"significantly worse object avoidance than than the Dreame x40 and L40 ... The best feature of the L40/X40/p10 pro ultra is that they have class leading object avoidance so you don't have to pick up your cat's toys or prep your house every time you want to run the robot meaning you can run it on a daily schedule which will keep your house cleaner. ... I run my X40s daily and they never get stuck on cables, cat toys and other random junk that ends up on the floor."
"The X40 is so far ahead in the object avoidance realm that it's not even a contest. ... I have my Dreame X40 running at midnight every day and never have to worry about it getting stuck on something or caught on something because it's object avoidance works so well, even in the dark and on all surfaces. ... It stays clear of cat toys, cords, socks, paper towels and all sorts of random household junk. ... the fact that I can run the Dreame daily will keep my house cleaner."
"the object avoidance on the dreame is far better than the eufy. That'll really help with toys and other loose objects that you're sure to have with kids."

"I think its hands down the best all around option right now, especially once you hook it up to the water line and drain, i run it daily in our house and we got rid of our cleaning help because of it."
"Dreame/Mova have exceptional object avoidance combined with excellent cleaning on carpets and hard floors."
"I’ve got two dogs that shed like crazy, so I’ve got it running every day to vacuum"

"I can basically always trust my X40 to finish a midnight cleaning session in the dark and wake up to find it sitting in its dock and have clean floors in the morning."

"Dreame and their MOVA subbrand by far is the best at edge and corner vacuuming and mopping"
"For corner cleaning, Dreame is the most aggressive in terms of its algorithm."
"The extendable mop pad feature is a must-have. ... It was actually able to mop slightly under appliances, and where there was baseboard or a hard edge, the mop ran all the way up against it."

"The vacuuming is really good at picking up all dog hair (4 dogs, 2 of which are huskies)."
"Twin rollers are a bit nicer if you’ve got pets that shed a ton ... Twin rollers are genuinely helpful for pets. They grab more hair and are less prone to tangles compared to the single roller, so that’s the biggest dog-owner benefit."
"Got the dream a few weeks ago. It's a game changer. I had a Neato and a few iRobots over the years. With those units, I spent more time pulling out dog hair and untangling rollers than actually using the product."

"The x40 that I bought was refurbished and had wonky navigation so I sent it back"
"I just spent an hour today re-calibrating where all are the rooms in my apartment are because it suddenly shifted my house 30 degrees and couldn't reach any room. like, it would start driving into the wall instead of going to the room I asked it to clean. ... aside from that the map from time to time will get distorted and I'll need to manually make adjustments so it more or less aligns with where the actual rooms are."
"it keeps going in circles with no rhyme or reason."

"It is dangerous to trust it if you have a risk for pet accidents."
"because it thinks my rubber anti-fatigue kitchen mats are a cliff so it gets stuck on the mats (something my cheaper robot vacuums with Cliff sensors never had issues with) ... a common rubber kitchen mat that other robot vacuums have no issues with should be easy for a $1000+ robot. ... it's Cliff sensors are over sensitive and prevent my X40 from properly cleaning my kitchen with it getting up onto my anti-fatigue rubber rubber mats and then getting stuck on them since it thinks the edges are a cliff."
"I had to replace roller twice because object detection was lacking and roller tore."

"Dreame's support was so bad that I didn't even bother getting a new one, just wanted a refund. ... their support made me jump through massive hoops, spanning nearly 3 weeks, in order to get, what was initially just a replacement... but it was such a nightmare I ended to just telling them I wanted a refund, I didn't want the replacement anymore."
"careful with Dreame’s refurbished on ebay, they don’t really check if the robots are working so it’s up to your luck, once you’re beyond the 30 days return window they’ll stop responding and you’re basically on your own. ... I really vouched for their refurbished units but they totally disappointed me, replaced my unit that had a small problem with one completely broken (doesn’t turn on and all scuffed up) and fully ghosted me after previously responding within a few hours, likely because my return window closed. ... I’m currently going through multiple channels to get a resolution but have been without my vacuum for a week so far. Just destroying their reliability if u ask me. Buy new."
"Dreame customer service sucks. ... I have feeling no 1 over there understand basic English or the translation app they use is joke. ... Never buying that crap again. This was my 2nd X40 purchase for my parents."

"I’m actually hoping the new Dreams firmware that allows the side brush on carpet rolls out soon. If it doesn’t, I think I’ll be disappointed because of have several area rugs that are close to walls that will not clean well without it. ... Really hoping firmware is released in the US soon for the X40 to allow the side brush on carpet. I’ll probably return it if it doesn’t because I think it I’ll reduce its effectiveness on my kitchen floors."
"I have an X40, which I wouldn’t recommend for carpet owners even with the tricut brush."
"the x40 ultra doesn't spin the side brush on carpet which makes it a no go if you have edge to edge carpets."

"the x40 ultra was broken (wheel doesnt move)"
"it won’t slow down, so expect loud noises ... I’m not sure how good that constant impact is long term. ... My 40x’s just push through and hope for the best"
Quick answer: Yes Explanation: Whilst spinning mops were more of a "it maintains a clean floor reasonably well" deal. The rollers are a "I can clean the entire house properly without you doing anything" deal. Some will argue they are worse with dried on stains, which I guess is true, but reality is, with my Aqua 10 has rarely seen a stain which it did not remove on the first pass. Anything from like dirty shoe footprints to oil from cooking it picked up in one pass. (If that botters you, you can just quickly spray the dirty stains with some water before it passes over it, so it is a bit soaked I guess, but in my experience the X40 also had problems with such stains). Now lastly maintenance. And honestly, this is the main issue, right now we are using first gen rollers, which the manufacturers didn't really take time to consider how the products themselves would be cleaned. I found that having it vacuum, and then vacuum and mop was the best way to prevent any debris entering the mopping system, so no need to clean it every week, rather every 2 weeks maybe.
r/RobotVacuums • Are roller mops the only sensible choice now? ->If you have hardwood flooring, get Eufy S1 Pro (best mopping device. No other vacuum is remotely close) If you have some carpets, get Dreame x40 Ultra (edge cleaning and mopping)
r/RobotVacuums • Best robot vaccum and mop ->I own x40 and s1 pro Eufy has excellent support. Dreame are ok it seems sometimes they don't understand what we are trying to say. I can be wrong, but it feels like they use Google Translate to reply to emails. They have better overall product 🙂 S1 Pro is best if you don't have carpets.
r/RobotVacuums • Dreame x40 is currently the best vacuum out there. ->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.
r/RobotVacuums • Dreame is a scam ->That would make it non returnable sadly. Weird how it get scratches so easily though because my X40 Ultra has zero scratches after months.
r/Dreame_Tech • L40s Pro Ultra is absolute disaster on Carpet. ->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!
r/RobotVacuums • Best Robot Vacuum for Pet Hair Now ->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.
r/RobotVacuums • Best Robot Vacuum for Pet Hair Now ->I have a Dreame X40 Pro Ultra. It purports to have this feature, but I've never tested it since I have a cat that goes in its litter box.
r/askSingapore • Best robot vacuum for poop avoidance ->We love this thing otherwise. It works great. Got it for about $1600 during a sale. It's still expensive of course, but for our house totally worth it. Never vacuum and mop by hand anymore!
r/askSingapore • Best robot vacuum for poop avoidance ->One more thing... On pretty much any of these units, you can designate certain areas to avoid completely. If the dog accidents are always near the pads, you could just designate that whole area off-limits to the vac.
r/askSingapore • Best robot vacuum for poop avoidance ->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.
r/RobotVacuums • Which one of these 3? ->That makes sense. I ordered an X40 Ultra because it was cheaper than L40, but I was deciding between it and the RR Qrevo Slim. I can’t decide how important object avoidance is since we usually clean the area up daily even though we have 4 kids. I’m actually hoping the new Dreams firmware that allows the side brush on carpet rolls out soon. If it doesn’t, I think I’ll be disappointed because of have several area rugs that are close to walls that will not clean well without it.
r/RobotVacuums • Bit the bullet, cancelled the Dreame L40 order and bought the Qrevo Slim ->Thanks! Really hoping firmware is released in the US soon for the X40 to allow the side brush on carpet. I’ll probably return it if it doesn’t because I think it I’ll reduce its effectiveness on my kitchen floors.
r/RobotVacuums • Bit the bullet, cancelled the Dreame L40 order and bought the Qrevo Slim ->If it makes you feel better L40 and X40 no better
r/Dreame_Tech • This is how bad the L20 is at the vacuuming carpets / rugs. ->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
r/RobotVacuums • Dreame L50 Ultra Durability ->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.
r/RobotVacuums • I write about robot vacuums for a living. AMA. ->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.
r/RobotVacuums • Help me choose: Narwal Freo Z Ultra vs. Roborock S8 MaxV vs. Dreame X40 Ultra. ->I did. I thought the x50 was a nice upgrade, but the x40 was ok.
r/RobotVacuums • Big Deal Day Recommendations by House Needs ->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...
r/Roborock • Saros 10R 24 Hour Review ->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)
