"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."

"Dreame x40 Ultra vs 2 German Shepards. ... Life changing. ... Haven’t needed the vacuum cleaner since we got it."
"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"

"Hot water mop wash + hot air dry = way less stink, better hygiene. ... Dreame’s just smarter and cleaner long-term."
"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."
"It really does work in my experience and it’s genuinely never been stinky, negating the need for me to put bleach in it and shaking it around."

"it manages to gobble all my hip-length hair up without getting any tangles at all."
"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."
"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."

"The L10 is quite weak on corners/wall edges (and needless to say the 40 is the best)."

"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."

"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."
"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."

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