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 so many other areas I had to move on. Since then, I have had mostly Roborock vacuums. I have owned the S6, S7 , 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 skipped 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 brus no longer spins on carpet by default. You have to do some trickery to get it to spin on carpet. Which is stupid to me, I looked around and they saw this is because its 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 is 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.

Robot floor cleaning technology has definitely improved a lot since I purchased my old Sharp vacuum only robot. But which one to choose in December 2024? I'm something of a gadget guy and when I purchase something like this, I like to do my research. I'd recommend a couple of youtube channels that will help, "Vacuum Wars" and "Just a Dad". At the time of writing, the Dreame L40 ultra was ranked third on Vacuum wars, behind two Roborock vacuums. After using this Dreame, I'd have to say I rank it at the top. The three robots i considered were the three rated best by Vacuum Wars. Namely the Roborock Qrevo Curv, the Roborock Qrevo Slim and this Dreame L40 Ultra. I rejected the Curv because it doesn't have the greatest obstacle avoidance. We have a lot of extension cords on our floor at home. Plus, the Curv was an extra $250 over the Dreame. So, I got the Dreame and set it up. Initial impressions were positive, but I soon hit a snag. During the first mapping I left a bedroom door closed. Didn’t appear to be a problem. The Dreame successfully cleaned the house rooms it had access to. However, later when I opened the final door, the Dreame went down the hallway to the bedroom and got confused. It forgot its existing map, forgot the base station location and started creating a new map from scratch. I wasn’t sure what was going on, so I emailed Dreame technical support. They were responsive but could not provide a solution. My initial thought was that perhaps there was a Wi-Fi problem at that end of the house, but the solution turned out to be to rerun the mapping from scratch. I concluded that the Dreame software is written such that once the floor map is finalized, only small modifications can me made to it from then on. Moral of this story: when you first run your Dreame L40, make sure it has access to all the rooms that you want it to clean. Since then, it has been running fine and cleans all rooms without getting lost. It’s nice to be able to select specific rooms for a cleaning cycle. Before I resolved the above problem, I ordered a Roborock Qrevo Slim so as to not to miss the black Friday price. Hence, I was able to compare the two and choose which to keep. Both vacuums clean very well but the Dreame definitely has the edge in obstacle avoidance. After the Slim climbed onto wires in our family room for the sixth time and tried to eat a power adapter, the choice became clear. Also, the Slim had some bugs in its Android app such that it would not let me rename a room. The room count is limited to 15 for the Roborock app. The Dreame does not have these problems. I also like the fact that the Dreame has a cleaning solution tank and can mix this into the water automatically. Plus, the Dreame just looks better. The Dreame L40 Ultra won. The Roborock Qrevo Slim was returned.

Have used it daily for a week now and it's been flawless. Never stuck, all features work perfectly, and it cleans quietly and quite well. Battery life is best we have had but it can recharge and return to work where it left off if needed. Cleaning is easy.

Buen articulo, pero lo compre y a la semana bajo 130 dolares mas

I love this vac/mop. More powerful suction than my last robotic vacuum and the mop feature works great. It keeps the floors clean, avoids wetting the carpet areas and is one of the quietest robotic vacs I have known. I am nothing but impressed with this unit and would highly recommend it to anyone looking to save time with every day chores

This Robot Vac/Mop is very good at cleaning the house. You will be shocked at how much dirt it picks up and how much the mop picks up as well. It really makes my house feel so much cleaner. It’s nothing like the first robot vacs that came out years ago. You can set this app up to clean your house however you would like and on your schedule. It’s actually pretty quick and efficient at getting the job done also. This robot has been enjoyed by the entire family!
