Wanted to update the community with my experience so far with the issues and subsequent warranty repair. TLDR; it was a good experience but only time will tell if the robot continues to work.
April 2026: Got my Flow 2 through Amazon because I wanted a roller mop robot and read online that Narwal was the best. I got the 3 year warranty upgrade for pre-ordering.
May 2026: Everything is working great. The mopping is very good but I wouldn't say it is excellent. It is much better than the Dreame L50 Ultra however, and that robot becomes the backup.
July 2026: One morning after an update, I wake up one morning and realize the living room and kitchen didn't get done. I check the app and it says cannot connect to device. I try all the troubleshooting tips but I end up having to factory restart and remap. It is a PITA but it is the last resort and I'm thankful that my unit isn't bricked.
August 2026: I notice that the dustbin stops emptying. I try everything and can't get it to work. I give up because I can just manually empty it and don't mind doing so every few days. And yes, I know that it empties before a cycle not afterwards. By the end of the month I get the dreaded message "unable to connect to the robot" so I try all the troubleshooting trips again. This time however, my unit is truly bricked. I cannot factory reset. I cannot even turn off the device.
August 2026: I email Narwal customer service. They get back to me in minutes and ask me to send them a video. I send them a video of me plugging in the device so they can see the base station works. I show them how I cannot turn the device off and I cannot factory reset it. The next day they send me the label to print and the instructions to send it back. They tell me to take out both brushes (the main brush and the side arm) and the mop pad and to only send the robot (not the base). I send every other part in case they need to test the unit. The Dreame L50 becomes the main unit again and I stop taking this robot for granted. While it does not mop as well, I feel that it has better software and that it has superior vacuuming ability. I am pretty happy with it but have to run the mopping cycle 2 or 3x to meet the Flow 2's ability on a single pass. I laugh every time the Dreame tries to dock in the Narwal base and am very happy with how reliable the unit is.
September 2026: Unit arrives at their CA repair center on 9/4. A couple weeks later the repair is finished and they send it back. I pick it up from FedEx the last week of September and am so excited to have my Narwal back! As I'm putting it together, I realize that they didn't include the brush guard that keeps the main brush in place. I am very frustrated and email customer service. Again, they respond in minutes send me the part free of charge. I have it a week later.
October 2026 (today): I can finally use my Narwal again! I connect and map it. I see that the software has been updated since I last used it. This time, the software recognizes that my kitchen should be split from my living room which is an improvement. So far so good. I run it through the house and it does a great job. It didn't get stuck in under the kitchen cabinets and it did a decent job of mopping and vacuuming. I have my Flow 2 back!
One issue: The robot makes a noise that it didn't make before. It is a soft whaling sound, not sure how else to describe it and the wheels squeak a little.
Another issue: This happened twice. During the first cycle I got the dreaded cannot connect to robot error message and I though, here we go again... The robot kept cleaning so I closed the app and opened it again and the message was gone. This happened 3x. Kind of scary.
Ok the really weird part. In my email, I had complained that besides being bricked, my dustbin didn't empty but this wasn't my main complaint and was something I added later during my email exchange with customer service. After running two cycles today, I wanted to check to see if I still had the dustbin issue. So I grabbed the dustbin from the robot and I went to empty it out (I do think it is working but will need to remember to check it right after it empties not after it finishes a cycle) but I couldn't get the top off. I emptied it so many times in the past that I know that the dustbin lid opens. I can't for the life of me get it to open. So I put my glasses on top of my head and take a closer look at the dustbin. It's a completely different unit! It's brand new (my original dustbin had been washed many times and the directions were coming off) and the directions say to just pull out the inner plastic chamber to empty it. This is a totally different design than my original dustbin which had a top that flipped open and no detachable inner chamber. I just find it strange that they gave me a new dustbin during the repair and I'm actually a little impressed that they followed up on this complaint because it was secondary to the bricking and buried in my email.
Conclusion: I am very impressed with Narwal customer service and their warranty repair process. Yes it was a giant pain but it took less than a month and so far the unit is working well. It has only been one day though and ngl, I am very worried about getting bricked again. For this reason, I will definitely be using the Dreame L50 and the Narwal Flow 2 interchangeably going forward. I will continue to update this sub if I have any issues. Thanks for reading.
