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

Amazing where we’ve come since my first Roomba
I was coming from an older iRobot Roomba i7, so this was an eye-opener.My old vacuum would bounce off of things and had a rudimentary mapping system. The Dreame L40 Ultra on the other hand has a built in camera and LIDAR sensors to both map and avoid obstacles making it a much more functional robot vacuum because you don’t have to babysit it as much to get it to actually do what you want. It feels sturdy and the base isn’t an eyesore. I don’t have a large house, so the battery in the vacuum unit is sufficient to vacuum and mop my whole house in one pass.In terms of the mopping features, I am impressed at what it is able to accomplish for its size. It’s never going to get every hard stain off of the floor, but for a day to day minor mopping, it does a great job at keeping the floors clean. The vacuuming power is kind of middle of the road. If you have hile pile carpet, you might want to look at one of the higher suctioning units, but for my needs, this robot vacuum is fine.I’m not going to go into a list of all the features, but the remote control/remote video feature is convenient if you want to check on your house while you are not home. This particular vacuum also has magnetic mops which drop in the base so you can vacuum separately without worrying about whether or not your carpet is going to get wet. The app is surprisingly functional (coming from the iRobot one). It makes partitioning your house easy enough and allows you to set no go zones, etc. The obstacle avoidance, while not being top class as the $1000 units, is still very good. I only had one case where the mop got tangled in a cord and it required my attention in about 20-25 hours of use so far.Overall, at a sub $500 price point in late 2025, this is a great “budget” robot vacuum. I would say it does about 90% of what a $1000 one does, but at half the price! If you don’t have a ton of high pile carpet, this is a great vacuum for your house.
