So, i have the z60 standalone, i'm trying to fix water drops with different configuration types. But the mapper and the vacumm works well. I don't know why but compared with my old Dreame L20 Ultra, seem have less built quality, that's why i'm thinking of try luck with Aqua10.

Pleased you are amused. What is the point in telling people bull shit. I've had an L20, L40, X40. The only one with no issues was the L20 and is still going strong. The L40 and X40 were replaced twice. I've had problems with Samsung . . I'm currently running a roborock, useless with obstacle avoidance, excellent on carpet, and a Eufy E28, very good but a very basic app. It isn't just about Dreame it's about giving no bull shit honest opinions

I read this stuff and wonder to myself did I get the only properly functioning robot but then I remember I have 2 and both of them function just fine. L20 Ultra and L10S. Is it just people with no issues say nothing? Are people not doing regular maintenance? I am not doubting anything said here but am genuinely confused as to how there can be so many issues.

Dreame is always spoken about highly, I have one and it dos an incredible job I have the L20 ultra. Not the best/most expensive but for the money it does great for us.

Dreame l20 ultra has been amazing for our home. 2 kids and a dog. It’s gets around and only got stuck 1 or 2 time over the last 3 months. We have been very happy with our unit. Smart and gets to all the rooms.

I have 2 dreame L20 Ultras, the app and smarts in navigating is just good, it simply works compared to other units I see on here. I literally just set it and have forgotten about it for the week. All I need to do is remember to change the water, which I constantly forget to do it because the unit just does it thing without me needing to intervene.

I have a dreame l20 ultra. It looks really well, but the vacuum gets clogged with dog fur immediately and then just rolls the rest around and forms clumps. It's still better than vacuuming manually because I can just pick up the clumps. I'm thinking about being in a second vacuum to help with the fur. I have one big dog. My old Roomba never had a problem with two big dogs (one was the same and the other shed waaay more). I'm interested in this thread to see which is best for fur.
