"I was sweeping DAILY, now Francois takes care of 90% of it."
"My dreame L20 has been running daily for 6 months now without getting stuck / stalled once."
"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."

"it does great with a long haired GS, a VERY long haired husky/mal mix, a long haired cat, a short haired cat, and a long haired woman in the house."
"I have an XL Breed dog (Great Dane- mastiff mix) and during shedding season sheds about 2 chihuahuas worth of hair everyday. And without the vacuum I would cry everyday."
"I have 2 cats (1 long hair, one short), and long haired German shepherd and a husky/malamute mix (FLUFFY!!!). I also have long hair. ... I was having to sweep the house DAILY. Now I only do it when I give "Francois" a break for a couple of days."

"And my floors have never been cleaner"
"I also live in rainy Portland and having it mop everyday really really helps with dirty paws etc."
"I liked the mopping from the dreame l20 ultra. I felt the eufy left streaks in the floor upon comparison."

"vac + mop ... self-cleaning ... if you want hands-off, go robot. Total game changers i would say"
"I don't have any problems with my robot, it vacuums and mops every day and empties itself without problems with hair clogging or anything like that."

"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."

"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)."
"slowly having issues emptying the dust bin. ... Taken up emptying it manually once a cycle."

"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."
"suctions isn’t good ... it constantly misses spots ... it also takes 3.5 hours to vacuum the same area my roborock does in 1 hour but cleans up less. ... I did a test and ran the dreame for 5 days straight on regular vacuum and then right after ran the roborock when the RR was done it had a full bin. Ran the RR two days later and it picked up a bunch then ran the dream and it was almost empty. It’s just crazy how bad the performance is."

"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."

"the robot has been having trouble getting back into the dock when running overnight, which has led to a lot of aborted cleaning sessions."
"Navigation is terrible ... gets stuck. ... It can ‘t even vacuum in a straight line"
"I fixed the issue myself but the l20 to me is just crappy. It works sometimes, sometimes not."

"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 dreame support is actually trash so not looking for that company tbh. ... dreame, just based upon my experience has some trash customer service lol ... yeah, I bought mine from Amazon. A year later I was having issues, I frequently get bounced between the US/Chinese team and it's been torture lol"
"I will be claiming warranty via all state as soon as the first year period is over because I don't trust sending it back to dreame at all."
Alfonso2k 1.0So, i have the z60 standalone, i'm trying to fix water drops with different configuration types. But the mapper and the vacumm works well. I don't know why but compared with my old Dreame L20 Ultra, seem have less built quality, that's why i'm thinking of try luck with Aqua10.
allah191 1.0Pleased 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
AnduriII 1.0My dreame l20 ultra works very well. I even find options in homeassistant i don't see in the native app
atomicnick86 1.0I 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.
ayodio 1.0could also be dreame L20, I have the same dirty water tank.
beastnbs 1.0Dreame 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.
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.
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.
bigreddittimejim 1.0I 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.
brought-to-you-byt 1.0What 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?
brycemonang1221 1.0Dreame L20 Ultra or Roborock S8 MaxV Ultra. Both auto-lift mops for carpet, crush it on large homes, and need minimal babysitting 🙌
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.
Bulky-Wrangler-418 1.0I 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
