"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."
"has a mapping feature that allows me to pick which rooms it cleans"

"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."

"I run it 1-3 times and day, I’ve had it for 4 hours. ... Still works great"

"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."

"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"
"But it is constrained by its app. ... But I think others apps allow much more customization with scheduling that make them more hands free."

"made me realize how shitty the Shark was. ... primarily it cleans way better"
"the long hair is too much and it clogs up the roller and we have to clear it before it can run again."

"The only real nemesis has been shoelaces. We have to remember to tuck in the laces in our entryway, or he will try to eat them and stop running."
"a ton of minor things that make it feel polished, like the robot will announce on its own device speaker what's happening, like why it got stuck or why it's returning to a dock."
"Sometimes it gets stuck, either physically on an object"
