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

"Everything stays clean (two dogs and a dog door, hardwood flooring)"
"Dreame/Mova have exceptional object avoidance combined with excellent cleaning on carpets and hard floors."
"My X40 picks up everything on the carpet and even leaves it decently combed"

"I love that it ’s plumbed in!"
"I have an X40 Master and would not want to go back to filling and emptying water tanks. ... I have a lot of floor area so depending on how much water I set my earlier model robot to use, it could run out before the clean is finished. The X40 Master solves that problem completely."
"it even re-mopped when it sensed the water coming off the pads was excessively dirty--a feature I scoffed at initially, but was pleasantly surprised by."

"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."
"It is the only vacuum (robot or otherwise) that the fur does not get stuck in the brushes! ... I have had it for 6 months and have not had to cut fur from the brushes yet."
"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 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 L10 is quite weak on corners/wall edges (and needless to say the 40 is the best)."

"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."
"failed to dock itself almost 80% of the time. ... Its right wheel couldn’t get on the ramp, so it didn’t even get near the contacts."

"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."
"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"
"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."

"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."

"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"
