"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."
"Even on hardfloors, I found the QRevo slim still was not as reliable and consistent at avoiding obstacles as my Dreame X40."

"Dreame/Mova have exceptional object avoidance combined with excellent cleaning on carpets and hard floors."
"No competition between them dreams x40 is so superior it’s not even funny. ... And with the auto detergent it makes more sense for it to wash the mops that way it actually smells good! ... You’re flat out wrong about the “solution injection” being superior to washing the mop with solution. ... I have had both models and roborock did not properly wash my floors. ... The dreams I can literally smell the difference and see it. ... The water gets mixed with the cleaning solution directly onto the mop pad and it goes back to wash every 216 sqft it’s superior. ... I know because I actually can compare the two"

"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."
"I definitely do not have a floor drain. Just added it to my drain. ... It’s really not. I uses a 3/8 water tee which I got at Home Depot that you typically use to plumb an ice machine for the water inlet. Then for the exit they make adapters that will get it to your sewer tap T also at Home Depot. I think all in all it cost me less than $20. The only thing I had to order was a 3:8 to 1:4 inch adapter for the Compression line on the dirty water. You could get a plumber to do this for you, but they’re gonna charge an arm and leg. It took me all of 20 minutes once I had the right parts."

"excellent hair tangle resistance since you can run the tricut brush. ... I have 2x Dreame x40s and they have the same brush system as the l40 and I have one running the tricut and one without it. Both have been excellent with resisting hair wrap with the tricut having zero hair tangled on it and the regular brush having a small amount on the ends."
"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."
"In my experience, it ’s been stellar at long hair and my long haired corgi’s fur."

"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."

"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."

"I had to replace roller twice because object detection was lacking and roller tore."
"I have gotten two messages asking me to rescue the robot because it sucked up something it shouldn’t have. ... it had swallowed a small toy the size of a Lego."

"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."
"it couldn't hoover close enough to the walls ... the horizontal spinning thing does nothing when everything is carpet ... there was always a foot along the walls where it wouldnt hoover"

"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 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."
"Bro all of these companies do ... Same with roborock. Customer service is even worse so I’m used to it."

"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"
"It sucks on cords and small parts."
