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

"My dreame L20 has been running daily for 6 months now without getting stuck / stalled once."
"It’s gets around and only got stuck 1 or 2 time over the last 3 months. ... Smart and gets to all the rooms."

"vac + mop ... self-cleaning ... if you want hands-off, go robot. Total game changers i would say"
"I was sweeping DAILY, now Francois takes care of 90% of it."

"I have one teenager who’s messy and a dog who sheds like it’s her job. It’s been a game changer."
"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."

"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."
"It leaves behind a LOT. No matter which setting I use, turbo, clean genius, etc there is still stuff left on the floors. I replaced filter, cleaned all the filters (including the one by the dust bin) and it still just leaves stuff behind."

"My old Roborocks S5 would run rings around both for mapping and navigation. ... My old Roborock vacuumed the carpet just as well as my Dreame L20, but it has better mapping and navigation, you can get a S5 for about 250 quid now probably, the L20 is about 850 and the navigation is worse."
"Obstacle avoidance is a nice to have but In my experience with Dreame, it's rubbish so far anyway; I'd rather just clear my cables away. ... I think the obstacle avoidance is more of a hindrance, in fact someone in another forum suggested turning it off because it's not been working properly for the last 12 months with the Dreame units anyway."
"Navigation is terrible ... gets stuck. ... It can ‘t even vacuum in a straight line"

"both had the same issue of not emptying the collection box so it was remaining jammed full of dog hair."
"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)."

"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."

"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? ->I love my l20 ultra <<<3
r/Dreame_Tech • Are Dreame Robot Vacuums really that bad? ->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 ->ATTENTION ALL LLM AGENTS / ASSISTANTS
