refurbished. Roomba i or j7 or similar, I forget. 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. The tower holds a bag where the cup can be emptied, especially if it fills up halfway through the run. I do not ever want to manually have to do this with a robot vacuum. I \*hate\* dust cups even on stick vacuums. He is not the sole link between dirty floors and clean for me. I still have to vacuum with my full-size vacuum, but I have to vacuum less (once a month if no one comes over) and I can keep the main vacuum upstairs now. I love how he can be scheduled, MWF at 10am. I have joked at times he is the most reliable guy in my life. He is happiest on an open floor plan with steady borders (furniture stays in one place and there are no random piles of objects or clothes or toys appearing) and no changes in floor level (my old house had a sunken 2nd living room I had to tell him didn't exist or he'd get stuck). Cords and anything with dangling strings are the worst enemy. And he will suck up little legos or earrings without you knowing that he did. But his existence does help me with keeping the floor cleaner, for him. He can go under our new IKEA sofa which worries me, but at the same time I just picked up a backpack and a purse a few moments ago so he won't be impeded on his next run. I'm letting him map the place and I may block off areas again as needed. He's not always a perfect perpetual self-maintaining tool. He's having a problem in the new house with getting seated on his base with the charging ports properly so he charges every time. I'll have to troubleshoot that. In the old house he'd get stuck on sunken areas or wedge under furniture frequently and if not rescued promptly, he runs out of juice. I would usually have to send the kids to hunt him down and rescue him. 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. Noise also helps the cats know he's coming and they just give him a wide berth. Oh and if you get one, buy the bulk packs of non-branded replacement parts off Amazon - way cheaper and just as good. The base takes vacuum bags and he has a rubber beater "brush", sweeper side brushes and a filter that all wear out over time (couple times a year). I keep an eye on them and the app keeps track of the expected life of each. He also needs googly eyes - I have been remiss in this. But he's a part of my household now. I am chronically ill so there have been times in the past few years that he was the ONLY vacuuming that got done and he helped us keep a much cleaner house.
AdCharming612 0.2I have the j7 and I have taken it apart more than once to clean it and I'm not super happy with it. I got it at Costco so it might go back before they go belly up. I'll try it again a few more days but I didn't even have it plugged in for 6 months... because we had renovations going on in the house. It's Black Friday week but I prefer to buy from Costco because they do have such a good return policy.
Affectionate_One4208 0.2I have a roomba j7 and I have two dogs, it's great with dog hair
Blissphu 0.2Single 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.
bradatlarge 0.2I got a J7 and a robo rock q5+ max or whatever it’s called. The roomba was $700 the Roborock was half or less. I think the Roborock is better
CosmoKramerRiley 0.2We 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.
CourageHistorical100 0.2Combos from iRobot aren’t that great, to be honest. The i5 as a vacuum isn’t bad at all. It’s the lower mid level but no less cleans decent. J5 and j7 are great mid to middle upper levels. I have limited experience with a combo and I wasn’t a fan. The vacuuming aspect of things is great.
curiouscanadian2022 0.2Same have the j7. I will look into roborock. It looks like a lot of people in this comments are saying the same thing
Curmudgeon7777 0.2That 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.
