"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."
"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."

"Love how the mops extend and swing under low hanging places like my fridge and I could see an obvious difference in cleanliness as soon as I opened my fridge door to check how it did."
"Dreame uses this method. This method relies on the hair first getting tangled and then the hair strands will enter a groove where there is a hidden knife to cut the hair, sending it into the dust box with the vacuum fan ’s help. Dreame’s brush is also engineered for the hidden knife to move like a razor after 23 revolutions. In my experience, it’s been stellar at long hair and my long haired corgi’s fur. ... they have a new brush cover now to cover the non-brush compartment of the TriCut brush and it works great at preventing any hair from getting to the sides."
"Dreame x40 Ultra vs 2 German Shepards. ... Life changing. ... Haven’t needed the vacuum cleaner since we got it."

"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."
"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."
"Only the Dreame with detachable mop pads and iRobot have this figured out from my experience. ... The mop pads can be set to auto remove themselves at the dock prior to vacuuming carpet."

"Each vacuum can clean each of my floors on max suction ~750sqft without having to stop and charge and each finishes in around 1-1.5 hours."
"The Battery life is great and was able to vac and mop the whole house with about 40% remaining."
"love it. ... 41418 sqft, 14670 min run time, 303 cycles. ... Best $0 i ever spent lol."

"I've got a Dreame X40 specifically because it's supported by Valetudo. (Local only cloud replacement so you can use most of the features of the robot without needing any cloud services."
"Dreams X40 is the best if you want local control."
"software and navigations is light years ahead"

"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."
"It is dangerous to trust it if you have a risk for pet accidents."

"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."
"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."
"Dreame’s own customer service is only good if you speak Mandarin Chinese."

"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."
"the x40 ultra doesn't spin the side brush on carpet which makes it a no go if you have edge to edge carpets."
"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."

"I spilled some coke and started spot cleaning. I don't understand why I need to exit CleanGenious, but fine. I defined the area and hit the clean button. I got a weird question from the app about maps and I said don't change anything. Could hear it work in the other room instead, for a very long time. And looking at the app I saw it has created a completely new very jagged strange map 45 degrees tilted. I aborted the clean. In the app I hit the Map editing button, and saw "Temporary map" that is the weird one created. I hit the button to switch and I can see my old map there. Hitting Apply it asks me to Confirm I want to remove the temporary map and switch to the old one. I can see "Loading data..." but it just takes me back to the weird one. I can't get my map back! My problem with the X40 is that it can't be trusted. Great hardware, feels solid and well engineered, but I really hope the software gets fixed."
"obstacle avoidance is a software thing now you have it perfect in next update it’s a mess."

"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"
"My 2000pa wyze robot vacuum has much better hard floor pickup performance than my 12000pa Dreame x40."
