Got mine yesterday. So far so good!
I thought it would have mapped out the whole house by now, but it’s still cleaning till the battery runs down then it recharges and keeps on going. Some areas have been gone over multiple times and it still hasn’t ever stopped cleaning unless it was to recharge. I’m thinking it’s still doing the discovery thing. It does pick up a ton of dust though. We have all laminate and tile with a couple of rugs and it’s surprising how much it finds.
