Nearly perfect

HARPREET S BRARDecember 4, 2025

Great robot vacuum and mop. The main reason I got this one is due to its hot water mop cleaning. I found that it really does a good job automatically cleaning the mop pads. It also has a setting where it run a second pass on extra dirty rooms depending on how dirty the mop pads are. For maintenance I mostly just have to change the water in the dock and clean the robots filter every few weeks. Other than that you need to sometimes clean the dock and replace the dust bag when it’s full. The robot does a really good job mopping. It does about as good at vacuuming as other robots, good on hardwood okay on carpet. The mop extends the edge of baseboards and the spinning brush extends into corners getting most of the floor. I find that the mop sometimes doesn’t make full contact with the floor so I have to use the deep cleaning mode The robot has some weird mapping, going in very unusual routes and sometimes stopping to think. Overall, it’s a great robot requiring very little maintenance for less than $500 Read more

Great performance and very convenient! This robot vacuum and mop picks up dust, hair, and debris really well, and the mopping feature leaves floors fresh and clean. It navigates smoothly, is easy to use, and runs quietly. I love the scheduling and hands-free operation—it saves so much time. Highly recommended for everyday cleaning! Read more

Excellent Value – Performs Like a Premium Robot Vacuum

NickJuly 27, 2025

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.

By far the best robot vacuum we've ever had.

David FSeptember 14, 2025

The media could not be loaded. 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. Read more
