Dreame - X40 Ultra

Eufy has excellent customer service. They sent me replacement parts for S1 Pro and took a follow-up 2 times to make sure all was working fine. Dreame customer service sucks. I have feeling no 1 over there understand basic English or the translation app they use is joke. I was able to dispute the situation with my credit card and got a refund for $1800. Never buying that crap again. This was my 2nd X40 purchase for my parents.

That would make it non returnable sadly. Weird how it get scratches so easily though because my X40 Ultra has zero scratches after months.

Just got the [Dreame X40 Ultra ](https://www.reddit.com/user/Accurate_Shine5695/comments/1jhg9u6/best_highend_robot_vacuums_of_2025_a_quick/)and it’s a game changer for pet hair! Super strong suction, picks up all the fur without any issues. Plus, the vacuum AND mop combo is perfect for keeping everything spotless. The self-cleaning and self-emptying features are a big bonus, less hassle for me. Highly recommend if you’ve got pets!

The Dreame X40 Ultra uses advanced LiDAR navigation and AI-powered object recognition to effectively detect and avoid obstacles, including small objects and potential hazards. Its upgraded sensors make it more reliable in handling unexpected messes compared to older models like the Roborock S7. While no RoboVac is 100% foolproof, the X40's smarter navigation significantly reduces the chances of mishaps like running through pet waste.

I‘ve got the x40 and i‘m super happy so far. We have both hard floor and rugs and it cleans them really well.

If it makes you feel better L40 and X40 no better

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

Hmm . . X40 and x50 I tried both poor. L50 best one I've had

I am often surprised, and offended at how much difference there is in premium robots (which is what I tend to test, rather than budget or midrange). You should expect, if you pay that much, for a robot to work. This problem is much worse in lawnbots, but there is no condition under which I would purchase a Roomba or Eufy on purpose. Doesn't matter what model. I'm most impressed by Roborock, Dreame and Ecovacs. That said, each model is different. For instance, I thought the X40 was just fine. Didn't blow me out of the water. But I think the X50 is quite good, although it still has some navigation issues. I haven't tested the Monsga line, sorry.

this is easy! Freo Z uses too much water, you have to refill it ALL THE TIME. hard pass. Dreame x40 is.. good... but not great. The S8 MaxV Ultra is truly great.

I did. I thought the x50 was a nice upgrade, but the x40 was ok.

Damn I really wish to have a full review from you on the X40, it's kind of my favorite (bought two, first on December, the second one today, and thank god no need of support just yet) and I always love hearing reviews that compare it to other robot vacuums, because in my eyes and in my experience - it's perfect, yet I hear so many complaints about it that I just keep on praying to never need to use the warranty... 

I really appreciate the thorough response man, truly. I hope you never need customer service 💪🏽 and it seems to be a global thing with Dreame, as the complaints go from country to country as I hear them... I just really hope to never need them. And tbh, in my country they didn't bring the Saros 10R, only the 10, so I wasn't so keen in getting it with the vibrating moppad.. Also the retractable Lidar that has expiry times-of-use threw me off a little.. So I ended up considering either another X40 or Ecovacs x8 for the roller-mop, but ecovacs' last release here got destroyed in reviews, and so I just decided to go with what I know (and love, for now lol) 

Recently got a Dreame X40 Ultra, it’s pretty nice. Can’t think of anything else I’d need from a vacuum. I just change the water containers; liquid detergent usage is pretty minimal so it’ll last months. Love that the mops are detachable magnetic pads instead of the velcro type and it automatically washes & dries them at the base station

Can only speak from my own experience, but I’ve had the X40 since December last year and had no issues with it- apart from a dodgy software update that was fixed in a week. It cleans a large 2 bedroom flat with a short haired dog most days and the communal hallway twice a week all in its stride. The hallway has a set of stairs at the end and never had any problems with its fall avoidance. I would say to use distilled water if like me you live in a hard water area.
