"The combo 10 max (almost the same obstacle avoidance as all other modern/j-series iRobot models) initially scored in vacuum war's top ten for obstacle avoidance. ... It's also the only brand that guarantees avoidance of pet poo."
"For true obstacle avoidance(like where it can ultra low objects like clothes or cables on the ground)your best bet would be a Roomba J7 ... There is very few true robot vacuums with good obstacle avoidance"
"roomba J-series with obstacle detection will never run over even the thinnest cable. even if it is a small part of the cable."

"super easy to get long hair out of the rollers/wheels/whatever. ... Wife went through chemo and it was a test for the robot...both survived!"
"The side brush picked up a HUGE hairball while mapping my apartment—I cut that off. ... On the initial vacuum, the brushes picked up a bunch more hair—I pulled them out and got all that off. ... Now I have the Roomba on a 3x/week schedule and hair isn’t a problem at all."
"Roomba's pickup performance is miles above all other robots (unless you go with extremely expensive ones such as Dyson 360° VisNav, or discontinued ones like Electrolux Pure i9.2) so if that's factor #1, you really should keep them in consideration :)"

"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"

"Comes with a base station that it blows the content into. ... Super low maintenance that way."
"Even my Roomba j7 will periodically empty with no manual intervention."
"The auto-empty cycle is also longer than other robots, about double that of the J7."

"my roomba j5+ is the only one that is reliable and working at the moment"
"I have 270 hours on it so far with no issues ... I rate the j5+ highly."
"iRobot are still providing parts for 12+ year old bots. ... It's clearly designed for repairability."

"The j7 got stuck often, maybe 1 out of 4 cleanings it either sucked up a cat toy or jammed itself under something."
"My roomba j7 does always get stuck on hairs from my big dog… and it’s so annoying…"
"every so often it gets stuck on something ... if you have a messy floor that could be a bigger problem (I keep mine very tidy)"

"It ’s super loud ... Noise at least on hardwood is easily double the qrevo"
"Plus they were obnoxiously loud."
"pretty high noise from the vacuum"

"it takes forever to clean. ... it takes at least 2x the amount of time to clean the house."
"the cleaning takes about 4 hours total. ~1 hr for single pass vacuum"
"doesn ’t clean as well ... It ’s less thorough and less efficient."

"The little bin in the robot itself is tiny and constantly needs emptying"
"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"
