"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 obstacle avoidance is also very good and I only have the pet in house setting on for pet messes and it recognizes my fake dog poop all the time and drive around it."

"I also have two giant long haired (nonshedding excessively) cats. I shed hair a LOT. Worse than the cats. It works so well."
"It works great with long hair and long haired corgi fur in my home. This is absolutely tangle free in my use and the correct cover can stop hair from going to the sides."
"mopping is BETTER than i do."

"A good robovac is a life changer. Even a $350 basic S8. It is a great place to start. ... I promise you that you will not be disappointed by a basic S8. It will change your life even if it can't fit under every piece of furniture you own. ... My two S8s just finished vacuuming our entire house in about 46 minutes. ... While my floors were being cleaned, I sat comfortably on our patio in the cool shade with a slight breeze and composed my far too long response to you while sipping a diet soda and relaxing. ... I will have to spend about four minutes maintaining my two S8s. This will be my entire contribution to my home floor cleaning effort for today. Four minutes!"
"Like 500$ these robots are currently the steal of the century ... You can get a mova p10 pro ultra (cannot remove its mops), equivalent to the l40/x40 for 500$ after a discount code"
"I got the Q5 Pro for $139. ... costs $450 less than what I paid for the S6 ... it is the best value option out there imo."

"I have 3 parrots so the floor ALWAYS has something on it. Bird poo, food, small chunks of wood, doesn't matter robots got it covered."
"I’ve seen on the camera the poor guy making multiple trips to self empty while in one room but it’s cut the hair buildup tenfold."
"With three they can just make it to a full week for emptying. ... Life changing."

"Mopping is stunning, I mean I’m staring at our floor speechless. ... My floor is cleaner than it’s ever been.."
"Dreame and their MOVA subbrand by far is the best at edge and corner vacuuming and mopping"
"Dreame is currently the best at deploying the side brush and extended mop with the best edge mopping."

"The biggest issue for me is that the moist chunks gum up the vac tray in the dock and I have to clean it regularly. ... It’s the plumbing that empties the dust from the vacuum. The robot scoops up wet barf chunks that get in the dust bin and when the dock empties the dust bin the wet chunks stick to the dock and when they dry it’s like concrete since they mix with cat hair and dust that gets swept up. I have to unscrew the dust bin emptying chute and clean it in the sink and sometimes need a screwdriver to scrape the stuff off."
"the dock was even more of a pain to clean ... the little brush on the dock was disgusting to clean"
"now the dock doesn't dispense water when cleaning mops or washpad, so there's no longer any mop cleaning."

"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."
"The eufy X10 Pro Omni has reduced suction power ... is much worse than the eufy Omni E25 while not being much cheaper. ... That's probably the reason why some people say to stay away from it."
"It does a terrible job with getting close to the wall and collecting debri and dust."

"It would leave rolled up hair everywhere since day one"
"For the L40 ultra, I also had the issue where it had very poor hard floor performance even with the tricut brush. ... Turned out that the roller wasn’t touching the floor so debris would not be picked up and was defective."

"Returning my L40 tomorrow because of recurring mop installation issues. ... Seems pretty common but there’s no fix. ... It’s frustrating."
"I came back today to an error where the L40 couldn’t pick up the mops it had dropped and wanted me to manually put them back on after it cleaned the carpet. ... It has happened a few times now and I had to turn the feature off."
"After just 500 sqm of cleaning, I’ve been waiting for over a month now for it to be returned, and I still don’t know if they’ll fix the mop attachment issue."

"Ecovacs has the worst after sales of any company in any place of the world I have ever experienced. ... The company won’t take responsibility and goi around in circles. ... They wasted more than 6 months after talk to multiple people and site visits and it was escalated till the head of the after sales who I will name clearly: Tanmay Gangani, who is an absolute unprofessional and blatant liar with no sense of responsibility and ethics."
"charging exception faults that they cannot fix"
"Got it replaced and the cost was 8K. ... the replacement cost was again 8K. ... Their service is expensive. Even to just visit and check the issue they charge 1K."
L40 is the best at obstacle avoidance I think The problem is how much do you value mopping because the eufy e28/25 seems to do the best there. And I think all flagships robots will likely switch to their roller style mops in the future because it's just more sanitary to clean the mop as you go. Narwal flow seems like it'll be better the eufy e28/25 when it releases but the price also seems too high That said, e28 seems to perform worse at object avoidance.
r/RobotVacuums • A bit overwhelmed... ->I ordered a white L40 Ultra from Amazon with code DMBFCML40 $359.99. Found on Slickdeals
r/RobotVacuums • Black Friday / Cyber Monday under $380 help ->I recently got a Dreame L40 and really like it. It can leave the mop pads at the dock, which is a really useful feature if you have indoor cats. You can set it to vacuum first, then return to the dock to pick up the mop pads so it's not dragging them all over with bits of litter stuck to the pads.
r/RobotVacuums • Choosing a robovac for a housewarming present. Any suggestions? ->Look for a vac that has an extension arm for the side brush and mop pad so it can reach into corners. I got a Dreame L40 Ultra and it has these features but I've only had it a couple of days.
r/RobotVacuums • Looking for a robovac truly does edge clean. So any recs? ->The Eufy with roller mops (S1, E25, E28) are generally regarded as the best for hard floors. If you're on a budget, the Dreame L40 is the best bang for the buck right now. It comes with a rubber roller that isn't great for hair but you can upgrade the optional tricut roller that cuts the hairs. I bought one on eBay from their official store on sale for Memorial Day for $500 with free shipping. Supposedly you can call their physical store in California for an even better deal and they will ship.
r/RobotVacuums • recommendation for a person w long hair and a dog that sheds like crazy ->Where? Camelcamelcamel has the L40 ultra as the lowest ever being \~499 but otherwise over 1k
r/RobotVacuums • Insane prime day deals for robot vacuums ->I picked it up today at 477, I installed Keepa on firefox and checked, the last time itw as sub 500 was for a few days in May, but generally seems to hover at a much higher price. Either way theyre probably clearing stock for another model release
r/RobotVacuums • Insane prime day deals for robot vacuums ->I had a cheap one years ago, and despite the low price, it was a waste of money. I recently purchased a Dreame L40 and it cost a lot more than I wanted to spend - but it was actually worth every cent. It cleans my floors better than I can myself
r/smarthome • Will I regret buying robovac, just another overpriced toy? ->I got the Dreame L40 Ulta (USA) during Black Friday and I’m thrilled. I’ve got dogs and cats and wayyyyy too much fur and dust (ranch life). I run it daily. Vacuum. Send it to dock then mop a room a day and it’s made a huge difference. No carpet, all cement floors and vinyl sheet.
r/RobotVacuums • Best robovac/mop ->Vslam is pretty outdated i hated how mine just ran into everything, scratching appliances. I upgraded to the dreame L40. the navigation is so much better, but i am returning it and switching to roborock
r/RobotVacuums • Roomba j7 soured me on robot vacuums. Is it time to try again? ->I found the obstacle avoidance on the Qrevo series to be pretty disappointing. Switched to Dreame L40 and have been very happy. They almost never grab a cord.
r/homeassistant • What are the best robot vacuums right now ->Hello Amandainpdx! I’m deciding between: 1) Dreame L40 And 2) 3i P10 Ultra I would go with your recommendation for the Dreame, but it’s not Prime shipping. And I have 2 dogs, and not sure what they will think of it. With the 3i P10 Ultra being Prime with free returns, so you think this makes better sense? Thanks in advance!
r/RobotVacuums • Prime Day last chance- a few hours left to score PD deals. Are you on the fence? Let's cut through it. ->Pleased you are amused. What is the point in telling people bull shit. I've had an L20, L40, X40. The only one with no issues was the L20 and is still going strong. The L40 and X40 were replaced twice. I've had problems with Samsung . . I'm currently running a roborock, useless with obstacle avoidance, excellent on carpet, and a Eufy E28, very good but a very basic app. It isn't just about Dreame it's about giving no bull shit honest opinions
