"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."
"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."

"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."
"Dreame/Mova have exceptional object avoidance combined with excellent cleaning on carpets and hard floors."
"Everything stays clean (two dogs and a dog door, hardwood flooring)"

"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."

"Never vacuum and mop by hand anymore!"

"Dreame and their MOVA subbrand by far is the best at edge and corner vacuuming and mopping"
"For corner cleaning, Dreame is the most aggressive in terms of its algorithm."
"I just bought the Dreame X40 Ultra and it cleans the edges and corners floorless."

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

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

"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."
