"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."
"I’ve got 3 kids home all day and it does great with tons of food, hair etc."
"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 only robot vacuum that didn’t clog or burn out was the self emptying shark one ... it’s been going three years strong."
"Get one that has the auto empty dock. I empty mine every couple of days that way."

"The big thing for me is the app and the map. Once it learns the house you can send it to just individual rooms to clean which is a lifesaver with small kids as rarely are all the floors clean at once. ... I send the robot and it’s amazing."
"I love the mapping function because I can keep it out of certain areas depending on how good I was at preparing the house."
"Sharks clean in a stripe or grid pattern whereas roomba is a seemingly random pattern that drives me nuts. ... also has an option for what they call matrix clean but it’s basically a grid, it’ll do stripes all one way then perpendicular to really get everything."

"We have a German shedder in the house and our shark has been amazing (AI ultra). ... Virtually no issues with hair stuck in the brushes ... always amazed how much is picked up after a session"
"I ’m a long-haired person with a Shark robot vacuum with the self-cleaning roll. ... Occasionally hair does accumulate on the axel of the roll, so I clean that out maybe once every six months. ... Until other vacuum manufacturers can do better than Shark’s self-cleaning brush roll, I haven’t considered other vacuum cleaner brands."
"I enjoy Shark because of the self cleaning brush roll"

"the long hair is too much and it clogs up the roller and we have to clear it before it can run again."
"If it doesn't get run at least once a day, the roller brush will get clogged."
"gets clogged sometimes because of Belgium malinois fine hair."

"it ’s randomly stopped talking to the app (I’ve troubleshooted it as much as I can short of calling support), so now it’s lost half its functionality."
"Occasionally with an app update your robot will act like it ’s lost and doesn’t know the map and you have to remap the house which is annoying"

"I miss being able to have the robot clean specific rooms in a specific order like my iRobot did. ... The shark is very random on the room order it cleans. ... Sometimes it starts with the living room. Sometimes it starts with the dining room depending on the day"
