"I run it once a day, and mop a couple times a week. ... In fact, my wet/dry floor vacuum just died so its pulling even more work right now as it's the only real mop I now have, other than a Swiffer."
"My GOD am I glad I did. I had no idea how much I had been missing! ... We have 2 dogs and a cat, and live more rural. That means dirty paws folks, and a lot of them. The mopping and vacuuming has been no short of amazeballs. Not amazing. Amazeballs."
"The current champ of perfectly sparkling clean floors. ... Have 5 dogs tracking in dirt all day? Run this mop and go eat off the floor. That's how clean it is. ... Step aside spinny & vibration mops, this constantly clean roller mop is the champ. ... The mopping ability is light-years ahead of the Curv. ... The continously cleaning of fresh water is where is truly unique. ... You will be delighted and shocked on how amazing this E28 is. Its truly incomparable to any roborock. Get ready to start eating off your floors 😁😉"

"I run the X10 daily on schedules, and it has never been stuck even for once, isnt that amazing? The navigation and obstacle avoidance is truly amazing. It is almost a true set and go experience."
"It also doesn’t bump into stuff, slows down and turns around before running into anything. I am impressed. ... The navigation is night and day between this and J9+, no more bumping or getting lost. ... I think it’s better, it has the front facing camera which looks to be higher resolution, plus the LiDAR does make a huge difference to the speed of navigation, plus it doesn’t bump into furniture or doors anymore."
"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."

"It did a perfect job so far, I only have to empty/fill the water tanks in the station once a week (the robot vacuums the whole flat everyday and mops the flat twice a week)."
"We have four roborock S7’s running in our 5,000 sqft office. ... Bought them since they first came out years ago. ... They run every day. ... Only last year did we replace the battery for all 4. ... Other than that, no issue at all, rock solid, very pleased that we also have them for our homes too."
"What I really love is how little effort it takes—the base cleans and dries the mops on its own, so I barely have to lift a finger."

"But, there is one feature in Dreame that other brands (except Narwhal) don't have! A fur/hair compression in a dust bin. ... It uses air pressure to compress fur or hair in the bin so it would be packed and the robot could vacuum without needing to empty the bin many times."
"even though it can lift its mops pads, it means the mop pads stay dry initially so no carpets can get wet"
"The RGB camera enabled robots can detect cat litter and appropriately increase suction, slow down, and stop the side brush to avoid scattering it."

"It picks up all the cat fur, all the dog fur, all the litter, all the human hair."
"I have one teenager who’s messy and a dog who sheds like it’s her job. It’s been a game changer."
"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."

"It's just very bad performance when it comes to vacuuming. ... This has been the same performance since day 1 with original brush also. ... It seems the suction is not as close to the floor as it should be. ... My budget eufy L60 can pick up this debris with no issue on deeper carpet. ... This is the most basic requirement of any vacuum."
"The bigger issue is that the paths are not as tight and overlapping. ... When I look at the cleaning paths with the MOVA On the tightest setting with the max number of passes (x3) It has nowhere near the coverage of the qrevos and the carpet is not clean. ... The Revos get really tight around legs while the MOVA barely tries to approach. ... Both my Qrevos are much quieter than the p10 ultra and actually leave the carpets looking clean."
"Hair Pickup on carpet is better than the S7 MaxV but still worse than the Neato D7. ... I confirmed this by running the S7 Max V first (with rubber brush), on my upstairs carpeted room - that I purposely haven't vacuumed in a week. S7 Max V barely got anything and had some wrapped around the edges - as it does. ... For me yes but I say that mostly because of the tangle free vacuuming of pet hair and the improved hair pickup on carpets. I was tired of cleaning out the old one and so far with this I have zero tangles. ... The S7 MaxV had the worst hair pickup on carpets, with the stock rubber brush, of all the bots I ever owned. Tangles were minimal but it didn't do well taking hair off the carpets (it did great on the hardwood/tile though). Swapping out the rubber to the bristle brush improved the pickup but increased the tangle problem - it also created a problem with auto-empty for me a few times. ... It mops/vacuums significantly better than my S7 MaxV. Especially on carpets (especially especially pulling dog hair off carpets). ... That being said I LOVE the anti-tangle brush. 3 Months and I haven't had to clean the brush one time. It's literally perfect for me."

"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"
"The j7 got stuck often, maybe 1 out of 4 cleanings it either sucked up a cat toy or jammed itself under something."
"It is dangerous to trust it if you have a risk for pet accidents."

"My dreame l20 ultra clogs with pet hair. ... We have one golden retriever dog and it seems to not go back to the dock enough even on the highest setting to empty."
"the vacuum gets clogged with dog fur immediately and then just rolls the rest around and forms clumps. ... I have one big dog. ... My old Roomba never had a problem with two big dogs (one was the same and the other shed waaay more)."
"The Q5 Max+ was always jammed with what looked like lint/dog hair. It wouldn't get sucked into the base and would just clog the vacuum."

"I contacted technical support, and they refused to help me. ... The mouse is not covered by an international warranty. ... They advised me to travel 7,000 km back to Turkey and contact the seller. ... This is the worst experience ever."
"Dreame support is basically non existent. ... Just do research here on people's experiences here on warranty repairs and replacement. 9/10 times they get a device back in worse condition or device is just kept hostage."
"the replacement dock they sent me doesn’t even work!"

"The issue with those brushes is that it will tangle hair like crazy. ... I have multiple females that shed hair at a crazy rate. ... I would think the brush would get clogged after a day or two. ... Can't deal with manually untangling the brush that often. ... I wish dreame had utilized something similar."

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
r/RobotVacuums • Dreame L50 Ultra Durability ->My dreame l20 ultra works very well. I even find options in homeassistant i don't see in the native app
r/homeassistant • Which robot vacuum is best with HA right now? ->I read this stuff and wonder to myself did I get the only properly functioning robot but then I remember I have 2 and both of them function just fine. L20 Ultra and L10S. Is it just people with no issues say nothing? Are people not doing regular maintenance? I am not doubting anything said here but am genuinely confused as to how there can be so many issues.
r/RobotVacuums • Dreame is a scam ->could also be dreame L20, I have the same dirty water tank.
r/RobotVacuums • I envy all these perfect floors that these robot vacuums so easily clean. Here’s one typical 45-min cleaning session at my place. Hey manufacturers: want a REAL test of your machines? Send em my way. Enough with those pristine reviews. Come to the real world. ->I bought the Dreame L20 Ultra for 600 on Amazon. Best vacuum I've ever had. Also it integrates with Home Assistant very nicely. I can voice control it to clean whichever room I want. Still figuring out how to set parameters with voice or set up buttons that automatically set them to what I want, but the ability IS there.
r/homeassistant • What's the best robot vacuum and mop IYO? Is it really worth its expensive price tag you paid? ->Dreame is always spoken about highly, I have one and it dos an incredible job I have the L20 ultra. Not the best/most expensive but for the money it does great for us.
r/RobotVacuums • Best vacuum and mop robot ->Dreame l20 ultra has been amazing for our home. 2 kids and a dog. It’s gets around and only got stuck 1 or 2 time over the last 3 months. We have been very happy with our unit. Smart and gets to all the rooms.
r/RobotVacuums • Best robot vac for mopping and obstacle avoidance ->I have 2 dreame L20 Ultras, the app and smarts in navigating is just good, it simply works compared to other units I see on here. I literally just set it and have forgotten about it for the week. All I need to do is remember to change the water, which I constantly forget to do it because the unit just does it thing without me needing to intervene.
r/RobotVacuums • Dreame GoVac 508 VS Roborock Qrevo MaxV (Costco) ->I have a dreame l20 ultra. It looks really well, but the vacuum gets clogged with dog fur immediately and then just rolls the rest around and forms clumps. It's still better than vacuuming manually because I can just pick up the clumps. I'm thinking about being in a second vacuum to help with the fur. I have one big dog. My old Roomba never had a problem with two big dogs (one was the same and the other shed waaay more). I'm interested in this thread to see which is best for fur.
r/homeassistant • What is the best robot vacuum currently that's really worth buying? ->What have you found best for carpet? Also cord avoidance? We have a dream L20s ultra and I’m debating putting that in the basement (virtually all carpet) but two teens with all the phone chargers that seem to be thrown around like confetti on new years and buy something fancier for upstairs which is virtually all LVP and some tile. Also— has there ever been a robot carpet cleaner? Also also, do you think the heated mops are worth it?
r/RobotVacuums • I write about robot vacuums for a living. AMA. ->Dreame L20 Ultra or Roborock S8 MaxV Ultra. Both auto-lift mops for carpet, crush it on large homes, and need minimal babysitting 🙌
r/RobotVacuums • Recommendation ->Vacuum Wars is legit. Go Dreame L20 Ultra or Roborock S8 MaxV Ultra. They're great for LVT, rugs, clutter, and low maintenance. Should last 3–5 yrs with basic upkeep.
r/RobotVacuums • Vacuum wars recs good? Looking for best low maintenance combo bot I can get ->I have been using Dreame l20 for about 15 months . So far satisfied . We do use vac after mop a lot and I do think detaching mop for vacuum is nice add on. We did add tricut brush and I think that dies mage a difference especially with hairs
