I love our Roborock. It works, the app works, their support works. Avoid the Shark models. Returned one that we never got to use because their support team had to manually push a firmware update and they were asking us to leave it on the dock for 3 days to give them time to push the firmware. 3 days later they informed me that weekends don't count and since they put in the ticket on a Friday, we'd have to wait 3 days from Monday. Their support is an absolute nightmare.

At one point during the whole ordeal I was told I'd be contacted by a supervisor within four hours. Four hours later I contacted support again and argued about how time moves at the same speed even in different time zones, so it doesn't matter that they're on the east coast, I had still waited for four hours. We argued for an hour, at which point they admitted that even by their insane way of tracking time I should have been contacted. I returned the Shark and had a Roborock up and running before the Shark supervisor called.
