"I have one teenager who’s messy and a dog who sheds like it’s her job. It’s been a game changer."
"We have 3 cats (one long haired), a very messy toddler and dark dark wood floors all throughout our house. It was impossible to keep clean before this. I never mopped because it was a pain in the ass. Now, we run this thing once or twice a day and they are spotless when it's done!"
"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 was skeptical of the mopping but after running it the first few times and the dirty water coming out like thick chocolate milk, I was pleasantly surprised that after running it every night (or maybe every 2) the dirty water is now much more clear. ... It’s clearly doing a great job at maintaining the state of the floors."
"And my floors have never been cleaner"
"Tell that to my shiny kitchen floors (using the Dreame L20) ... L20 here, my kitchen floor is spotless and shiny"

"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 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."

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

"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."
"Dreame has pretty terrible support so I'd steer away from them"
"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"

"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."
"the robot has been having trouble getting back into the dock when running overnight, which has led to a lot of aborted cleaning sessions."

"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."
