"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."
"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."
"identified obstacles well. ... It never got stuck. ... Never sucked up a sock, pen or tissue. ... the AI was awesome."

"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."
"The vacuuming is really good at picking up all dog hair (4 dogs, 2 of which are huskies)."
"Dreame/Mova have exceptional object avoidance combined with excellent cleaning on carpets and hard floors."

"Hot water mop wash + hot air dry = way less stink, better hygiene. ... Dreame’s just smarter and cleaner long-term."
"The tray on the x40 is spotless and i remove it once a month to clean the filter in it."
"Dreame X40 Ultra with a water pump so I don't need to replace the water every day"

"Dreame on the other hand actually extends in any case that the robot thinks it cannot reach normally which results in much better edge and corner cleaning performance."
"The Dreame also does a better job cleaning edges and corners due a better extending brush design and extension algorithm."
"it uses it's side brunch effectively to get into corners."

"stopped doing edges ... each week it got worse at navigation, essentially only doing half rooms ... stopped sweeping and mopping anywhere it transitioned from rug to floor ... It would leave 2 ft circumference around every rug unswept which was horrible near dog doors and the rug in front of them (main reason I got vacuum!) ... But was not willing to deal with it stopping sweeping the entire floor. ... It was glitching out around edges"
"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."

"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."
"Yes. It does not spin on Carpet which is the same as Dreame. Dreame however 9 months later implemented the ability to spin the brush on carpet if you wanted to via the app. ... Dreame, meanwhile, it took nearly a year to enable side brush spinning on carpets, and Roborock now faces pressure to implement similar improvements."
"side brush not spinning on carpets ... Also the lack of side brush on carpet is a bit annoying. ... They have had almost a year to implement the brush on carpet feature which the L40 for some reason has now but the X40 still doesn't have."

"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."
"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."
"Support was slow as fuck too. ... They would response once per day to my email even if I replied instantly. ... They created a shipping label, but I said fuick that I'd rather return it to Amazon and buy this roborock vacuum instead of waiting around for the robot to get to them, they look at it for weeks, then send it back to me saying they didn't find a problem."

"The tricut brush which you can purchase and install does a excellent job preventing hair wrap but I have found it is significantly less effective on hard floors. ... It seems to do fine in most cases but I did notice the robot fails to pick up medium sized debris like cat treats. ... Yesterday I did some drywall patching and had some drywall chunks and pieces for the robot to pickup and the tricut brush just pushed the debris around and accumulated it in the brush guard failing to push it into the dustbin. ... It would appear to pick it up but when the robot turned around all the debris would be left at the spot where the robot turned."
"It would leave rolled up hair everywhere since day one"
"I have a Xiaomi robot made by dreame that uses the same dustbin as the X40 ultra. This is how much fur it gets every morning. https://preview.redd.it/9edw1042217f1.jpeg?width=1600&format=pjpg&auto=webp&s=923a84c91ae678589d54fe338015c0071d0835ed ... I run my robot twice a day because it ’ll choke on my dog’s fur if it ran once a day."
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 ->A couple comments. I have the X40 pro Ultra and can say that the lifting/lowering lidar is a big deal to me. It can now get under all the furniture in my house to vac and mop. The dual roller design of the x40 pro ultra is different and is the same as the top Roborock - it is the best I have had for carpets and much better than the single brush too. I noticed that you had all rubber brushes which are not as good on carpet as bristle. You can get a rubber /bristle combo for the vac ( if it wasn't already included) which will improve carpet cleaning performance significantly.
r/RobotVacuums • Honest Dreame X50 Ultra (Pro) review - tl;dr included ->Same here. Really happy for each of the features.
r/Dreame_Tech • My experience with Dreame L40 Ultra ->I have the very same issue in the kitchen. I had a X40 pro and it was already not the best. But the aqua roller is worse! I tried ten days and really gave it a chance. But I really don’t see one single reason for keeping it. Very disappointing
r/RobotVacuums • Dreame Acqua 10, expensive product or alpha test? There are big problems here. ->I tried the aqua 10 roller and I was surprised by the results. In a bad way. My guess is that there is not enough pressure on the floor with this system. The robot is not heavy enough and the result is really less than average. As comparison I also have the X40 from Dreame and it is way more efficient. I sent the aqua 10 back.
r/RobotVacuums • Are roller mops the only sensible choice now? ->I have this one as well, but the version without the self emptying deck. I'm always scared of bugs climbing in there and nesting before I get to empty it. This being said, I love it, and it's not even my first Dreame: I've never been able to find a better quality/price deal.
r/CleaningTips • Self emptying robot vacuums for homes with many pets? ->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 ->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 ->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 ->I purchased a refurbished Dreame X40 Ultra from eBay. It’s been super solid. I just got the tricut brush to see if I can get a little bit better performance on carpet with our shedding dogs.
r/homeassistant • What are The Best Robot Vacuums Recommendations Today for Busy Folks? ->I’ve got a Dreame x40, and my sister in law has a Dreame l30. We’re both super happy with them.
r/RobotVacuums • Need help choosing between 3 robo vac/mops. ->I have a Dreame X40 ultra. I live in a 1 bedroom apartment with 2 sheddy dogs and it does an ok job on carpet and a pretty good job on hardwood. I bought it refurbished on Amazon for around $700
r/smarthome • What is the Best Robot Vacuum that Homeowners absolutely love and recommend? ->Roborock saros 10r top of our list Eufy E25 2nd this is already at BF pricing according to eufy Dreame/mova same company and had x40 returned it Narwal not seeing the fantastic reviews from individuals and the onboard bin might be too small for 2000sqft home with 2 shepherds even with daily vac JMHO
r/RobotVacuums • What robot vac is everybody looking to buy Black Friday? ->Hated dog hair the bin is small and it had no option to go back any faster to the base to empty so it would just push piles of hair around till the algorithm told it to go back and empty but it would never retouch the pile it left. they kept telling me to select a function that was not in my menu. so they took it back took months but its gone. and service is 1 email a day after they answer the phone on first ring so one problem will take a week to sort out and they dont want to call you back, just email there comes in around 2 am yours goes back at around 9am and then wait
r/RobotVacuums • What robot vac is everybody looking to buy Black Friday? ->I just shipped out my x40 they offered me a x50 refirb but i said no. I'm done with dreame and mova is just another division of them. Looking a roborock revo curvx, narwel flow or the ecovac deebot x11 but thier t50 pro max is coming highly recommended with dog hair. still looking
r/RobotVacuums • Looking for new robot vacuum ->too many issues and never solved the first problem and then the second started
r/RobotVacuums • Looking for new robot vacuum ->If you have the gift card, I dont have one but dont want the e25, Im looking at the mova z60, I just dont want the experience we had with the dreame x40 pushing dog hair around and never really picking it up. we have the bot run everyday a little over half the house twice a week and the main are daily with 2 german shedders well you get it
r/RobotVacuums • Looking for some real experiences with roller mop robots ->Sounds like its the one, my x40 never got an update to make it empty more often
r/RobotVacuums • Looking for some real experiences with roller mop robots ->I have the S1 Pro. It would do a much better job then the X40 regarding mopping and have navigation that's at least as good. But the X40 as a massive edge in corner cleaning and vacuuming on carpet.
