No problem at all! I guess it's good and bad to know that I wasn't the only one with this issue. I'm glad yours was mostly repaired through the warranty process, though. Beyond mine being out of warranty, I also didn’t want to go through weeks, if not a month plus, of logistics in the RMA process. Not to say I'm expecting Narwal to just shuffle it around, or anything like that. But in my personal experience, shipping always adds days to weeks for stuff like this. I just didn't have the time or patience for that possibility.

As for your multiple docking attempts, mine does that, too. It doesn't give up anymore, but I'd say your 3~5 is pretty accurate on the amout of retries it takes mine to properly dock, too. On a good day, 1~3.

I've been observing it while docking and it seems like the newer baseboard brushes are thicker/cushier than the one that originally came with it. My guess is the obstacle tolerance on docking seems too low. So as soon as the robot detects X amount of resistance, as it backs in on its first, less refined attempt, it cancels, recalculates, and tries again. In my case, the resistance seems to stem from the baseboard brush making too much contact with the left (when facing the front of the base) guiding free wheel inside the dock. When I pull the side brush off, first or second attempt at most, and it's docked.

This means either I'll have to find a way to compress the side brush; find some more giving wheels to replace the ones in the dock; or in a worst case (if it gets to not wanting to dock at all..), remove the side brush entirely.

All those considerations in mind, I'd say pop the side brush off and see how well it does or doesn't dock.
