DREAME L40 Ultra Robot Vacuum Self Emptying, 11,000Pa Suction Robot Vacuum and Mop Combo with Auto Cleaning Dock, 149℉ Mop Washing, SideBrush Extendable, Solution Auto Refill, Voice Control

I’m really impressed with this vacuum—especially for the price. I got it during the Prime Day sale for $474, and at that price point, the value is hard to beat. The navigation and object avoidance are solid. Not perfect, but definitely good enough. I have a long-haired dog that sheds like crazy, and this vacuum leaves my hard floors spotless. It also does a pretty good job on rugs, picking up most of the fur. While it doesn’t get everything, I’ve gone from vacuuming daily to only needing to do it every few weeks. The mopping feature is another highlight. I live alone with my dog, so my floors aren’t too dirty, but it’s done such a good job maintaining them that I haven’t had to mop since I got it. The auto-cleaning of the mop pads is also a nice bonus and works really well. It’s important to have realistic expectations with these machines. Robot vacuum technology has come a long way in the last decade, but it’s still not perfect. Navigation and object avoidance can occasionally be a little wonky—but that’s true for every robot vacuum on the market right now, even the high-end models. I think a lot of the 1-star reviews come from people expecting a flawless, zero-maintenance experience, which just isn’t realistic at this stage. We’re not quite at the point where these are fully hands-off or completely autonomous. There's also a lot of debate about roller mops vs. spinning mop pads. I’ve tested this against higher-end options like the Ecovacs T80 Omni and the Eufy E28, and honestly, roller mops feel overhyped. Unless you’re constantly tracking in mud or spilling liquids, you probably won’t notice much difference in cleaning performance. For normal daily maintenance, this spin mop design is more than enough. The app is also user-friendly, setup was quick, and the vacuum is surprisingly quiet—both when cleaning and when auto-emptying. Overall, this robot vacuum offers flagship-level features at a fraction of the cost. I’ve tested premium models over $1,000, and while they might be slightly better in certain areas, the improvements are marginal and don’t justify the massive price difference. With how fast robot vacuum tech is evolving, it’s hard to justify spending top dollar for something that could feel outdated in just a couple of years—especially when you can get something like the L40 Ultra for under $600 that performs just as well.

A month in and I will never go back to our other life. I have 2 Labrador retrievers and live in the woods (no lawn). We have a new home build, so there is still sand everywhere that the dogs, and us, are endlessly tracking inside. Our living space is about 1,000 sq ft with cement floors and wool and natural fiber area rugs. I have a very high standard of cleanliness which I am always balancing with my love for my dogs. Previous life: I was running an older robot vacuum daily, my husband was using the cordless vacuum daily to clean sand and dog hair and I was also vacuuming rugs and hand mopping the floors as necessary. (Probably not often enough) Research: I did a lot research before choosing this model. Pet hair. We have so much… every where. We also still building our house and there is sand and grit and sawdust… every where. I watched endless videos and read reviews on vacuum wars, wire cutter, consumer reports, etc. Originally, I was prepared to spend between $700-$1,200. Why this model?: I narrowed in on Dreame because or the reviews on the effectiveness of pet hair pickup and I did not find any complaints on pet hair not being cleared from the vacuum when it self empties, which was a chronic problem with my older unit. The app functionality had really good reviews, but the thing that really sold me is that it takes photos of your pets. This is only slightly silly, but is seriously what sold me. It tells me that this company knows that a good vacuum and pets are a package deal. I was looking at the L50 but when I started comparing the 40 to the 50, I didn’t see that the newer upgrade had additional features that met my priorities. I decided to spend half as much and went with the L40. What I love: my floors look and feel so clean. I can now walk barefoot across my floors and don’t feel sand. We don’t vacuum daily and I haven’t pulled out my mop since we started using this unit. This is an extra 15 minutes that I get in my life every day. This is now 15 minutes a day that we spend doing yoga because the floors are clean and we can just lay on them without having to vacuum. The maintenance on this unit is easy. In our smaller house (vacuuming and mopping about 740 sq ft daily), I have been adding water and emptying the waster water about every 4-5 days. The unit came with a small bottle of cleaner that filled about half of the reservoir and there is still about 1/2 of that left. The dust collection bag, even with all the dog hair, has not needed to be changed yet. I’ve rinsed out the base (mop head cleaning area) twice. This equates to 5-10 minutes of my time a week for floors that are dramatically cleaner than when we were vacuuming and mopping ourselves. Functionality: The LiDAR mapping is amazing. I’ve run two maps and each one took about 5 minutes. The mapping is very accurate. I did take the time to go through the maps and add furniture and no-go areas, which takes a little time. The object avoidance, so far, has been outstanding. Things are always moving around (dog toys, shoes, chairs, etc.) and I have not had any issues with the unit “getting aggressive” with new obstacles like dog toys or chair bases. It looked like it was going to get hung up on a chair bases once but we gave it a minute and it figured out how to get itself off. The programming for this company seems really good. Very “smart”. It mostly takes care of itself and is very hands-off. It does its job very well and does not need much from me, which is exactly what I wanted. The unit seems to get fully cleared when it empties at the base. This was my biggest issue with my old unit. With so much dog hair, the old unit would over fill and not be able to clear itself out. I would have to either empty it manually or run it more often just to make sure it didn’t pick up more pet hair than it could manage. Other observations/ comments: Yes, it does make noise. It is a vacuum. When it goes from a hard floor surface to a rug the suction increases and the unit makes more noise. It’s still substantially more quiet than a regular vacuum, but it is not so quiet that I would have it cleaning in a room where I’m trying to have a conversation or watch a movie. The object identification is good but not perfect. However, I can tell that it is learning. During the first few runs it identified a shaggy pet toy lost under the bed as a pet. It also identified a loose strand on a rug as pet feces. Over the past few weeks, it has gotten better at identifying the objects in my house and I haven’t gotten any incorrect notifications. It did get lost once behind the couch. I currently have it programmed to vacuum and mop on the same runs. However, I’ve noticed that the mop pads or base of the unit are carrying some pet hair onto the rugs and leaving a swipe of fur where it enters the rug. I will reprogram it to run separate vacuum and mopping sessions, which should fix this issue. (Again, we have a lot of pet hair in our house) I was sold on this unit for the pet recognition feature and the go-find-my-pets-and-take-their-photo-when-I’m-not-home function. It was a novelty that I was excited about. A month in and I’ve used it twice. Now, it is just so novel and wonderful having clean and beautiful floors. I love it.

I started buying robot vacuums back when Romba S9 was the best of the best. While I loved my S9 for raw power it lacked in many other areas I had to move on. Since then, I have had mostly Roborock vacuums. I have owned the S6, S7, and S8 and while I stayed with them mostly for the dual rollers, it seems like overnight robot vacuum evolved, and now they were moping and raising mopping pads with a camera to locate pets and all kinds of bells and whistles side mopping and on and on. I tried the Dreame X30 and while it was a great vacuum it did not seem to have the same raw power as the Roborock Q Master. The Roborock Q Master sucks at object avoidance. No matter what I did or what settings I selected it would not avoid anything. I know no robot vacuum is perfect but the Q Master is listed as being smart and has a camera in theory should help it avoid cords and socks and dogs, but it does not. I picked up the L40 Dreame on sale and have been in love since. It has the raw power like the Q Master but is way smarter. I was so tired of looking around before I ran my vacuum I would clean to clean. The L40 is so much better not only does it run like a dream but I have not had it once get stuck or get something stuck in its roller. It vacuumed under my couch and then in the app at got a notification that I might have a missing item under there, it even took a picture of it so I could decide if it was worth going after. And for the 1st time besides my Romba S9, the vacuum will come back when it is full and empty itself and keep going. I have a Beagle and she shads like crazy if I skip a day of vacuuming other vacuums would get full but keep vacuuming even though they were no longer picking anything up. The mopping is also top notch and not only does it push one mop pad out to the side but it will also wiggle to get even closer. After mopping it will clean and let you know if the water was dirty enough to mop again and then go do it. The only problem is it only does this with genius clean not customized. Also, the side brush no longer spins on the carpet by default. You have to do some trickery to get it to spin on the carpet. Which is stupid to me, I looked around and they saw this is because it's not really needed on carpet and keeps the motor from burning out. I do not agree. I would give it 5 stars but Amazon delivered it to me damaged, and will not replace the item they just want me to return it for a refund. The problem I got it on sale close to Prime Day and it is no longer on sale. So, if I returned it, I would have to pay more to buy it again. If it was a small amount like 25 bucks, I could see that, but it’s like 350. The policy does say I can get an item replaced within 30 days but they are not budging. Everything works besides the cleaning solution injection. So, if you are thinking about buying it, I would say pull the trigger. If you can buy it from someone other Than Amazon that’s even better. Since they will punish you if you happen to find a deal on their site. Update**** While I could not get Amazon to do the right thing and replace the item without me returning it. Dreame support has stepped in and has been nothing but pleasant to work with. I wanna be clear the 5 stars are for Dreame and the L40. Their customer support and their vacuum have been a dream to work with it. I can not recommend them enough. If you are on the fence about buying a robot vacuum from Dreame, I would say pull the trigger. The vacuum is top-of-the-line filled with the best tech. Customer support has been fast to reply and very easy to work with. Until the X50 comes out I am staying with the L40. *********Update********* Still one of the best robot vacumes you can buy hands down and I would buy it again if the X50 was not out :) (I would love to review the X50 Dreame if you are listing) and it seems to be improving itself like it is learning, hear me out. I have two small dogs one that is afraid of its own shadow and another one who could care less about the vacuum. When I 1st got it I was cautious around both both dogs taking what seems like 1000 of pictures of them, even if they were not in the frame all the way. It would slow down if they walked in front of it, it would give them both a wide birth as if it was unsure as to how the dogs would react. Fast forward to today and I no longer get out of 100 pics of them in the app. The vacuum knows that it can get right up next to my dog who does not care and clean around her. But it knows to slow down when the other dog is laying in the middle of the floor because it knows he will get scared and move at the last minute. I swear iuts almost like it is learning and thinking.

The world of these robotic vacuums is horribly confusing. Maybe even on purpose. The mid-tier robots (such as this Dreame L40 Ultra) is littered with so many options, and the prices vary so wildly, it is nearly impossible to feel like you've gotten a reasonable deal. This particular robot was variously priced from $800 to $400 over the space of just a couple of months. When I got it, which was outside of a Prime-Day sale, it was about $480. I watched dozens and dozens of hours of comparison and performance videos and real-world tests, as well as asking AI and making my own chart of features vs price. I landed on this mode for my house. (Look up "Just a Dad" on YT for his reviews). If I were doing this again, I'd probably opt for something with a bit higher suction power than 11k Pa. But 11k does fine. The app is just OK, but is probably on par with the others. Object recognition and avoidance is pretty good but it will not avoid some wires/cables or floor mats. It doesn't always detect carpet really well. What I like is the mapping/sensing/avoidance capability, the mopping, and heated mop washing and drying. I've almost never had it get lost or stuck somewhere unless it got tangled up in a cable... in that case, if you have a problematic area, you just tell the app to avoid that area as a no-go zone. These units work best if they run every day or two. Don't expect a single run to be like a cleaning service. And it won't get under/around everything -- this is for daily use and you'll still need to clean more deeply from time to time by hand. Anyway, it does a great job. It SOMETIMES gets confused about thresholds and will spend a ton of time trying to get over them, and sometimes it gets over them no problem. It has a lot of strategies to get over thresholds and I've never had one get "stuck," though I've wanted to help him when he is struggling! It does require maintenance. I have had to manually clean out the on-board dirt receptacle when it has sucked up a bottle cap or something that blocked it from emptying at the dock. You have to put in water and empty the dirty water frequently. A NOTE ABOUT WATER: add a few tablespoons of isopropyl alcohol (rubbing alcohol) either 70% or 90% to the clean water, and maybe a drop or two of dish soap (no more). This will make the floor dry faster and also keep the dirty water tank from growing anything that smells horrible. I have yet to have a bad smell at all from the dirty water and I've left water in there for days and days before. If I could, I'd get the kit (do they make one for this robot?) to fill and empty water to the utilities. But alas, I'm too lazy for that, and am not really set up for it.

This thing is a game changer. My wife hasn't stopped talking about how clean the floors look since we set it up — and honestly, she's right. Out of the box, it was packaged like it was built to survive anything, and arrived quickly with zero damage. Setup was dead simple and it got to work immediately. The 11,000Pa suction is no joke — it picks up everything, and the auto mop washing and solution refill mean we barely have to think about it. The extendable side brush gets into corners we used to have to do manually. Performs well beyond what we expected at this price point. Highly recommend for anyone who wants genuinely clean floors without the effort.

It took a while to dial in the settings on the app and I'm still making small adjustments. It does go through water a lot faster then expected. I have to refill the fresh water about every other day. Thats really my only slight negative. Everything else about this is amazing. To those who have problems with it going in circles when it gets on carpet, I had the same problem. Once I set up a carpet zone in the app then it behaved. I think it got confused since originally I had set up my the app as having laminate throughout the house. I assumed that it would automatically know the difference but after I set up the carpet zones in the app and gave it instructions it worked perfect. Our laminate floors have never been cleaner. The mop function is probably the best thing about this and that's saying something. My wife was skeptical but she says this actually does as good a job as hand mopping. I'm not exaggerating. It doesn't even leave streaks. Our dogs have free run of the house and with a doggy door they're in and out all day tracking in dirt. I have the smart clean feature turned on and it mops every night, sometimes twice. The object avoidance so far has been nearly perfect. It did try to suck up a black charging cable but it was on dark colored carpet so I'm not surprised it didn't recognize it. Our carpet rug has high pile so the mop heads did slightly touch it but that's an easy fix by just having the robot vacuum first while leaving the mop heads at the base then mopping after. We have 2 other entry rugs with shag carpet that this really dosnt like. The side brush got twisted up in it last night and I thought it had destroyed it but I was able to untangle it without problems. I love this mop. I spent a week researching before purchasing. I watched several videos on YouTube and narrowed down the features that I wanted before making my decision. I found this when it was on sell for under $500. I don't believe you need to spend a lot of money (over $1000) to get a good vacuum any more. This is our 3rd robot vacuum and I'm excited to see how for the technologies come in just a few short years. If you wait until these high end flagship vacuums have been out for while, you can pick them up at a steal. This was cheaper then the shark mop vac we bought from Costco a few years ago and the upgrade in technology is mind blowing. We also have had fun with the find the pet function on this. When we were at a family party the other night, I turned on the front facing camera on the app, then set it to free roam around the house searching for our pet until it located them. My Mom and Sister were blown away. I did purchase separately, the 3 year warranty. I figure if it goes out after 3 years then the technology will be to the point where I'm ready to upgrade anyway. Very happy so far and I feel like I made the right choise. Update: this morning the vacuum was stuck on the shag rug placed by one of the exterior doors. It had a completely dead battery. I had to pick it up and manually put it back on the charger. A few hours later I looked in the app and my vacuum had sent me a message. It read, "the Dreame mop vacuum has gotten stuck on this carpet several times, may I recommend that we turn it into a no-go zone?" It had the settings button under neath the text so I clicked it and it had already mapped out a no-go zone around that rug that I just needed to agree to. Wow.

I waited a few weeks to leave a review for this vacuum mop combo. My tile is dark and smooth textured so everything shows up on it. I have four dogs and three kids so as you can imagine my floor needs mopping everyday haha! It's nice to have a little buddy to help me out on the days I am too tired to vacuum or mop myself. This machine not only does a great job vacuuming, but mopping as well! The mop was the part that I was really picky about because I already have a Roomba vacuum. I like that it cleans its own mop pads and dries them when it's finished. It does a decent job mopping, it took me a little bit in the app to get the no mop zones (carpeted rooms) marked correctly but once I did it worked great. The app is pretty easy to navigate. You can have the machine mop and vacuum in the same job, mop only, or vacuum only. I love having these options! It also has a camera on the front and does a great job avoiding obstacles and it lights up whenever it's in a dark room so it can see where it's going. I'm really impressed with all the features on this thing compared to other similar models that I tried before this one. I got another brand for Christmas and was not impressed, then bought another brand and wasn't impressed with that one either so this one made the cut out of three haha. When spending this much money on a machine you have to be picky! :)

UPDATE: After speaking with Dreame customer service, we came to the conclusion that a different model would work better for my use case. They exchanged my old vacuum for a new model, and I am now very satisfied with the replacement. I have updated my score from 2 stars to 4 to reflect the positive resolution. This does not change my thoughts on this model of vacuum, but does make me more confident in Dreame support going forward, as the new model works brilliantly. TL/DR: Excellent hardware, good software, with the major flaw of not always returning to the dock successfully, with sketchy tile cleaning performance. The performance of this robot vacuum/mop is quite good. The battery and pickup capacity is more than enough for each of my ~1200 sq. ft. floors, the WiFi functionality and the app are excellent, and the noise is right in line with what I would expect based on my experience with other brands. It struggles a bit with the tile in my bathroom, but overall does a good job on my home’s carpet, vinyl, and hard wood flooring. The (sold separately) tri-cut brush is a revelation. We have pets; and regularly cleaning the brush of their hair was always a nuisance has always been a struggle, but the special brush Dreame sells really does work to cut most of the pet hair that would otherwise tangle your main brush. If the minor struggle with my bathroom tile was the end of the story, I’d probably give a 5 star review. The problem: this robot struggles to return to its dock. The robot will finish a job, then try to return to the dock to charge, empty, and wash its mops. Unfortunately, it frequently gets stuck on the lip of its dock ramp, and is unable to dock without human intervention when the dock is placed on carpet. For our use case, moving the robot to a hardwood floor is just not feasible. And having to regularly move the robot back after it finishes vacuuming and before it will mop, makes it less automatic than I hoped for at this price point. I really wish I could heartily recommend this robot, but if you have a lot of tile flooring, or if having to frequently manually reset the robot on its base so it can finish the job is a deal breaker to you, it might be worth checking other options.

a neta le dudé un poco por el precio, pero ha resultado ser una gran inversión. Entre el relajo de Mateo y el montón de pelo que sueltan Petra y Thiago, mantener el piso limpio todos los días era una friega. Esta aspiradora tiene una potencia brutal. Algo que me latió mucho es el mecanismo que extiende el trapeador; limpia al ras de la pared y de los muebles, no deja nada sucio. Levanta tierra, moronas y todos los pelos de los perros sin broncas. La cámara y los sensores trabajan muy bien, esquiva los juguetes y no se anda atorando en todos lados. Además, la base es otro boleto: aspira la basura al depósito, lava los trapeadores con agua caliente y los seca para que no apesten. Básicamente te olvidas del aseo, solo le pones agua limpia de vez en cuando y ella hace el resto. La aplicación va directo al grano y es fácil de programar. Si quieren una aspiradora que realmente haga la chamba y les ahorre tiempo, esta es la buena. Totalmente recomendada.
